Short answer — there’s no single “best” for everyone. Pick by what you want measured and how you want it delivered. My top recommendations:
-
DUTCH Test (Precision Analytical) — Best for the most comprehensive hormone picture
- Why: Dried-urine metabolite testing gives detailed sex-hormone metabolites plus 24‑hour cortisol/metabolite mapping and cycle-mapping options. Clinicians commonly use it for complex cases (PCOS, perimenopause, adrenal issues, estrogen metabolism).
- When to choose: You want a deep dive into estrogen metabolites, progesterone, and adrenal/cortisol rhythms.
-
LetsGetChecked — Best for simple, clinically validated blood hormone panels and telehealth follow-up
- Why: Finger‑prick blood kits processed in CLIA labs, with nurse/doctor support and treatment options in many states/countries. Good balance of accuracy, convenience, and medical follow-up.
- When to choose: You want standard blood-based measurements (FSH, estradiol, testosterone, thyroid markers, etc.) plus access to clinicians and prescriptions if needed.
-
Modern Fertility (or similar fertility-focused kits) — Best for family‑planning / ovarian reserve testing
- Why: Focused panels (AMH, FSH, sometimes estradiol and thyroid) and clear interpretation for fertility and timing decisions.
- When to choose: Your primary goal is assessing ovarian reserve and fertility planning.
-
Everlywell — Best for convenience and lower-cost screening
- Why: Easy ordering, at‑home sample collection, straightforward results dashboard. Good for initial screening if you want basic hormone checks.
- When to choose: You want an affordable, easy first look or symptom-check.
Quick guidance on choosing and using any at‑home hormone test
- Decide what you want to know: fertility (AMH/FSH), menstrual-cycle function (estradiol, progesterone), adrenal/cortisol, or thyroid. Not all kits measure everything.
- Sample type matters: blood (finger‑prick) is the clinical standard for many hormones; dried urine (DUTCH) is best for hormone metabolites and diurnal cortisol; saliva has limitations for some hormones.
- Timing matters: progesterone should be measured mid‑luteal (about 7 days before expected period), FSH early follicular (day 2–4) for cycle-day specific tests; AMH can usually be measured any day.
- If results will change treatment or you have serious symptoms (infertility, irregular bleeding, suspected thyroid disease), follow up with your primary care provider, reproductive endocrinologist, or an endocrinologist. Many services above offer clinician consults.
If you tell me your main concern (fertility, irregular periods, perimenopause, fatigue/stress/adrenal symptoms, thyroid concerns), I can recommend the single best kit for your situation and explain exact timing for sample collection.
