Short answer: there’s no one “best” for every woman — it depends on which hormones you need and whether you want a fertility focus, adrenal/stress information, or a simple screening with medical follow-up. That said, these are the top at‑home options people choose and why:
-
DUTCH Complete (Precision Analytical)
- Why: Most comprehensive sex‑hormone + adrenal panel for at‑home testing. Measures estradiol/progesterone/testosterone and their metabolites plus a multi‑sample diurnal cortisol profile and cortisol metabolites (useful for adrenal/stress assessment, estrogen metabolism, PCOS/perimenopause workups).
- Sample: dried urine (multiple collections across a day).
- Good if: you want in‑depth hormone metabolism and adrenal info.
-
Modern Fertility
- Why: Smartphone‑friendly, clear reports and easy clinician access; best for fertility/ovarian reserve testing (AMH) and cycle planning. Good educational dashboard and provider follow‑up options.
- Sample: finger‑stick blood (AMH and other reproductive markers).
- Good if: your main concern is fertility or ovarian reserve.
-
LetsGetChecked
- Why: Broad menu of clinically actionable blood‑based hormone tests (FSH, LH, estradiol, progesterone, testosterone, thyroid panels), with nurse/physician follow‑up and direct‑to‑consumer shipping. Uses CLIA‑certified labs.
- Sample: finger‑stick blood or standard blood draw depending on test.
- Good if: you want a convenient blood‑based panel with medical support.
-
Everlywell
- Why: Affordable, easy kits for basic hormone and thyroid screening and clear online results. Good for a first pass screening.
- Sample: finger‑stick blood or saliva (depending on test).
- Good if: you want a lower‑cost, convenient screening test.
-
ZRT Laboratory
- Why: Clinician‑grade saliva and dried blood spot testing used by many providers; good if you’re working with a practitioner and want flexible sample types (saliva for free cortisol/sex hormones).
- Sample: saliva or dried blood spot.
- Good if: you need practitioner‑level saliva testing or specific timing protocols.
Quick practical tips
- Match the test to your goal: AMH/ovarian reserve vs cycle hormones vs adrenal/cortisol vs thyroid.
- Timing matters: e.g., FSH/estradiol often on cycle day 2–4; progesterone mid‑luteal (~day 21 of a 28‑day cycle) to confirm ovulation; AMH anytime; DUTCH cortisol requires multiple timepoints across a day.
- Verify the lab is CLIA‑certified and read whether the kit measures metabolites (DUTCH) vs parent hormones only.
- Consider tests that include clinician/nurse follow‑up if you want help interpreting results.
- Always review abnormal results with your healthcare provider before changing meds or treatments.
