Function Health review: tests, cost, and my experience (2026)

What lab tests are included in Function Health?

Function includes 100+ biomarkers at the initial draw and 60+ tests at a mid-year follow-up. Its advertised 160+ annual lab tests include repeats, rather than 160 different biomarkers. The panel includes ApoB, Lp(a), advanced LDL particles, thyroid hormones and antibodies, sex hormones, vitamin D, iron studies, omega fatty acids, lead, mercury, and routine blood and urine testing.

This table groups the distinct entries in our database, including calculated results. Some markers depend on sex, eligibility, or reflex testing. The included-test list was rechecked against Function’s website on October 16, 2026. For more detail, see the full Function Health biomarker list.

How does Function Health testing work?

Join through Function’s website, complete the health-history questions, and schedule your initial lab visit. Function works with a nationwide laboratory network, including Quest Diagnostics, and offers at-home draws in selected locations for an additional charge. Most people can complete initial testing in one appointment; some circumstances require a second visit. Follow the preparation instructions in your order.

Results appear in your account as the lab finishes processing them. A clinician reviews the results and your health history, then provides written notes and guidance. Specialty tests can take longer than routine bloodwork, so the first results and the complete report may arrive at different times.

The membership also includes a smaller follow-up panel midway through the year. Check which markers will be repeated and when the visit must be used; a mid-year retest does not repeat every test from the initial panel. Function’s standard membership provides testing and written interpretation, without ongoing treatment or prescriptions.

What was my experience with Function Health’s results?

The blood draw was straightforward. Function made it easy to order advanced tests such as ApoB, Lp(a), lipid particles, and hormones together. The dashboard was the strongest part of my experience: I could browse by body system, open an individual result, and see its range and history.

In the app examples below, the first screen summarizes results, the second organizes them by category, and the third shows ApoB over several draws. Function offers web, iPhone, and Android apps. I tend to use the web dashboard when reviewing more of my data at once.

On October 12, Function and Google Health announced a partnership to let U.S. users import Function lab results into the Google Health app later this fall.

My clinician-written summary mostly restated flagged results and offered broad lifestyle and supplement suggestions. It gave me context, but I wanted more discussion of my history and what to do next. That is the main limitation I would consider before renewing.

The example note below shows how Function presents a written summary of results. Function also offers Private AI Chat and Protocols; the promotional screenshots show those features labeled beta. They provide another way to explore results and plans, while the standard membership still does not establish an ongoing relationship with a treating physician.

Is Function Health worth $365 a year?

Function Health’s $365 membership includes roughly $1,114 in lab tests, but competitors like Empirical now offer panels from $190.

Function’s price makes the most sense if you want its broader initial panel and will use the included follow-up testing. Advanced LDL particles, thyroid antibodies, omega fatty acids, and heavy metals distinguish it from less expensive panels focused on routine and cardiovascular testing.

If you already know which few tests you want, compare the cost of ordering those directly. If you want to discuss results, treatment, or medication, compare doctor access as well as testing. A longer marker list does not establish that every test will be useful for you.

The standard membership is $365 annually and renews at the then-current rate. At-home draws, optional tests, and imaging cost extra; New York and New Jersey laboratory fees may apply. Function does not bill insurance, although eligible HSA/FSA funds can be used.

See the Function Health cost guide for fees and renewal, the discount-code history for offers, or the detailed value analysis for lab-price comparisons and methodology.

How does Function Health compare with competitors?

Function Health's primary competitors are Superpower, Empirical Health, and Whoop Advanced Labs.

Superpower lists a $349 annual membership and advertises a limited-time $150 discount. Empirical offers a lower-cost single panel, doctor access, and a separate repeat-testing program. This table compares the named packages; it does not treat a one-time purchase as a year of testing.

Function’s additional coverage compared with Superpower is concentrated in advanced lipids, omega fatty acids, and heavy metals. The table below groups the overlap and differences in our panel database. For care and pricing differences, read Function Health vs Empirical Health or Function Health vs Superpower.

Coverage reflects the named packages in our database; individual report fields and calculated values are counted separately. Confirm the current list and any add-ons before ordering.

Other testing models include WHOOP Advanced Labs for its wearable experience, Vitals Vault for pay-once panels, and Goodlabs for eligible blood donors. The Function alternatives guide compares these options in more detail.

What do other Function Health users say?

The user reports I reviewed often praised panel breadth and the results dashboard. Recurring criticisms included generic written notes, support problems, and frustration importing older results. Function has since added historical-result imports, so older complaints may describe an earlier version. See the Function Health reviews guide for the source threads and the difference between app ratings and reports about testing or follow-up.
