Function Health and Hone Health both turn blood testing into a health plan, but they are built differently. Function Health sells a yearly membership with twice-yearly testing included. Hone Health runs a clinical membership with labs on a schedule, video visits with physicians and prescription treatment when a physician decides it fits. FitScript publishes this page and is shown alongside them as a third option built around reading the labs you already have. Every fact below is linked to where it came from.
FitScript publishes this comparison and is one of the services compared. Competitor facts come from each company's own website as of October 15, 2026. Prices and features change, so check their current terms before you decide.

Function lists one membership at $365 per year, charged annually, which it also expresses as $1 a day. Its pricing page states that the membership renews at the then-current price, and its FAQ notes that testing in New York and New Jersey can cost more because of state regulations. The membership covers 160+ lab tests a year, clinician review of every result, a personalised protocol and member pricing on MRI and CT scans. Function is insurance-free and provides an itemised receipt for HSA or FSA reimbursement.
On flexibility, Function states that members can cancel and rejoin at any time.
Hone Health lists two memberships. Its how-it-works page shows Premium at $155 a month plus the cost of medication, with an initial test of $65, and Basic at $25 a month, with an initial test of $25 plus an onboarding fee. Its home page describes getting started at $65 for advanced lab testing of 50+ biomarkers, a telehealth consult with a licensed physician and a personalised plan, while the same how-it-works page notes that Basic members book a 30-minute physician consultation for a nominal fee, so what the first payment includes depends on the plan you choose.
Its help center describes both as annual clinical programmes billed monthly: Men's Premium totals $1,860 a year and Basic $300 a year, excluding medication, each charged as one twelfth of the annual fee per month. Medication is priced separately, with its testosterone page listing testosterone from $28 a month on top of the membership.

Function splits its 160+ yearly tests into two visits. The Annual Test covers 100+ biomarkers, and the Mid-Year Test covers 60+ biomarkers to track change, which Function says must be used before the annual renewal. Its published menu runs across heart, thyroid, hormones, metabolic health, liver, kidneys, nutrients, environmental toxins and autoimmunity, and includes markers such as ApoB, lipoprotein(a), LDL particle number, omega-3 levels and heavy metals such as mercury.
Function also lists practical details. Members fast for 8 hours and avoid seafood for 48 hours before heavy metal tests. Some members need two visits, for example people with an active menstrual cycle, so hormones are drawn at the right time, and members in Arizona because of state processing rules. Function is open to adults 18 and over who are not currently pregnant.
Hone Health states that it tests 50+ biomarkers across core health systems including cardiovascular, metabolic, hormones and thyroid. Its help center lists the Men's Premium panel as a thyroid panel, a sex hormone panel including PSA, a complete blood count, a lipid panel including ApoB, and a comprehensive metabolic panel. Premium members retest every three months and Basic members every six, and members can add DEXA scans, MRIs and extra lab panels.
Testing on a fixed rhythm is the point of Hone Health's model, since the physician reviews each new set of results alongside the last. That cadence suits people who are adjusting a treatment and want regular checks built in.

Hone Health offers a choice of 2,000+ Quest Diagnostics locations, and its home page states that testing can be completed at home or at a lab. Its help center explains that at-home kits are available only for men, with women completing testing at a lab location, and that an in-home or on-site draw is available through a GetLabs mobile phlebotomist, free for initial labs on some programmes, with members paying for GetLabs on follow-up labs.
Function states that the first batch of results typically starts arriving within 48 hours of testing. Each result comes with explanations written by doctors, action items and a clinician's full summary, and Function says a healthcare provider will call right away if a result is critical. Members can download results as a PDF to share with their own doctor.
Hone Health's help center states that lab panels typically return results about 10 business days after the blood draw, with physician review within one to two business days after results arrive, and that at-home panels usually take about four business days after the lab receives the sample. Results appear on a dashboard in a secure patient portal, where they can be downloaded and shared. Its help center notes that the Hone app is its mobile-friendly website rather than an App Store or Google Play download.
Function states that clinicians review every result and flag issues. For AI, members can stay in Function's Private AI Chat or securely connect their results and clinician notes to vetted partners including ChatGPT, Claude and Perplexity. Questions about membership or results go through member chat, and Function describes its service as deeper insight to use alongside your existing care.
Hone Health's consult is a private one-to-one video appointment with board-certified physicians who specialise in hormone health, metabolism and longevity. Premium members meet their clinician with each three-month retest and have unlimited messaging with their care team. Its testosterone page lists testosterone therapy as injections, cream or dissolvable troches, and its home page lists prescription hair-loss treatments. Its terms state that clinical services are provided by Broad Health, an independent physician-owned medical group, through the Hone platform.
Function lets members connect supported apps under Connected Apps to sync their health data, and invites members to upload results from their own doctor so everything is tracked in one place over time.
Hone Health accepts outside labs for the initial evaluation when they were completed within the last 90 days and all its required biomarkers are present, and its help center notes that the initial lab test is still purchased through Hone Health.
Function offers a large amount of testing for one published yearly price, with two scheduled draws so members can see change over a year. Its site lists 2,000+ Quest labs in 48 states, an at-home draw option, first results typically within 48 hours and clinician review of every result. Members who want imaging can add an annual MRI.
For people who want a broad, recurring panel managed for them and like having clinicians review the results, that structure is easy to follow.
Hone Health builds follow-up into the product. Premium pairs every retest with a clinician visit every three months and keeps a care team a message away, which is exactly the structure people managing a treatment tend to want. Its Premium panel covers the core hormone, thyroid, lipid and metabolic markers that ongoing care depends on.
It is also clear about cost. Its help center breaks each membership into a yearly total and a monthly charge, lists medication separately, and lets members pause rather than cancel when life gets in the way.
Function is a good fit for someone who wants a broad panel twice a year, with clinician review of every result, the option of an at-home draw and member access to MRI and CT. Its scheduled mid-year retest suits people who want to see change within a year without planning it themselves.
Hone Health is a good fit for someone who already expects to work with a physician on hormones, metabolism or weight, wants labs and a clinician visit on a fixed three-month rhythm, and is comfortable paying a monthly membership with medication on top.
FitScript publishes this page and is shown in the table as a third option. It is built around reading the labs you already have rather than around one fixed testing bundle. Protocol is $20 per month including a 7-day trial and covers Atlas, its AI, the Health Score and personalised recommendations on uploaded labs. Lab panels are sold one body system at a time, from $49 for a single test to $499 for FitScript Complete, and Peak adds provider access and two group coaching calls a week.
Its upload page accepts PDF reports from Quest, Labcorp, other testing services and hospital systems, as well as phone photos of paper printouts, and states that Atlas has a read in under a minute. So results from either service compared here can be uploaded and read against optimal ranges.

Start with the tests you actually want. A large biomarker count is useful when it covers the systems you care about, such as thyroid, hormones, heart, liver and kidney health. Read each provider's published list and look for the specific markers you have been told to watch, for example ApoB, fasting insulin or free T3, rather than comparing totals alone.
Next, think about how often you will retest. Seeing a number move after three or six months is often more useful than a single snapshot, so include the cost of a second draw in any yearly total. Check where you can be drawn, how long results take and whether a clinician reviews anything outside the standard range.
Finally, look at what happens after the results arrive. Some people want a clear written plan, some want to ask questions about their own numbers, and some want a licensed provider involved. Membership terms, renewal pricing and HSA or FSA eligibility are worth reading closely too, since they change over time.
Choose based on what you need most. Function Health sells a yearly membership with twice-yearly testing included. Hone Health runs a clinical membership with labs on a schedule, video visits with physicians and prescription treatment when a physician decides it fits. Read each company's current terms, since prices and features change.
Whatever you choose, a licensed clinician is the right person to interpret results that fall outside the standard range and to decide on any treatment.

Atlas is FitScript's AI. It reads every marker against optimal ranges as well as the standard range, builds a daily protocol and answers follow-up questions about your own results. The FitScore is one score built from your results, tracked over time.
Many people retest a panel after about three months to see whether changes in sleep, training or diet have moved the numbers, then every six to twelve months once results are steady. A clinician can suggest a schedule based on your own results.
No. FitScript publishes it and is one of the services compared. Every competitor fact links to that company's own site and shows the date we read it, so you can check anything that may have changed.
