Short answer — for most people I recommend LetsGetChecked or Everlywell for an at‑home testosterone test; for clinician‑grade detail pick ZRT Laboratory, and for women wanting a fertility‑focused panel pick Modern Fertility. Reasons and quick buying tips below.
Top picks
- LetsGetChecked — Best overall for accuracy + medical support. Uses a finger‑prick blood sample analyzed in CLIA‑certified labs, offers clear total‑testosterone results (and often panels including SHBG/estradiol), and provides nurse/doctor follow‑up if results are abnormal. Good turnaround time.
- Everlywell — Best consumer‑friendly/value option. Easy ordering, finger‑prick (dried blood spot) testing through CLIA labs, clear dashboard and interpretation. Reliable for total testosterone screening at a competitive price.
- ZRT Laboratory — Best clinician‑grade / most detailed. Offers dried‑blood‑spot and saliva options and more comprehensive hormone panels (total and free testosterone, SHBG). Widely used by clinicians for nuanced hormone workups.
- Modern Fertility — Best for women/fertility‑focused testing. Includes testosterone as part of a broader reproductive hormone panel, female‑oriented interpretation and actionable guidance.
What to look for when buying
- Sample type: blood (finger‑prick/dried blood spot) is preferred over saliva for accuracy of testosterone measurement.
- Lab quality: choose tests analyzed by a CLIA‑certified lab.
- Measures: tests that include SHBG (or report free testosterone) give better clinical context than total testosterone alone.
- Timing: testosterone is highest in the morning — collect samples early (typically 7–10 AM) and follow the kit instructions.
- Support: pick a service that offers medical/nurse follow‑up if results are abnormal.
Cost & turnaround
- Expect $50–200 depending on panel size. Turnaround is typically 2–7 business days from sample receipt.
Next steps
- If you have symptoms (low libido, fatigue, erectile dysfunction, irregular cycles, etc.) or an abnormal at‑home result, follow up with your primary care doctor or an endocrinologist — they may order a confirmatory venous blood test and additional workup.
If you tell me whether you’re male or female and whether you want just testosterone or a broader hormone panel, I can recommend the single specific kit and link to it.
