Quick answer: Based on function health reviews 2026 data, member sentiment remains largely positive for breadth of testing but has shifted since the price climbed to around $499 per year. The core membership still covers more than 100 biomarkers across two draws, the results interface is clean, and physician review is included. Where Function draws criticism is the add-on cost structure, occasional phlebotomy scheduling friction, and a price point that is now harder to justify when flat-rate competitors run comparable panels for about $199 per year.
What Function Health Reviews Actually Say in 2026
Across verified consumer platforms in early 2026, Function Health holds a 4.2 to 4.6 out of 5 range on most aggregate review sites, with the majority of positive feedback centered on the comprehensiveness of the panel and the ease of the digital dashboard. The complaints cluster around three themes: the price increase that took the membership from its original launch price to roughly $499, add-on tests that can push the annual spend to $700 or more, and the fact that some members expected more hands-on physician interaction than the platform delivers.
Still deciding if $500 for bloodwork is worth it? Compare Function’s panel against a 150-marker membership before you commit. One at-home Superpower draw checks 100+ biomarkers, physician-reviewed.
One detail that surfaces repeatedly in longer reviews: members who came from a traditional primary care annual lab experience are almost always impressed. Members who came from a concierge medicine background or who already ran their own labs through Quest or Labcorp sometimes find the panel less differentiated than they expected. That contrast tells you a lot about who Function is actually built for. For a deeper look at the history of member feedback, see our function health bad reviews roundup, which covers the recurring complaints in detail.
What Changed: The 2025 to 2026 Price and Panel Updates
Function Health raised its standard membership price to approximately $499 per year at some point in 2025, up from earlier pricing that hovered closer to $399. The company has not publicized the exact change date, but reviews from late 2025 onward consistently cite the higher figure. What members received in exchange was a modestly expanded panel in some categories and a redesigned results interface with better year-over-year trending tools.
The panel refresh added or upgraded biomarkers in hormonal health and cardiovascular risk sections. Apolipoprotein B (ApoB) and Lp(a) were already present in earlier versions, so the cardiovascular coverage was already strong. The 2026 iteration improved the contextualization layer, meaning the software now does a better job of explaining what a borderline result means in practice rather than simply flagging it red or yellow.
Add-on pricing did not decrease. Members who want full thyroid panels beyond TSH, heavy metals, or advanced gut markers still pay per test on top of the base membership. Some of those add-ons run $49 to $149 each. The full picture of what those add-ons cost is covered in our function health cost breakdown, but the short version is that a fully loaded Function membership can realistically reach $700 to $800 annually once members start adding the tests their specific situation calls for.
Is Function Health Worth It in 2026?
Function Health is worth it for a specific type of buyer: someone who has never had a comprehensive lab panel, wants a guided experience with a clean interface, and values having all of their results in one longitudinal record. For that person, the $499 is reasonable. A standalone metabolic panel, thyroid panel, complete blood count, lipid panel with ApoB, hormone panel, and iron studies at Quest or Labcorp cash pay would run anywhere from $350 to $700 depending on the tests and whether you use a third-party ordering service. Function’s bundle pricing holds up reasonably well against that if you would actually order all of those tests anyway.
Where the value calculation breaks down is for the member who joins expecting two draws per year, uses only the core panel, and wants to talk to a physician for more than a few minutes. Function’s physician review is asynchronous and message-based. It is useful for flagging concerning results and suggesting follow-up, but it is not a clinical consultation. Members who want a real conversation about their numbers need to bring those results to their own doctor or pay for a separate concierge service.
The honest answer to “is Function Health worth it in 2026” is: yes, for someone entering comprehensive testing for the first time. Probably not for someone who already manages their labs actively and wants the cheapest way to get the same biomarkers covered.

Function Health vs Superpower in 2026: The Key Differences
This is the comparison that comes up most often in 2026 reviews, because Superpower entered the market with a sharply lower price point and has been expanding its panel. Here is where they actually differ:
| Factor | Function Health | Superpower |
|---|---|---|
| Annual price | ~$499/year | ~$199/year |
| Biomarkers covered | 100+ (base panel) | 100+ (base panel) |
| Draws per year | 2 | 1 to 2 depending on plan |
| Physician review | Included (async messaging) | Included (doctor reviews results) |
| Lab network | Quest Diagnostics | Quest Diagnostics |
| HSA/FSA eligible | Partial (varies) | Yes |
| Add-on test costs | $49 to $149 per test | Varies by test |
| Year-over-year tracking | Yes, built-in trending | Yes, longitudinal record |
The $300 annual price gap is the headline number, but the more important question is whether Function’s two-draw structure and more established platform justify that premium. For most people getting a baseline in their 30s or 40s, one thorough annual draw captures the picture that matters. The second Function draw is useful for monitoring after a dietary or medication intervention, but a large share of members report never scheduling their second draw. That means they are paying $499 for what functions, in practice, as a single annual panel. At that point the value comparison becomes stark.

The simplest way to actually get this done
Superpower is a full-body lab membership that runs 100+ biomarkers, has each result reviewed by a doctor, and tracks your numbers year over year (about $199/year). It is what we point readers to when they would rather get one clean, complete draw than chase single tests one at a time. Here is superpower reviewed in full.
What the Negative Reviews Get Right (and Wrong)
The most substantive negative Function Health reviews in 2026 center on two legitimate gripes and one misplaced expectation. The legitimate gripes: the price increase happened without a proportional expansion in what the base membership delivers, and the add-on structure means the advertised price is not the full-cost picture for members who need more than the core panel.
The misplaced expectation: a meaningful fraction of one-star reviews express frustration that Function is not a primary care replacement. It was never designed to be. The platform does not prescribe, does not handle acute illness, and does not loop into your insurance. Members who signed up expecting their $499 to substitute for a relationship with a physician are going to be disappointed, and those reviews should be read with that context in mind.
One nuance worth flagging: some negative reviews mention slow result turnaround times. Quest Diagnostics processes the samples, and turnaround is typically 5 to 10 business days. That is standard for comprehensive panels. Members expecting 24- to 48-hour turnaround the way they might get from a finger-prick at-home kit are comparing different things. Function’s panel requires a full venipuncture draw, which means the same lab pipeline that handles your hospital’s bloodwork.

Function Health New Features in 2026: What Actually Changed
The most notable platform addition in the 2025 to 2026 cycle is the improved trend visualization layer. Earlier versions of the Function dashboard showed individual results with reference ranges but did not do much to surface change over time. The current interface plots longitudinal trends across draws and flags biomarkers that are moving in a concerning direction even if they have not yet crossed outside the standard reference range.
That last point matters more than it sounds. A TSH that moves from 1.2 to 3.8 mIU/L across three annual draws is still technically within the 0.5 to 4.5 normal range on most lab reports, but the trend is clinically meaningful. Function’s current platform surfaces that kind of directional change in a way the old interface did not. That is a genuine improvement in clinical utility, and it is the kind of feature that longitudinal members benefit from far more than first-time users.
The company also rolled out a more structured onboarding flow that helps members understand what their results mean before the physician review message arrives. This reduced one of the more common early complaints, which was that members received a dashboard full of numbers with no context while waiting for the physician note.
How Function Health Results Compare to Your Doctor’s Annual Labs
A standard primary care annual physical in the US typically includes a complete blood count, basic or comprehensive metabolic panel, fasting lipids, and TSH. That covers maybe 20 to 30 data points. Function’s base panel covers more than 100 biomarkers, adding in hormonal panels (testosterone, DHEA-S, estradiol, progesterone depending on sex), inflammatory markers (hsCRP, homocysteine, ferritin), cardiovascular risk markers (ApoB, Lp(a), VLDL), nutrient status (vitamin D, B12, magnesium, zinc), and metabolic markers that go beyond a basic CMP.
The practical upshot: Function’s panel will catch things your annual physical routinely misses. Low vitamin D, subclinical thyroid dysfunction, trending ApoB elevation before LDL becomes abnormal, or early iron dysregulation. Whether catching those things leads to meaningful action depends on whether you have a clinician who will act on them. Function can identify the signal; you still need a qualified practitioner to interpret it in the context of your full clinical picture.
The accuracy question gets its own dedicated answer in our are function health results accurate explainer, but the short version: Function uses Quest Diagnostics, the same CLIA-certified lab that processes your hospital’s bloodwork. The accuracy of the tests themselves is not a meaningful concern. The question is always interpretation, not precision.
Who Should Skip Function Health in 2026
Three groups should probably look elsewhere. First, people who are already active lab managers. If you already order your own panels through a service like Ulta Lab Tests or Walk-In Lab, you know how to read results, and you have a clinician who interprets them, you are not going to get $499 worth of value from a platform whose main contribution is the guided experience and dashboard.
Second, people on tight budgets who need only a targeted panel. If your actual clinical question is narrow, for example you want to check thyroid function and iron because you have fatigue, a targeted draw through your primary care or a cash-pay urgent care will cost $80 to $150 and answer the question directly. Function is designed for people who want the full picture, not a specific diagnostic workup.
Third, people outside Quest’s draw network. Function’s phlebotomy access runs through Quest patient service centers. In most US metros, that is fine. In rural areas or regions with limited Quest coverage, members have reported difficulty scheduling draws, which is one of the more underreported pain points in negative reviews.
A Framework for Judging Any Lab-Testing Membership
Reviews tell you what other people experienced, but they cannot tell you whether a service fits your situation. Use a short checklist to evaluate any comprehensive testing membership, including Function, against your own needs rather than someone else’s star rating.
- Marginal value over your current care. Ask what the membership tests that your existing annual physical does not. If your doctor already runs a lipid panel with ApoB, a full thyroid panel, and metabolic markers, the incremental biomarkers may be smaller than the price suggests. If your annual visit is a basic metabolic panel and a lipid panel, the added coverage is substantial.
- Actionability. A result is only worth paying for if someone acts on it. Confirm you have a clinician who will review out-of-range or trending values with you. A dashboard full of flags with no follow-up plan is an expensive source of anxiety.
- True annual cost. Add the base membership, the add-on tests you realistically need, and any repeat draws. The advertised headline price is rarely the number you actually spend.
- Draw access. Check that a patient service center in the required lab network sits within a reasonable distance. This is the single most common practical failure point, and it does not show up until after you have paid.
- Data portability. Confirm you can export your results as a PDF or structured file to share with any physician. Your biomarker history is a long-term asset; it should not be locked inside one company’s app.
Run any service, Function included, through those five questions and the worth-it decision becomes far clearer than an aggregate rating can make it.
Cancellation, Refunds, and Autorenewal Realities
A recurring theme in critical reviews across the entire category, not just one brand, is surprise at autorenewal. Comprehensive testing memberships typically bill annually and renew automatically unless you cancel before the renewal date. Members who signed up during a promotional first-year price and forgot to note the renewal date sometimes report being charged the full standard rate a year later. Before enrolling in any annual membership, set a calendar reminder two to three weeks before the renewal date so you can decide deliberately rather than by default.
Refund policies for testing memberships are generally limited once a draw has been completed, because the lab has already incurred processing costs. If you have paid but not yet used your draw, you often have more flexibility. Read the specific refund terms before enrolling rather than assuming a standard money-back window applies. If a review complains about being denied a refund, check whether the member had already used the service; that context usually explains the outcome.
What to Actually Do After You Get Your Results
The mistake that undermines the value of any panel is treating the report as the endpoint. The report is the starting point. Once your results arrive, take three concrete steps. First, download and save the full PDF so you have a permanent record independent of the app. Second, identify not just the flagged values but any markers trending in a concerning direction across draws, because directional change inside the normal range is often the earliest useful signal. Third, book a short appointment with a clinician who knows your history and bring the full report, not a screenshot of the flags.
Prioritize your questions before that appointment. If several markers are out of range, ask which one your clinician considers most clinically significant and what the recommended follow-up is, whether that is a repeat test, a lifestyle change, or a referral. A panel that catches an early problem is only valuable if it changes what you do next. Testing without follow-through is the most expensive way to feel informed while changing nothing.

FAQ
Is Function Health worth it in 2026?
For a first-time comprehensive panel buyer who wants a guided experience and longitudinal tracking, yes. For someone already managing their labs actively, the $499 price is hard to justify when alternatives like Superpower cover comparable biomarker counts for about $199. The main thing Function delivers that justifies the higher price is the two-draw structure and a more established platform history.
What do most Function Health reviews say in 2026?
Aggregate ratings hover between 4.2 and 4.6 out of 5. Positive reviews consistently praise the panel breadth, dashboard design, and convenience of the Quest phlebotomy network. Critical reviews focus on the price increase, add-on costs, and the asynchronous rather than real-time nature of physician communication.
Did Function Health raise its price?
Yes. The membership moved to approximately $499 per year during 2025, up from earlier pricing closer to $399. The company did not widely publicize the change, and some reviews from members who renewed on autopay note surprise at the new rate. For a full breakdown of what you are paying for, see our function health cost page.
How does Function Health compare to Superpower in 2026?
Both run 100+ biomarker panels through Quest Diagnostics with physician review included. Function costs about $499 per year and offers two draws. Superpower costs about $199 per year. The $300 price gap is the primary differentiator for most buyers. Superpower’s lower price point makes it the more practical entry point for the majority of members who are not doing back-to-back intervention monitoring that benefits from a mid-year draw.
Are Function Health test results accurate?
Function Health uses Quest Diagnostics, a CLIA-certified national reference laboratory. The analytical accuracy of the tests is the same as what you would get from any Quest draw ordered by your physician. Accuracy concerns in member reviews almost always reflect disagreement about interpretation or reference range framing, not laboratory error. See our dedicated page on are function health results accurate for the full technical explanation.
What are Function Health’s new features in 2026?
The most significant additions are improved longitudinal trend visualization and a more structured onboarding flow that helps members contextualize results before the physician review arrives. The trend tool is particularly useful for catching directional biomarker changes that stay within normal ranges but signal early dysfunction. These updates improve the platform’s utility for returning members more than for first-time users.
Can you use HSA or FSA funds for Function Health?
This is a gray area that varies by plan administrator. Diagnostic lab testing is generally an eligible HSA/FSA expense, but membership-based wellness platforms are sometimes classified as ineligible. Function advises members to check with their plan administrator. Superpower explicitly supports HSA/FSA payment and has documentation to support reimbursement claims, which is a practical advantage for members with those accounts. For more detail, see how much Superpower costs on our how much does superpower cost page.
What do negative Function Health reviews say?
The most common legitimate complaints are the price increase, add-on test costs that push the real annual spend above $700, and the asynchronous physician communication model. The most common misplaced complaint is that Function is not a primary care replacement, which it was never designed to be. Reviews that factor in those context caveats tend to land at a fair 3.5 to 4 out of 5 rather than the one-star rating the frustration sometimes generates.
