Quick answer: Function Health add-on test costs range from roughly $50 to $950 on top of the annual membership fee (currently $499/year). Common add-ons include the Galleri multi-cancer early detection test (around $949), MTHFR genotyping (around $50 to $75), and various advanced hormone or cardiac panels. If you plan to stack more than one or two add-ons, your total out-of-pocket can easily exceed $800 to $1,200 for a single year, which changes the cost-per-biomarker math significantly compared with competitors like Superpower.
How Function Health Add-On Pricing Works
Function Health structures its billing in two layers: a flat annual membership that unlocks the core 100-plus biomarker draw, and a separate a-la-carte menu of add-on tests you purchase individually. The membership itself runs $499/year as of mid-2026. Add-ons are priced individually at checkout and are NOT included in that base fee, which surprises a lot of first-time members who assumed the membership covered everything. There is no bundled add-on tier or “unlimited” upgrade path currently available.
Payment for add-ons runs through the same account portal. Most add-ons are drawn at the same Quest Diagnostics or Labcorp appointment as your annual panel, so you are not scheduling a second visit. A few specialized tests (notably Galleri) require a separate blood collection kit or a dedicated draw appointment, which matters if you are time-sensitive.
Function Health does not accept insurance for its membership or add-ons. HSA and FSA cards are accepted for most tests because they qualify as diagnostic services, but always confirm with your plan administrator before counting on reimbursement. For a deeper breakdown of the base membership, see our function health cost guide.
Full Add-On Test Price List for 2026
The table below reflects reported member pricing and Function Health public communications as of early 2026. Prices are subject to change; always verify at checkout before purchasing.
| Add-On Test | Reported Price (USD) | What It Measures | Notes |
|---|---|---|---|
| Galleri (multi-cancer signal) | ~$949 | Circulating tumor DNA fragments across 50+ cancer types | Requires separate Grail kit; not a screening replacement for mammogram/colonoscopy |
| MTHFR Genotyping (C677T + A1298C) | ~$50 to $75 | Common methylation gene variants | One-time genetic test; results do not change year over year |
| Advanced Thyroid (TPO + TgAb antibodies) | ~$75 to $120 | Autoimmune thyroid markers beyond standard TSH/Free T4 | Useful if you have Hashimoto’s symptoms or family history |
| Comprehensive Hormone Panel (female) | ~$120 to $200 | Estradiol, progesterone, LH, FSH, DHEA-S, testosterone | Timing in cycle matters; draw window specified in instructions |
| Comprehensive Hormone Panel (male) | ~$100 to $150 | Total + free testosterone, SHBG, LH, FSH, estradiol | Morning draw recommended for accurate testosterone |
| Advanced Cardiovascular (ApoB, Lp(a), sdLDL) | ~$150 to $250 | Atherogenic particle count beyond standard lipid panel | Most useful if base LDL appears normal but you have cardiac risk |
| Heavy Metals Panel | ~$100 to $180 | Lead, mercury, arsenic, cadmium | Often relevant for seafood-heavy diets or occupational exposure |
| Micronutrient Panel (SpectraCell or equivalent) | ~$150 to $250 | Intracellular levels of B vitamins, minerals, antioxidants | Different methodology than standard serum micronutrients |
| Food Sensitivity (IgG) | ~$200 to $350 | IgG antibodies to 96 to 200+ foods | Clinical validity is debated; results guide elimination trials, not diagnosis |
| APOE Genotyping (Alzheimer’s risk) | ~$100 to $150 | APOE e4 allele status | Genetic counseling recommended before ordering; results are permanent and psychologically significant |
A few things that table makes clear: the Galleri test alone costs nearly twice the annual membership fee. Stacking Galleri plus an advanced cardiovascular panel plus MTHFR puts a single-year total somewhere between $1,150 and $1,275 before tax. That is a materially different budget decision than the $499 headline suggests.
How Much Does the Galleri Test Cost Through Function Health?
The Galleri multi-cancer early detection test is priced at approximately $949 when ordered through Function Health, which is the same retail price Grail (the manufacturer) charges through most direct channels. Function Health does not currently offer a member discount on Galleri. For context, Grail’s list price through employer wellness programs ranges from $949 to $999, so you are paying market rate.
What you do get by ordering through Function Health is integration into your existing results dashboard and a physician-reviewed interpretation alongside your other biomarkers. That matters: a positive Galleri signal without a clinician walking you through next steps is an anxiety machine. The Function Health workflow at least puts the result in clinical context rather than dropping it in your inbox alone.
Medicare does not cover Galleri as a standalone screening test as of 2026. Commercial insurance coverage is limited to a handful of employer pilot programs. Most members pay cash. HSA/FSA reimbursement is generally eligible because Galleri is a diagnostic assay, but get a letter of medical necessity from a provider if your plan requires documentation.
What Does the MTHFR Test Cost on Function Health?
MTHFR genotyping through Function Health runs approximately $50 to $75 depending on whether you order C677T alone or both the C677T and A1298C variants (the two clinically relevant polymorphisms). This is actually competitive with standalone Quest or Labcorp direct-to-consumer pricing, which runs $60 to $90 for the combined panel.
One important practical note: MTHFR is a one-time test. Your DNA does not change, so ordering it every year inside an annual membership renewal makes zero sense. If you have already had MTHFR tested through 23andMe, your raw data contains those SNPs and you can interpret them yourself without paying again. Function Health’s value here is the clinical context layer, not the assay itself.
The clinical significance of MTHFR variants is also frequently overstated in wellness circles. A heterozygous C677T variant (the most common finding) modestly reduces MTHF production and rarely requires treatment beyond ensuring adequate dietary folate or methylfolate supplementation. Talk to a clinician about your results before making supplement decisions based on a MTHFR positive.
Total Cost Scenarios: What You Actually Spend
The honest way to evaluate function health add on tests cost is to build out a realistic scenario for your actual health goals, not just the membership headline. Here are three representative profiles.
Scenario A: Basic member, no add-ons
- Annual membership: $499
- Core biomarker draw: included
- Total year-one cost: $499
Scenario B: Mid-tier health optimizer (MTHFR + advanced cardiovascular)
- Annual membership: $499
- MTHFR genotyping: ~$65
- Advanced cardiovascular panel (ApoB, Lp(a)): ~$200
- Total year-one cost: ~$764
- Year two (membership renewal, no MTHFR repeat): ~$699
Scenario C: Full optimization with Galleri
- Annual membership: $499
- Galleri: ~$949
- Female hormone panel: ~$150
- Heavy metals: ~$140
- Total year-one cost: ~$1,738
Scenario C is not unusual among the Function Health target customer (high-income, proactive, longevity-focused). But it is worth benchmarking: at $1,738, you are paying more than eight times the cost of a superpower blood test review membership, which includes 100-plus markers with physician review for roughly $199/year. The comparison is not apples-to-apples because Galleri is a specialized oncology screening tool that Superpower does not offer. But if your goal is comprehensive metabolic and hormonal data plus physician review rather than cancer screening, the cost calculus shifts considerably.
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 blood test review reviewed in full.
Are Add-On Costs Covered by Insurance or HSA?
Function Health does not bill insurance for any part of its service, membership or add-ons. That is a structural decision, not a limitation. By operating outside insurance networks, Function Health can offer tests at negotiated lab rates rather than billed-charge rates, which is how they keep some add-on prices competitive with cash-pay Quest/Labcorp direct ordering. For the full picture on insurance, read our piece on does insurance cover function health.
HSA and FSA dollars are generally usable for diagnostic blood tests, including most Function Health add-ons. The MTHFR test, cardiovascular panels, hormone panels, and heavy metals panels almost universally qualify. Food sensitivity IgG tests and some genetic tests (APOE, MTHFR) occupy a gray zone with some HSA administrators. Galleri is generally eligible as a diagnostic assay but some flexible spending plans require a physician letter of medical necessity. When in doubt, call your HSA custodian before ordering.
One practical workaround: if your employer offers an HRA (health reimbursement arrangement), Function Health add-ons may qualify under HRA plan rules, which are set by the employer rather than IRS guidelines alone. This is particularly common at larger tech companies with comprehensive wellness benefits.
How Do Function Health Add-On Prices Compare to Competitors?
The function health cost of add on tests looks different depending on whether you compare to direct-lab pricing, concierge services, or all-in membership models.
| Test | Function Health Add-On | Quest/Labcorp Cash Pay | Superpower (included) | InsideTracker equivalent |
|---|---|---|---|---|
| MTHFR (C677T + A1298C) | ~$65 | $60 to $90 | Not included | Not offered |
| ApoB | Part of ~$200 CV panel | $25 to $50 standalone | Included in base panel | Available ~$60 |
| Lp(a) | Part of ~$200 CV panel | $30 to $60 standalone | Included in base panel | Not always included |
| Free testosterone | Part of hormone panel ~$125 | $50 to $80 standalone | Included in base panel | ~$80 add-on |
| Galleri | ~$949 | ~$949 (Grail direct) | Not offered | Not offered |
The comparison reveals something counterintuitive: for tests like ApoB, Lp(a), and free testosterone, Superpower includes them in its base $199/year membership without any add-on charge. That makes the “apples-to-apples” add-on comparison misleading. You are not really paying $200 extra to get ApoB through Function Health’s cardiovascular add-on; you are also paying the $499 base when those markers come free at Superpower.
Where Function Health genuinely wins on add-ons: the Galleri integration, APOE genotyping, and the food sensitivity panels are not available through Superpower at all. If those specific tests are your priority, Function Health is one of the few membership models that can accommodate them in a single draw framework.
What the Advanced Add-Ons Actually Include
Function Health uses the term “advanced add-ons” loosely in marketing materials, so here is what that category actually contains in practice based on member reporting and the platform’s test catalog as of 2026.
Advanced cardiovascular add-ons
Beyond the base lipid panel (total cholesterol, LDL, HDL, triglycerides), advanced cardiovascular options typically include ApoB, Lp(a), oxidized LDL, sdLDL particle size, and sometimes homocysteine. ApoB and Lp(a) are the two markers cardiologists most commonly call underused in standard care. ApoB tracks the total count of atherogenic particles regardless of size, which is a better predictor of cardiovascular events than LDL-C alone in many patients. Lp(a) is genetically determined and cannot be modified by lifestyle, which makes it less actionable but important for risk stratification. If your Lp(a) is above 50 mg/dL, that information changes your statin conversation with a clinician significantly.
Advanced thyroid and autoimmune add-ons
The base Function Health panel includes TSH, Free T4, and Free T3. Advanced thyroid add-ons add TPO antibodies (anti-thyroid peroxidase) and thyroglobulin antibodies, which are the markers that confirm or rule out Hashimoto’s thyroiditis. Standard care almost never runs these unless a patient presents with symptoms, yet subclinical Hashimoto’s affects roughly 5% of the population. This is one of the genuinely useful add-ons for people with unexplained fatigue, weight changes, or a family history of thyroid disease.
Genetic add-ons (MTHFR, APOE)
These are one-time tests with permanent results. Order them once, not annually. The function health advanced add ons price for genetics tends to be reasonable compared to direct genetic testing services, with the advantage of medical-context interpretation in the same dashboard as your lab work.
When Add-Ons Are Worth It (and When They Are Not)
The clearest case for a Function Health add-on: you already have the membership, you have a specific clinical question (“do I have Hashimoto’s?”, “what is my Lp(a)?”, “do I carry APOE e4?”), and the test is not something you can cheaply access through a PCP order. Adding a $65 MTHFR test or an $80 TPO antibody to an existing draw is genuinely good value in that context.
The weaker case: ordering multiple expensive add-ons primarily because the dashboard makes it easy and the health optimization mindset is compelling. Galleri at $949 is a meaningful screening tool for people with elevated cancer risk (strong family history, prior cancer, age 50+). For a healthy 32-year-old with no risk factors, the pre-test probability is low enough that a positive signal is more likely a false positive than a true positive, and the downstream anxiety and follow-up testing costs can be substantial. Read the Grail clinical data before ordering, not Function Health’s marketing.
Also worth knowing: if you are reconsidering membership entirely after seeing the add-on costs, review the function health cancellation refund policy before you commit to a year. The refund window is limited and membership fees are not prorated in all cases.
FAQ
What is the cheapest Function Health add-on test?
MTHFR genotyping is typically the lowest-cost add-on at around $50 to $75. Individual single-marker add-ons like a specific hormone or antibody test can sometimes fall in a similar range, but the more commonly purchased add-ons (cardiovascular panels, hormone panels) are bundled at $100 to $250. Function Health tends to package related markers together rather than selling individual markers separately.
Does Function Health charge extra for doctor review of add-on results?
No. Physician review and interpretation of all results, including add-ons, is included in the membership fee. You do not pay extra per consultation or per result reviewed. That is one legitimate advantage of the Function Health model over simply ordering tests cash-pay through Quest Direct: you get structured clinical context, not just a number with a reference range.
Can I order Function Health add-ons without the annual membership?
No. Add-ons require an active Function Health membership. You cannot purchase individual add-on tests a-la-carte as a non-member. If your goal is a single specific test (say, Galleri), you can order directly through Grail’s website at the same price without paying Function Health’s $499 membership fee, though you lose the integrated dashboard and physician review.
Is the Function Health Galleri test the same as ordering Galleri directly?
The assay is identical. Grail runs both. The difference is the wrapper: through Function Health, your Galleri result lives alongside 100-plus other biomarkers in one dashboard, and a Function Health physician reviews all results together. Ordering Galleri directly through Grail or a standalone ordering service gives you only the Galleri result with Grail’s own result communication, typically a brief report with a positive or negative signal and a recommendation to follow up with your doctor.
Are Function Health add-on prices negotiable or do they change?
Prices are set by Function Health and are not individually negotiable. They have changed over time and will likely continue to adjust. The Galleri price in particular is subject to Grail’s pricing decisions rather than Function Health’s discretion. Members occasionally report promotional pricing during onboarding or annual renewal, but there is no public coupon program. See our function health review for the full membership experience context.
How do I know which add-ons are worth ordering?
Start with your personal risk profile and clinical gaps. If your core panel shows normal lipids but you have a first-degree relative who had a heart attack before 60, adding ApoB and Lp(a) is medically justified. If you have fatigue that standard thyroid testing has not explained, adding TPO antibodies is reasonable. If you are healthy, under 45, and have no cancer family history, Galleri is probably not a high-yield purchase yet. Talk to a clinician about your results and risk factors before stacking add-ons based on marketing. For a broader cost comparison with alternatives, see how much does superpower cost.
Do Function Health add-ons show up on my medical record?
Function Health operates outside the traditional insurance and EHR system. Your results are stored in Function Health’s platform and are generally not automatically transmitted to your PCP’s electronic health record. If you want your results included in your medical record, you typically need to download and share them manually, or work with a provider who will order a confirmatory test through a standard clinical channel. This privacy-by-default setup is a feature for some members and a limitation for others who want integrated care.
Can I use HSA funds to pay for the Galleri test through Function Health?
Galleri is generally HSA-eligible as a diagnostic blood test, but some HSA administrators require documentation that a licensed clinician recommended the test. Function Health’s physician review process may satisfy this requirement, but request a receipt showing the test name and an order from the medical team before submitting for reimbursement. When in doubt, contact your HSA administrator before purchasing rather than assuming eligibility after the fact.
