Function Health vs Hundred Health

What is Function Health, and what is Hundred Health?

Function Health and Hundred Health both sell an annual blood-testing membership with a clinician-built plan, and they differ in what sits beside the blood work.

Function Health leads with the testing itself: 160+ lab tests across two draws, read by clinicians who write an analysis and action plan. Supplements come as guidance since SuppCo joined Function, and prescriptions are not offered.

Hundred Health sells a strategy. Its homepage promises "100+ lab tests detecting early risk across 1,000+ conditions," combined with medical records and wearable data into a 100-day plan.

Function adds a second draw. Hundred adds a prescription program and discounted supplements.

What does Function Health include?

For $365, Function Health members get 160+ lab tests across two draws, plus a clinician-reviewed action plan and a results dashboard.

Function lays out the experience in four steps:

1. Schedule tests — Share your health history, then book the first draw.
2. Get insights — Clinicians read the results next to that history to pick out what matters and what to do about it.
3. Take action — Retest every 3 to 6 months to watch what changes.
4. Monitor for life — Your data builds into a record that shows patterns and early signs.

Draw one measures about 115 biomarkers, and the mid-year draw repeats about 60 of them at no added charge. Function's SuppCo arm ties supplement guidance to your results, though it does not run a member-priced storefront.

What does Hundred Health include?

A Hundred Core membership runs $199 a year. It bundles 100+ lab tests, a clinician-built protocol, wearable and medical record connections, and AI-powered insights.

Hundred describes a three-step path:

1. We build your complete health record — Labs at 5,000+ partner sites or from home, while Hundred gathers your past records and connects your wearables.
2. Your health results, finally explained — Labs and wearable data are read together, compared against peers, and paired with physician-led insights.
3. Get your 100-day action plan — A clinician-built protocol spans nutrition, supplements, exercise, and lifestyle.

Hundred's FAQ says members do not interact with a physician directly inside the app. After a critical result, someone on Hundred's clinical team contacts you directly, and everything else goes through in-app chat or email.

What biomarkers do Function Health and Hundred Health measure in 2026?

Counted the same way, the two annual draws land close together. Function's draw measures 116 to 118 biomarkers, and Hundred's published list adds up to 113 to 116 once add-ons are set aside and repeats counted once.

The 160+ versus 100+ headline gap mostly reflects Function's second draw. Both counts include urinalysis and calculated values.

Function's add-on catalog includes:

• Heart, thyroid, and autoimmunity — Genetic heart risk, extended thyroid, celiac, and autoimmunity panels.
• Hormones, toxins, and nutrients — Extended hormone health, heavy metals, PFAS, and extended vitamins.
• Cancer, brain, and allergies — The GRAIL cancer test, Alzheimer's detection, and ApoE risk.
• Scans — Heart CT, lung CT, and MRI through Ezra.

Hundred's add-on markers include:

• Heart and kidney — Lipoprotein (a), LDL particle number, fibrinogen, cystatin C, and uric acid.
• Thyroid and hormones — Thyroid antibodies, free T3, IGF-1, and prolactin.
• Toxins and nutrients — Arsenic, lead, mercury, omega fatty acids, homocysteine, and zinc.
• Planned imaging and screening — Hundred's FAQ says members will be able to sign up in 2026 for Galleri, Prenuvo, and DEXA.

What are the official 2026 membership prices for Function Health and Hundred Health?

Function Health costs $365 a year, while Hundred Health is $199 a year, shown as $16 a month with annual billing. Hundred is the lower of the two prices.

New York and New Jersey members pay Hundred an added lab fee of up to $248 a year, passed to the lab. Function charges its state fee when you arrive for the draw, and the amount is not published.

At-home draws through Function are offered in select places only, and fees differ by location. Optional add-on tests at Hundred may carry separate fees, and Function's add-ons are priced separately too. Both memberships are HSA/FSA eligible, and so is Hundred's prescription program.

Prescriptions and supplements inside the membership

Hundred Health offers prescription access, and Function Health does not.

Hundred sells clinician-guided prescription therapies as a separate care program, which prescribes weight-loss medication from $99 a month, on top of the membership. No prescription is written without a consultation first, and some states require that visit by live video. New Jersey, Alaska, Illinois, and Mississippi fall outside the program.

Supplements split the same way. Hundred members get up to 20% off retail on a curated store, and non-members pay full price. Function offers guidance instead, matching a supplement routine to your biomarker data without selling it at a member rate.

One annual panel versus two draws a year

Function Health includes two scheduled draws a year, and Hundred Health includes one annual panel.

Function's second draw rechecks about 60 markers from the first, and its steps suggest retesting every 3 to 6 months. Hundred's membership lists its tests as included annually, while its FAQ recommends "a full retest every 100-days."

How do Function Health and Hundred Health turn results into a plan?

Both memberships start results quickly and finish the plan more slowly.

Function's first batch typically arrives within 48 hours of testing. Reviewers put the wait for the clinician-reviewed plan at three to four weeks, since Function states no timeline.

Hundred shows some results within 24 hours, with the full panel taking about two weeks. Your protocol is generated once every result is in and onboarding is complete. Both include a biological age.

Where are Function Health and Hundred Health tests available?

Function Health runs draws at 2,000+ locations across 48 states, with Hawaii, Rhode Island, and Puerto Rico left out.

Hundred Health draws at 5,000+ partner labs, or sends a phlebotomist to your home. In-lab visits are unavailable in Hawaii, North Dakota, South Dakota, West Virginia, and four U.S. territories (the U.S. Virgin Islands, American Samoa, the Northern Mariana Islands, and Guam). In-home draws are unavailable in 16 states, including Washington, Vermont, and Wyoming.

Who is Function Health best for, and who is Hundred Health best for?

Function Health is best for:

• People who want a second draw built into the same annual fee.
• People who want biological age re-measured with each draw.
• People who want supplement advice read against their own results.

Hundred Health is best for:

• People who want one annual panel for $199 a year.
• People who want prescriptions available through the same company.
• People who want a discount on supplements they already buy.

The bottom line

Function Health and Hundred Health both turn a yearly blood panel into a clinician-built plan. Function gives you two draws and a set schedule for $365. Hundred gives you one panel for $199, plus a prescription program and supplement pricing.

Both models stop at the same point: what to do with the plan. Function offers supplement guidance and no prescriptions, while Hundred sells prescriptions apart from the $199 and lists its imaging and screening add-ons as planned for 2026.

Superpower costs the same $199 a year as Hundred, below Function's $365, for 100+ biomarkers from one draw. Its marketplace books DEXA, VO2 max, and whole-body MRI now, next to supplements at up to 20% off, and prescriptions are available when clinically appropriate, priced separately. Results come back within 10 days, where Hundred's full panel typically takes about two weeks. Superpower AI writes your Superpower Protocol from them and updates it whenever fresh data lands, with AI and care team support on hand. Superpower reports that 93% of members found their action plan more useful, even life-changing, than a yearly checkup.
