Everlywell vs Function Health: at-home kits vs a $365 lab membership
Last updated September 3, 2026.
Everlywell and Function Health both sell health testing direct to consumers, but the sample in your hand tells the story. Everlywell ships you an at-home kit: a finger prick or similar collection you mail back. Function Health sends you to a real clinical lab for a blood draw, 160+ tests on a $365-per-year membership.
What does each one cost?
Everlywell prices per kit: per its own site, its Food Sensitivity Test measuring IgG reactivity to 96 foods is $199, and its at-home Women's Health Test covering 11 biomarkers is $249. Function Health charges $365 per year, billed annually, covering 160+ lab tests at home or at 2,000+ partner labs. Per test, Function is cheaper by volume. Per convenience, Everlywell never asks you to leave the house.
What is the experience like?
Everlywell is the simplest possible testing experience: order a kit, collect the sample at your kitchen table, mail it to a certified lab, read results online. It suits targeted curiosity: one hormone panel, one food panel. Function Health is a committed annual program: a very large venous blood draw, a dashboard, and doctor-reviewed insights tracked year over year. Everlywell sells a kit. Function sells a system.
Which one should you pick?
If you want to answer one specific question without leaving home, Everlywell's kits are the low-friction option. If you want the broadest clinical-grade screen and are willing to sit for a real blood draw, Function. A caution that applies to both: a positive screening result is the start of a conversation with a clinician, not an answer. Pymander, the free text-first AI doctor behind this site, can help you make sense of results for free, and its safety escalation logic is documented in its safety architecture working paper.

Common questions
How much does Everlywell cost?
Per kit: its Food Sensitivity Test is $199 and its Women's Health Test covering 11 biomarkers is $249, per its own site. No membership required.
How much does Function Health cost?
$365 per year, billed annually, per its own site, covering 160+ lab tests with blood draws at home or 2,000+ partner labs.
What is the difference in how samples are collected?
Everlywell kits are self-collected at home, typically a finger prick, and mailed to a lab. Function Health uses full venous blood draws at clinical labs or via at-home phlebotomy.
Are at-home test results reliable?
The labs processing them are typically certified, but screening panels are not diagnoses. Any flagged result should be confirmed and interpreted with a clinician before you change your diet, medication, or life.
Which is better for ongoing tracking?
Function Health, by design: same large panel on an annual schedule with a dashboard. Everlywell is better for a single targeted question.
Do these replace a doctor?
No. Both sell testing. Diagnosis and treatment need a clinician, and a free Pymander AI doctor consult can help you interpret results first.
