Function Health overview
Function Health is a yearly membership that gives you a wide, repeated lab panel with clinician review, not a one-off kit. For around $499 per year you get 100+ biomarkers with testing twice a year, all organized into a dashboard that tracks change over time. Pricing can shift, so see current pricing at Function Health before you buy.
The pitch is comprehensiveness. Instead of guessing which single panel to buy, Function tests across heart, hormones, thyroid, metabolism, nutrients, heavy metals, inflammation, liver, kidney, and autoimmunity in one sweep. A clinician reviews the results and you get a plain-language action plan, so the numbers come with context rather than a raw PDF.
Pros
- One of the widest standard panels available, with 100+ markers in a single draw.
- Two draws per year built into the price, which is what makes trending useful.
- Clinician review and an action plan on every result.
- A dashboard that keeps your history in one place.
Cons
- Highest upfront cost of the at-home category, and it is an annual commitment.
- Requires a venous lab draw, so it is not a fully at-home finger-prick experience.
- Pricing and availability can differ in some states such as New York and New Jersey.
- Overkill if you only want to check one thing, like thyroid.
Pricing: Around $499 per year for the full membership, with optional advanced add-ons available for an extra fee. See current pricing at Function Health, as plans can change.

Everlywell overview
Everlywell sells individual at-home test kits, so you buy exactly the one panel that answers your question and skip the rest. Prices run from roughly $49 to $249 per kit, samples are collected at home, and they are processed by CLIA-certified labs with physician oversight.
The model is targeted and flexible. If you suspect a thyroid issue, you buy the thyroid kit (TSH, Free T3, Free T4, and TPO antibodies) for around $149. If you want to investigate food reactions, the food sensitivity panel screens IgG reactivity to dozens of foods. There is no membership required, and many kits are HSA and FSA eligible, though an Everlywell+ membership exists for people who test more often.
Pros
- Low entry price and no subscription required for one-off kits.
- True at-home collection by finger-prick, saliva, or urine depending on the panel.
- Wide menu of specific panels, so you pay only for what you need.
- Many kits are HSA and FSA eligible.
Cons
- Each kit covers a narrow set of markers, so a full-body picture means buying several kits.
- Costs add up fast if you stack multiple panels, eroding the price advantage.
- Some panels, such as IgG food sensitivity testing, are debated within the medical community.
- No single longitudinal dashboard the way a membership service offers.
Pricing: Roughly $49 to $249 per kit depending on the panel, with HSA and FSA accepted on many tests.
The verdict: which one should you choose?
There is no single winner here because the two services are built for different jobs. Match the tool to your goal rather than chasing the lower sticker price.
Choose Function Health if you want a recurring, whole-body baseline you can trend across the year, you value clinician review and an action plan on every marker, and you are comfortable with a venous draw and an annual fee. It is the better fit for a serious yearly checkup mindset where the goal is catching small changes early across many systems.
Choose Everlywell if you have one specific question right now, like thyroid, hormones, or metabolism, and you want a low-cost at-home kit with no subscription. It is the smarter buy when you do not need 100+ markers and would rather pay $49 to $249 for the exact panel that matters to you.
If your priority is longevity-style monitoring at a friendlier price than the premium memberships, it is worth comparing both against Superpower (around $199/year for 100+ biomarkers with a physician-reviewed dashboard). And if fast, finger-prick at-home blood testing is your main concern, SiPhox Health offers HSA and FSA eligible kits with quick turnaround.

Frequently asked questions
Is Function Health or Everlywell cheaper?
Everlywell is cheaper to start, with single kits from about $49 to $249, while Function Health is around $499 per year. But Function includes two draws a year and 100+ markers, so per biomarker it can be the better value if you would otherwise buy several Everlywell kits.
Do either of these require a doctor visit?
No. Everlywell tests are ordered by an independent physician and collected at home, and Function Health uses a partner lab draw with clinician review built in. Neither requires you to book your own doctor appointment first.
Are the results from Everlywell and Function Health accurate?
Both use accredited labs. Everlywell processes samples at CLIA-certified labs, and Function Health runs venous samples through partner labs with clinician review. As with any test, accuracy also depends on following the collection instructions correctly.
Can I use HSA or FSA funds?
Many Everlywell kits are HSA and FSA eligible, and SiPhox Health kits are as well. Function Health membership eligibility can vary, so confirm with your benefits administrator before purchasing.
What if I only want to check one thing, like thyroid?
Then Everlywell is the better fit. You can buy just the thyroid kit (TSH, Free T3, Free T4, and TPO) for around $149 without committing to a yearly membership. Save Function Health for when you want the full-body annual picture.
