The blood tests required before TRT start with two early-morning total testosterone tests on different days plus compatible symptoms or signs. If testosterone is low, the AUA recommends LH. Before treatment, measure hemoglobin and hematocrit, plus PSA if you're over 40. Prolactin, free testosterone, estradiol and fertility testing are conditional.

That core list is shorter than many clinic panels. And one of the tests on almost every online "TRT panel" is conditional rather than universal — while at least one major online clinic's published starter kit does not list LH or hematocrit. We'll show you both.

The short version

Minimum: usually two blood draws, because the second morning test and the safety tests can go on the same order. Cost: at the direct-order labs we checked in mid-September 2026, one total testosterone test cost $65 to $75 cash. See the full price breakdown.

What changes the answer:

• Under 40? The AUA doesn't require PSA before treatment. The Endocrine Society uses age and risk instead.
• Want kids now or later? Fertility testing comes before any testosterone. Jump to that section.
• Already on testosterone? Your tests and timing are different. Jump to monitoring.
• Very low result, new bad headaches or vision changes? That points to an endocrinologist, not a TRT subscription.

TRT Provider Guide is the independent decision resource for testosterone replacement therapy — helping U.S. adults understand how low testosterone is evaluated, compare online and local care models and providers, and choose the next step that fits their health needs, fertility plans, budget, state, and care preferences, with every material claim verified and dated.

This page is for U.S. adult men who are about to be tested, or were just handed a lab order or a clinic's starter test. It's not for women, teens, gender-affirming care, or performance use. Those follow different rules.

What blood tests are required before TRT? The full checklist

Answer: Before TRT, U.S. guidelines require two early-morning total testosterone tests and a clinician's review of symptoms. Once testosterone is confirmed low, the AUA adds LH to look for the cause, hemoglobin and hematocrit as a safety baseline, and PSA for men over 40. Other tests are added only when something specific triggers them.

Every test on a lab order has a job. Some prove the problem is real. Some find out why. Some check whether it's safe to start. The rest answer questions only some men have.

Here's every common pre-TRT test, sorted by the job it does and who actually requires it.

The Pre-TRT Blood Test Decision Matrix

Sources: AUA Testosterone Deficiency Guideline, statements 1–12 and 23; Endocrine Society guideline and July 16, 2026 statement; FDA-approved testosterone cypionate label. Checked September 30, 2026.

A few words you'll see on every lab report:

• Total testosterone — all the testosterone in your blood, both the part stuck to proteins and the small free part.
• Free testosterone — just the unbound part.
• SHBG (sex hormone-binding globulin) — a protein that grabs testosterone. Too much or too little can make total T look misleading.
• LH (luteinizing hormone) — the signal your brain sends telling your testes to make testosterone.
• FSH (follicle-stimulating hormone) — the brain's signal for sperm production.
• Hematocrit — the share of your blood made of red blood cells. Testosterone can push it up.
• PSA (prostate-specific antigen) — a protein made by the prostate. A starting number lets your clinician spot changes later.
• Hypogonadism — the medical name for low testosterone caused by a problem in the testes or the brain signals that control them.

"Commonly ordered" is not the same as "required for every man." A clinician may have a good reason to order a metabolic panel, lipids, A1c or thyroid tests for you. That doesn't make them part of the universal list. If a clinic calls a 50-marker panel "required," ask which markers answer a guideline requirement and which are their house protocol.

Why estradiol isn't on the required list

Estradiol shows up on nearly every commercial TRT panel. Many men assume it's mandatory.

It isn't. The AUA recommends checking estradiol before treatment in men who have breast symptoms or gynecomastia (enlarged breast tissue). It rates that recommendation Expert Opinion — its lowest-evidence category. For everyone else, it's optional. The guideline sets no universal estradiol target for men on TRT.

That doesn't make the test useless. It just means a clinic can't honestly call it "required" for you unless you have a reason.

Required by whom? The three rulebooks that decide your labs

Answer: The clearest U.S. standards come from the American Urological Association guideline, the Endocrine Society guideline, and product-specific FDA prescribing information. The AUA and Endocrine Society both require repeat early-morning testosterone confirmation for a new diagnosis, and the FDA-approved testosterone cypionate label also instructs prescribers to confirm low morning testosterone on at least two separate days. They differ on fasting, free testosterone and prostate monitoring.

When a page says a test is "required," ask: required by whom?

Here's what each rulebook says, in plain English.

Sources: testosterone cypionate prescribing information; AUA guideline statements 1–12; Endocrine Society guideline resources and July 16, 2026 statement. Checked September 30, 2026.

The drug label says it too

Most people think the two-test rule is just doctor advice. It is also printed in the FDA-approved prescribing information for testosterone cypionate.

The FDA-approved label for testosterone cypionate tells prescribers to confirm low testosterone, before starting, with morning blood levels measured on at least two separate days. That reinforces the same repeat-testing principle found in the AUA and Endocrine Society guidance.

Where the rulebooks disagree

• Fasting. The Endocrine Society recommends morning fasting testing. The AUA does not make fasting a universal requirement. Follow the ordering clinician and laboratory instructions, especially when other tests are drawn at the same time.
• Free testosterone. The Endocrine Society's 2018 guideline recommends free testosterone when total T is near the lower limit or when SHBG-altering conditions are present; its 2026 statement also stresses accurate total and free testosterone measurement. The AUA uses total testosterone as the main diagnostic test and gives free T a supporting role in selected cases.
• PSA. The AUA says check it in men over 40. The Endocrine Society ties it to age and risk. If you're 40–54, ask which approach your clinician follows and why.

What changed in 2026 — and what didn't

On June 18, 2026, HHS announced that FDA was requesting updates to testosterone product labels. The requested changes included removing the age-related-hypogonadism limitation of use and revising prostate-cancer and benign-prostatic-hyperplasia language. FDA's own testosterone information page still describes these as requested updates, so this page does not treat every product label as already revised.

What it didn't touch: the two-morning-test requirement.

A month later, on July 16, 2026, the Endocrine Society restated its standard: at least two early-morning fasting tests. It also urged labs to use testosterone tests certified by the CDC's hormone standardization program (called HoST). Its reason is striking. Without standardized tests, the Society warns, the same blood sample can read "low" at one lab and "normal" at another.

Bottom line from all three rulebooks: a quiz, one home-kit reading, or a "you pre-qualify" screen is not a diagnosis.

The right TRT provider is not the same for every person — it depends on whether low testosterone has been properly evaluated, your symptoms and health history, your fertility plans, your state, your insurance or cash-pay preference, your treatment-format preference, your budget, and whether online or in-person care is the better starting point. Some situations belong with primary care, urology, endocrinology, reproductive urology, or urgent or emergency care when the symptoms warrant it. Because a general answer cannot resolve those for you, use TRT Provider Guide's Find My TRT Path tool to map your situation to the right care route and the questions to ask before you pay.

Why do you need two morning testosterone tests before TRT?

Answer: Testosterone rises and falls through the day and from one day to the next. A late blood draw or an acute illness can pull one reading down. Two early-morning tests on different days help show whether low is persistent, which is why both major guidelines require repeat morning testing for diagnosis and the testosterone cypionate label also calls for confirmation on at least two separate days.

Your testosterone isn't a fixed number like your height. It moves.

The AUA guideline puts real numbers on that:

• Time of day matters. In men aged 30 to 40, testosterone measured at 4 p.m. ran 20–25% lower than at 8 a.m. In 70-year-olds the drop was about 10%. Levels peak around 3 to 8 a.m. for men on a normal sleep schedule.
• One test swings a lot. The same man's results can vary widely from one draw to the next. Taking two or three measurements cuts that variability by 30–43%.
• Being sick lowers it. In one small study of young men with respiratory infections, total testosterone fell about 10% on average, and up to 30% in some groups.

So one low result is a reason to get a second test, not a diagnosis. If the first test is low and the second is normal, the AUA leaves it to your clinician whether a third test makes sense.

"My first test came back 236. Can I just start?"

No. We see this question a lot, and we understand the frustration.

But under every rulebook above, one number isn't a diagnosis — not 299, not 250, not 236. The next step is repeat testing and a clinician who looks at the results together with your symptoms or signs and medical history. Testosterone is a Schedule III controlled substance in the United States and requires a valid prescription. Do not start, stop or change testosterone outside clinician care.

Does one result under 300 ng/dL mean I need TRT?

No. The AUA calls 300 ng/dL a reasonable cut-off that supports a diagnosis — when you also have symptoms and two morning tests agree. A 301 doesn't mean your symptoms are imaginary. A 299 doesn't mean you need a prescription. For what a result can and can't prove, see TRT eligibility requirements.

How far apart should the two tests be?

The AUA says there's no proven best gap. What matters: a different day, early morning, and ideally the same lab using the same method, so you're comparing like with like.

---

How do you prepare for a testosterone blood test?

Answer: Book the draw in the early morning and follow the ordering clinician's fasting instructions; the Endocrine Society recommends morning fasting testing. Avoid testing during an acute illness when possible, and do not stop medicines or start supplements to manipulate the result. Using the same lab and method for repeat tests can make the comparison cleaner.

Small mistakes here cause wasted draws. Here's the checklist:

1. Go early. Guidelines call for early-morning testing because testosterone varies through the day. If you work nights or have an unusual sleep schedule, tell the ordering clinician rather than guessing at the timing.
2. Fast if told to. The Endocrine Society recommends fasting morning testing. Other tests on the same order may also have preparation requirements, so follow the lab order rather than a generic internet rule.
3. Don't test while sick. A cold, flu or major illness can pull your number down. Ask whether to reschedule.
4. Keep your medicines as they are. Don't stop anything on your own. Do tell the clinician about opioids, steroids like prednisone, prior testosterone or anabolic steroid use, and supplements — especially biotin, which can interfere with some lab tests.
5. Skip the "testosterone boosters." Starting a supplement right before testing just muddies the result.
6. Use the same lab both times. Different labs and methods can give different numbers for the same blood.
7. Ask one smart question: "Is this testosterone test CDC HoST-certified?" The CDC publishes the list of certified tests. It's the standardization the Endocrine Society is asking for.

Home finger-prick or a lab draw? A home kit describes how the sample is collected, not whether a specific assay is adequate for a diagnostic decision. Acceptance varies by clinician and testing method. Here's how home and lab testosterone tests compare.

---

What order do the blood tests happen in?

Answer: A new diagnostic workup starts with repeat morning testosterone testing. If testosterone is low, LH and any indicated cause-finding tests follow; before treatment, hemoglobin/hematocrit and, under AUA guidance, PSA for men over 40 are checked. Some clinicians combine these tests into the second draw, but the exact sequence depends on the patient and clinic.

Here's the order we'd expect a careful clinician to follow, drawn from the guidelines above:

1. Draw 1 — morning total testosterone. Early, fasting if instructed, not while sick.
2. Draw 2 — a second morning total testosterone, on a different day. Depending on the first result and your history, the clinician may add LH, a CBC (for hemoglobin and hematocrit), and PSA if you're over 40. Fertility concerns may trigger a separate reproductive evaluation rather than a one-size-fits-all FSH order.
3. Triggered tests, only if needed. Prolactin if LH is low or low-normal. Free testosterone and SHBG if total T is borderline. Estradiol if you have breast changes. A specialist referral if testosterone is very low.
4. Decision visit. A licensed clinician reviews both results, your symptoms, your safety baseline and your fertility plans. Only now does a prescription come up.

Copy this and send it to your doctor or clinic

Hi — before we discuss testosterone treatment, I'd like my evaluation to include:

1. Two early-morning total testosterone tests on different days (same lab if possible)
2. LH
3. A CBC with hemoglobin and hematocrit
4. PSA (I'm over 40) — delete if under 40
5. If fertility matters to me, tell me whether I need a reproductive evaluation, FSH or semen analysis

Could you also tell me which assay the lab uses, and whether any other tests you order are required for me or part of your standard panel? Please don't start a prescription until these results are back. Thank you.

Which extra tests depend on your situation?

Answer: Extra tests are added for a reason. Prolactin is checked when LH is low or low-normal. Free testosterone and SHBG help when total testosterone is borderline. Estradiol is for breast symptoms, FSH and semen analysis are for fertility, and very low testosterone may call for a specialist. If a clinic can't name the reason for a test, ask.

One warning on free testosterone. Method matters. The Endocrine Society says to measure free T by a method called equilibrium dialysis, or to calculate it from total testosterone, SHBG and albumin. It advises against relying on "direct analog" free-T tests, which it calls inaccurate. If your report says "free testosterone," ask how it was measured.

---

Do you also need a CBC, CMP, lipids, A1c or thyroid test?

Answer: Sometimes, but not because TRT universally requires them. A CBC is the usual way to get the required hemoglobin and hematocrit. A metabolic panel, lipids, A1c and thyroid tests look at broader health or other causes of your symptoms. Your clinician may order them for good reasons specific to you.

That's not a knock on big panels. Tiredness, low drive and weight gain have lots of possible causes, and checking a few of them is sensible. Just know the difference between "required to diagnose low testosterone" and "a good idea for your overall health."

Not a blood test, but don't skip it: blood pressure. In 2025, the FDA required class-wide testosterone label updates that include blood-pressure information from ambulatory blood-pressure studies. Expect your clinician to take a baseline reading before you start.

What changes if you want children?

Answer: Testosterone therapy can suppress sperm production, and a testosterone blood test says nothing about sperm count. If current or future fertility matters, tell the clinician before treatment. The AUA calls for a reproductive health evaluation in men interested in fertility, while AUA/ASRM guidance says testosterone monotherapy should not be prescribed to a man interested in current or future fertility.

This is the section to read twice if kids are even a maybe.

Testosterone taken from outside the body tells your brain to turn down its own signals — including FSH, the one that drives spermatogenesis (the body's sperm production). Your testosterone number can look great while your sperm count drops. How much, and whether or how fast it recovers, varies from man to man. Nobody can honestly promise you'll stay fertile, lose fertility, or recover on a set schedule.

What the AUA says:

• Before treatment: men interested in fertility should have a reproductive health evaluation (Moderate Recommendation, Grade B).
• Counseling: clinicians should discuss testosterone's long-term effect on sperm production with men who want future fertility (Strong, Grade A).
• Fertility-specific guidance: AUA/ASRM says testosterone monotherapy should not be prescribed to a man interested in current or future fertility. The AUA testosterone-deficiency guideline also says exogenous testosterone should not be prescribed to men who are currently trying to conceive.

Medicines such as clomiphene and hCG work differently from testosterone. They are not TRT and are not interchangeable with it. Clomiphene use in men is off-label; hCG has distinct FDA-approved indications and should not be presented as ordinary TRT. None of these options guarantees fertility. If conception is a current goal, a reproductive urologist or other male-fertility specialist is the better starting point.

What do the results mean for your next step?

Answer: Results decide the care route, not just the prescription. A low-then-normal pair usually means another test. Low testosterone with low LH needs a look for a cause. A high baseline hematocrit, a raised PSA or persistently high prolactin should be worked up before any testosterone. We can't read your results, but here's what the guidelines say clinicians typically do.

The Endocrine Society also advises against starting testosterone in some situations until they're evaluated or resolved. These include untreated severe sleep apnea, a heart attack or stroke in the past six months, uncontrolled heart failure, a blood-clotting disorder, and certain prostate findings.

Chest pain, severe shortness of breath, fainting, or sudden leg swelling? That's not a lab question. Call 911.

---

Why does one TRT clinic order five tests and another order fifteen?

Answer: Clinic panels mix different jobs — confirming the diagnosis, finding the cause, checking safety, and broad wellness screening. More markers don't automatically mean better care, and fewer aren't automatically unsafe. What matters is whether the tests answer the required questions before a prescription is written.

Here's the thing marketing pages won't tell you: a bigger panel can still miss a required test.

A 50-marker "longevity" panel can skip the second morning testosterone draw. A five-marker home kit can include PSA but not hematocrit. Neither the count nor the price tells you whether the diagnosis and safety questions got answered.

So don't judge a clinic by its biomarker count. Judge it against the short list at the top of this page.

---

How can you tell whether a clinic's bloodwork is enough?

Answer: Ask whether the clinic confirms a new low-testosterone diagnosis with repeat morning testing, checks LH when testosterone is low, obtains hemoglobin/hematocrit before treatment, addresses PSA when appropriate, and has a plan for fertility and abnormal results. Clear answers are a better signal than the number of biomarkers in a marketing panel.

Before you pay, ask these ten questions. Save the answers.

1. Do you require two early-morning testosterone tests on different days before a new prescription?
2. If my testosterone is low, do you check LH to look for the cause?
3. Is hemoglobin and hematocrit checked before my first prescription?
4. When do you check PSA, and how does my age change that?
5. What happens if I might want children?
6. Which tests on your panel are required for me, and which are your standard extras?
7. What happens if a result needs specialist follow-up before treatment?
8. Who reviews my results — and what's their license type?
9. Will you wait for my lab results before prescribing?
10. What will the labs cost beyond the advertised price — including the second test?

Question 9 sounds obvious. It isn't. You'll see why in the next section.

What do online TRT clinics publish about testing before prescribing?

Answer: Published testing pathways differ. As of our September 30, 2026 check, Hone's current Premium schedule shows a $65 initial panel with CBC/hematocrit, LH and PSA, then a $25 confirmatory panel with total testosterone and prolactin if TRT is being considered; a separate Hone retesting article still describes PSA and hematocrit on the confirmatory test too. Male Excel's $99 starter kit names five markers and does not list LH or hematocrit. Taurus Meds advertises an eight-biomarker test but does not name the full panel on the offer page we checked.

Affiliate disclosure: TRT Provider Guide may earn compensation from some providers mentioned elsewhere on the site. This page does not use a provider CTA because the testing evidence here does not support turning this informational question into a provider recommendation.

The Pre-Prescription Lab Audit

We compared what each provider publishes against the required list above. These are provider-stated public pages, not a patient's actual lab order.

Checked September 30, 2026 on each provider's own current pages. These are provider-published workflows, not an audit of individual patient orders. "Not named" does not mean "not done."

Hone Health: the clearest published repeat-testing pathway we found

Of these three providers, Hone publishes the clearest repeat-testing sequence before TRT, but its help center is not fully consistent about the confirmatory panel. The current Premium schedule places CBC/hematocrit, LH and PSA in the initial panel and lists total testosterone plus prolactin on the $25 confirmatory panel. A separate current retesting article says confirmatory testing includes total testosterone, PSA, prolactin and hematocrit.

Here's what Hone's current help center says:

• The $65 initial at-lab panel includes CBC/hematocrit, LH, PSA, total testosterone, calculated free testosterone, SHBG and other markers.
• If TRT is being considered, Hone's current Premium schedule requires a $25 at-lab confirmatory panel with total testosterone and prolactin.
• A separate Hone retesting article lists total testosterone, PSA, prolactin and hematocrit on confirmatory testing. Because those pages conflict on panel composition, we do not claim one four-marker confirmatory panel applies to every current Hone patient.
• Both sources agree that repeat testosterone testing is used before TRT.
• Current Premium follow-up labs are included in the $155 monthly membership.

CBC/hematocrit, LH and PSA are already part of Hone's current $65 Premium initial panel. Its current Premium schedule describes the separate $25 confirmatory panel as total testosterone plus prolactin, while a separate retesting article lists PSA and hematocrit there too.

What to know before you pay: the first Premium lab panel is $65. If TRT is being considered, Hone lists the confirmatory panel at $25 at-lab. Premium is $155 a month plus medication, and Hone says follow-up labs and visits are included. Hone also describes the Premium membership as an annual clinical program billed monthly, with cancellation allowed at any time.

Editorial take: Hone's public pathway is easier to compare with guideline-based repeat testing than the other two pages we checked. That is not a finding that Hone is the right provider for every reader, and this page does not convert that transparency advantage into a provider recommendation.

Male Excel: a simple starter kit with important unanswered testing questions

Male Excel's pitch is simplicity. It's $99 for a home blood-spot kit plus an online consult. After that, membership is $99 a month plus medication. That includes provider check-ins every 60 days and full panels every six months.

Here's the honest tradeoff. Male Excel does not build a second morning test or a hematocrit check into its first step. Its kit measures five markers: total testosterone, estradiol, DHEA-S, free T3 and PSA. And its homepage says its providers can prescribe before your lab results arrive when clinically appropriate. If a guideline-matching sequence is your priority, Hone is the better fit.

Male Excel's public materials do describe ongoing 60-day reviews and repeat lab monitoring. But the published starter pathway leaves a material question for a new diagnosis: how and when a second morning testosterone result, LH and baseline hematocrit are obtained before testosterone is prescribed. Ask the clinician directly before relying on the starter kit as a complete diagnostic workup.

Also know:

• Male Excel says its providers don't prescribe in Alabama, Alaska, Arkansas, Connecticut, Hawaii, Idaho, Louisiana, Minnesota, Mississippi, New Hampshire, or Rhode Island.
• Male Excel says some prescribed medications may be compounded by licensed U.S. compounding pharmacies. Compounded drugs are not FDA-approved.
• It doesn't take insurance. It says FSA, HSA or HRA funds may be reimbursable.

Before using any clinic's starter panel: compare it with the checklist in What order do the blood tests happen in?, then ask how the clinic handles repeat morning testing, LH and baseline hematocrit before treatment.

Taurus Meds: a low advertised entry price with an undisclosed full marker list

Taurus advertises $49 for a lab test with eight biomarkers at Labcorp or Quest, plus a 15-minute video consult. The catch is disclosure. Its offer page does not name the full eight-marker panel or describe a second morning draw. Its quiz uses "pre-qualify" language, but Taurus also says prescriptions remain at the clinician's discretion. Its FAQ says medication payment occurs after labs and before the clinician call, with a refund if the clinician finds the patient ineligible.

None of that proves the panel is bad. It means you should get the list in writing before you pay.

Your own doctor: an insurance-based route that may reduce lab cost

If you have insurance, primary care can often order the needed evaluation and refer when the cause or risk profile calls for urology or endocrinology. Your cost depends on the plan, deductible, network and medical-necessity rules. Can your primary care doctor prescribe TRT?

---

Can you start TRT without blood work — or use an online or at-home test?

Answer: A new diagnosis of testosterone deficiency should not be made from a symptom quiz alone. U.S. guidelines require compatible symptoms or signs plus consistently low, properly measured testosterone, and testosterone requires a valid prescription. Federal rules currently allow qualifying DEA-registered clinicians to prescribe Schedule II–V controlled substances by telemedicine without a prior in-person exam through December 31, 2026, when all federal and state conditions are met.

A quiz isn't a test. The AUA says questionnaires should not be used to decide who gets testosterone.

Home kits. A finger-prick or blood-spot kit may be used by some services, but whether it is acceptable for a diagnostic decision depends on the assay, collection method, clinician and applicable protocol. Do not assume that “at home” or “at lab” alone proves test quality. Compare home and lab testing.

The 2026 telemedicine rules. Under the current federal temporary extension, a DEA-registered practitioner may prescribe Schedule II–V controlled substances by telemedicine without a prior in-person evaluation through December 31, 2026, if all listed conditions are met. State law and ordinary prescription requirements still apply. Because the temporary rule expires at the end of 2026 unless replaced or extended, recheck the federal rule before relying on it in 2027.

The practical move: keep full copies of your lab reports — PDFs with units, reference ranges and collection times. They can travel with you to any clinician if your care has to change. Is online TRT legal?

---

What blood tests are needed after you start TRT?

Answer: Once treatment starts, the key tests repeat. The AUA says to check testosterone after an initial interval and then every 6 to 12 months. The Endocrine Society says to check hematocrit at 3 to 6 months and then yearly, plus PSA when prostate monitoring applies. When to draw depends on your treatment format.

Two lines worth knowing:

• Hematocrit above 54%: the Endocrine Society guideline says therapy should be stopped until hematocrit decreases to a safe level, with evaluation for hypoxia and sleep apnea, then therapy may be restarted at a reduced dose under clinician care.
• Normal level, no improvement: the AUA says to discuss stopping treatment at 3–6 months if testosterone is normal but symptoms haven't improved.

Timing is tied to the format. An injection is drawn at a different point than a gel. Always record the time of your last dose and the time of the draw. See which providers include ongoing monitoring and what to watch for on TRT.

---

What if your results come back normal or borderline?

Answer: A normal result is useful information, not a failure. Tiredness and low drive have many causes, including sleep apnea, weight, thyroid problems, stress and medicines. If testosterone is borderline, free testosterone and SHBG may clarify it, and the AUA leaves room for clinical judgment in men with strong symptoms.

The AUA admits some men test above 300 and still have real symptoms. It asks clinicians to use judgment and extra tests — not to wave them off, and not to rubber-stamp them. The Endocrine Society says clinicians should rule out reversible causes first, like obesity or medicines such as opioids and steroids.

What we'd avoid: shopping for a clinic that says yes. If you've done the tests the right way and they're normal, the better next step is finding out what is causing how you feel.

How we researched this page

Answer: We read the guidelines and drug label ourselves and checked each provider's own pages on September 30, 2026. We didn't buy a test, enroll, or talk with any provider's clinicians. Provider statements are labeled as provider-stated. Our conclusions come from those verified facts.

What we actually verified

Verification date: September 30, 2026

Primary medical and regulatory sources we read:

• AUA Testosterone Deficiency Guideline (statements 1–31) and its Table 7 on lab testing
• Endocrine Society guideline resources and its July 16, 2026 statement
• The FDA-approved prescribing information for testosterone cypionate
• The Federal Register notice extending telemedicine prescribing flexibilities through December 31, 2026
• The AUA's announcement of the June 2026 HHS/FDA labeling request

Verified from provider pages (provider-stated):

• Hone: $65 initial Premium lab panel; CBC/hematocrit, LH and PSA on that initial panel; repeat testing required when TRT is being considered; current Premium schedule lists a $25 at-lab confirmatory panel with total testosterone and prolactin; separate retesting article also lists PSA and hematocrit on confirmatory testing; $155 Premium monthly fee plus medication
• Male Excel: $99 kit and consult; five named markers; can prescribe before results arrive; $99 membership; 60-day check-ins; states not served; compounded testosterone
• Taurus: $49 eight-marker test; markers not named; Labcorp/Quest; "You pre-qualify" quiz; medication payment before the clinician call

What we could not confirm:

• Which current Hone confirmatory-panel composition applies across every plan and collection pathway, because Hone's public help articles conflict
• The eight markers in Taurus's test
• Whether each provider accepts outside lab results
• What any individual patient is actually ordered or prescribed

What we did not do: buy tests, complete intake, or speak with clinicians. This is a public-document check, not a hands-on review.

Our method is documented in How We Review TRT Providers. It separates verified facts, provider-stated facts, customer-experience signals and editorial conclusions. See also our Editorial Standards and Corrections. Found something out of date? Tell us.

Frequently asked questions about blood tests before TRT

What blood tests are required before TRT?

Two early-morning total testosterone tests on different days, plus symptoms that fit. Once testosterone is confirmed low, the AUA adds LH, hemoglobin and hematocrit, and PSA for men over 40. Other tests depend on your results and plans.

Do you need two blood tests for TRT?

Yes. The FDA-approved testosterone label, the AUA and the Endocrine Society all call for testosterone measured on at least two separate mornings before treatment. One low result is a reason to retest, not a diagnosis.

Can I start TRT with one blood test?

Not under U.S. guidelines or the FDA label. A single reading can be thrown off by timing, illness or lab method. A careful clinician confirms it with a second morning test first.

What time of day should testosterone be tested?

Early morning, usually around 7 to 10 a.m., when levels peak for most men. In men in their 30s, afternoon results can run 20–25% lower. Night-shift workers should time the draw to their wake-up and tell the clinician.

Do I need to fast before a testosterone blood test?

The Endocrine Society recommends a fasting morning test. The AUA doesn't insist on it. Follow your order's instructions — other tests on the same order may need fasting.

What testosterone level do you need for TRT?

There's no single qualifying number. The AUA calls under 300 ng/dL a reasonable cutoff, but only with symptoms and two morning tests. The Endocrine Society calls a level near 300 ng/dL a common threshold. See TRT eligibility requirements.

Is hematocrit checked before TRT? What's too high?

Yes. The AUA says hemoglobin and hematocrit should be measured before offering testosterone. Its lab table says the pre-treatment hematocrit should be under 50%. On treatment, the Endocrine Society says to stop therapy above 54% until it comes down.

Do I need a PSA test before TRT if I'm under 40?

The AUA recommends PSA before treatment for men over 40. The Endocrine Society uses a shared decision for men 55–69, and for men 40–69 at higher risk. Under 40, ask your clinician whether your risk changes that.

Why is LH tested before TRT?

LH shows whether the problem is in your testes or in the brain signals that control them. The AUA strongly recommends it for anyone with low testosterone, because the cause can change the treatment and the specialist.

Do I need estradiol tested before TRT?

Not for everyone. The AUA recommends estradiol before treatment only for men with breast symptoms or enlarged breast tissue. Many clinics include it anyway. That's their protocol, not a universal requirement.

Is free testosterone required before TRT?

Not always. It's most useful when total testosterone is borderline or SHBG may be off. The Endocrine Society says to use equilibrium dialysis or a calculation, not a direct analog test.

Do I need a CBC or CMP before TRT?

A CBC is the usual way to get the required hemoglobin and hematocrit. A CMP isn't universally required to diagnose low testosterone, but many clinicians order it to check liver, kidney and blood sugar.

Is an at-home finger-prick test enough for TRT?

It can be a starting point. Many clinicians want a lab draw to confirm, and all the guidelines still require two morning measurements. Compare home and lab tests.

How much do blood tests before TRT cost?

In mid-September 2026, one total testosterone test cost $65 to $75 cash at the direct-order labs we checked. Two tests plus the safety labs cost more. Insurance often covers tests a clinician orders for symptoms. See current prices.

Can I use lab results from my own doctor?

Often, but every clinic sets its own rules. Common ones are how recent the results must be, which tests they need, and whether morning timing is documented. Send the full report, not a screenshot of one number.

What tests do I need before TRT if I want kids?

Tell the clinician about current or future fertility before treatment. The AUA calls for a reproductive health evaluation in men interested in fertility, and AUA/ASRM guidance says testosterone monotherapy should not be prescribed to a man interested in current or future fertility. A semen analysis and hormone testing may be part of a fertility evaluation when indicated. Read TRT and fertility.

What blood tests are needed while on TRT?

Testosterone every 6–12 months after the first check (AUA). Hematocrit at 3–6 months and then yearly (Endocrine Society). PSA when prostate monitoring applies. Plus repeat tests after any dose change.

The bottom line

The core list is short. A new diagnosis starts with two early-morning testosterone tests plus compatible symptoms or signs. If testosterone is low, LH helps with the cause. Before treatment, hemoglobin and hematocrit matter, and the AUA recommends PSA for men over 40. The rest should have a reason.

The order matters as much as the list. For a new diagnosis, repeat morning testing should confirm that low testosterone is persistent before treatment is considered. Ask what each test is for, what happens if a result is abnormal, and how fertility plans change the care route.
