“What’s best” depends on which hormones you need and why (fertility, menopause, adrenal/cortisol, thyroid, cycle troubleshooting). Below are top at‑home options by common use case, with why I’d recommend each.
- DUTCH Complete (Precision Analytical)
- Best for: comprehensive sex‑hormone metabolism + adrenal cortisol rhythm.
- Why: dried‑urine panel measures estrogens, progesterone metabolites, and multiple cortisol samples to show daily pattern — more complete metabolite info than a single blood spot or saliva test.
- Modern Fertility
- Best for: fertility planning and ovarian reserve.
- Why: convenient finger‑prick blood test for AMH, FSH, estradiol and related markers. Designed for people trying to understand fertility/ovarian reserve with clear, clinician‑reviewed results.
- ZRT Laboratory
- Best for: clinician‑grade saliva and blood‑spot testing (free hormones and cortisol).
- Why: offers saliva panels for free cortisol/testosterone and blood‑spot for other hormones. Widely used by practitioners for cycle/timing‑sensitive assessments.
- Everlywell or LetsGetChecked
- Best for: easy consumer at‑home snapshots with telehealth/physician support.
- Why: user‑friendly kits (finger prick) with clear reports and optional provider follow‑up. Good if you want convenience plus basic clinical guidance.
- If you need highest clinical accuracy (particularly thyroid or detailed biochemical levels)
- Consider: venous blood draw ordered by your clinician or via services like Quest Diagnostics/Labcorp or HealthLabs (not fully “at home,” but most accurate).
- Why: venous blood is the clinical gold standard for many hormones (TSH, free T4/T3, comprehensive lab panels).
Important notes
- Timing matters: progesterone needs a mid‑luteal sample (about 7 days before expected period), cortisol requires multiple timepoints, AMH can be taken any day.
- No at‑home kit replaces clinical evaluation. Use tests together with a clinician for interpretation and next steps.
- Check what each kit measures (some omit thyroid, AMH, or metabolites) and whether results are clinician‑reviewed.
If you tell me which hormones or goal you care about (fertility, menopause, fatigue/stress, irregular cycles), I can recommend the single best kit for your situation and what timing to use.
