Short answer: it depends on whether you want a convenient screening, the most clinically accurate serum test, or a deep metabolic picture. For most men who want an at‑home option that balances completeness, lab quality, and clinical follow‑up, I recommend Let's Get Checked. If you want a low‑cost screening, Everlywell is a good simpler option. For an in‑depth steroid/metabolite view use the DUTCH test. If you need gold‑standard accuracy, get a venous serum panel at Quest or LabCorp (ordered through your doctor or DirectLabs).
Recommendations and why:
-
Let's Get Checked
- Why: offers a comprehensive male hormone panel (total testosterone plus free testosterone/SHBG and often estradiol, LH/FSH, prolactin, DHEA‑S, PSA options), uses CLIA‑certified labs, provides physician review/telehealth follow‑up and medication referral if needed. Finger‑prick at‑home collection is convenient and results are easy to access.
- Best for: men who want a thorough at‑home screen plus clinical support.
-
Everlywell
- Why: reliable, user‑friendly at‑home dried blood spot tests at a lower price point. Their male hormone test covers total and calculated free testosterone, SHBG and estradiol in many panels and returns results quickly.
- Best for: cost‑conscious screening or initial check of testosterone-related symptoms.
-
DUTCH Test (Precision Analytical)
- Why: dried‑urine hormone test that measures steroid metabolites (testosterone metabolites, estrogen metabolites, cortisol rhythm). Excellent when you need a detailed view of hormone metabolism rather than just serum levels.
- Best for: complex cases (unexplained symptoms, poor response to therapy) or when you want metabolite and adrenal information.
-
Quest Diagnostics / LabCorp (via physician order, DirectLabs, or QuestDirect/Labcorp Patient Service Centers)
- Why: venous serum tests measured in hospital/touchstone labs are the clinical gold standard for total testosterone and many other hormones (albumin, SHBG, LH/FSH, prolactin, estradiol). More accurate than fingerstick for borderline cases.
- Best for: diagnostic confirmation, pre‑TRT baseline, or when precise lab values are required.
Also consider telehealth clinics that bundle testing + treatment (if that’s your goal):
- Roman, Hims, Defy Medical, Tone — they order labs through established labs and offer telemedicine for interpretation and TRT if indicated.
What to make sure your panel includes
- Total testosterone (always)
- Free testosterone or SHBG + albumin (to calculate free T)
- SHBG (important for interpreting total T)
- LH and FSH (to differentiate primary vs secondary hypogonadism)
- Estradiol (E2) — converts from testosterone
- Prolactin and DHEA‑S (helps evaluate pituitary/adrenal causes)
- PSA (if older than ~40 and considering TRT)
- Basic safety/monitoring labs if starting TRT: CBC, CMP (liver/kidney), lipids, HbA1c
Practical tips
- Test in the morning (ideally before 10 AM) when testosterone peaks.
- Repeat abnormal low levels with a second morning test to confirm.
- Understand limitations: finger‑prick/dried‑blood tests are convenient but slightly less precise than venous serum draws.
- Check that the lab is CLIA‑certified and that physician review is available if you want follow‑up.
If you tell me what you care about most (lowest cost, most hormones, telehealth/medication integration, or absolute lab accuracy), I can recommend one specific kit and a link to buy it.
