Function Health Alternatives: An Honest Look at Your Options
Competitor facts checked against public sources in September 2026. Hedged where a claim could not be verified.
Function Health is one of the best-known names in consumer lab testing: a $365 annual membership that bundles a large blood panel, a mid-year retest, and clinician review. For people who need a test ordered and interpreted, that bundle is the point of the product.
But a lot of people searching for a Function Health alternative already have results in hand — from their doctor, an employer screening, or a previous direct-to-consumer panel. Paying $365 a year for new draws makes less sense when what you actually need is help understanding and tracking the reports you already own. That is the gap bring-your-own-labs apps, including ByoMap, are built for.
This page compares the two approaches honestly, including where Function Health genuinely wins. Prices and product details were checked against Function Health's public pages in September 2026.
Function Health at a glance
- Price
- $365/year, billed annually (as of Sep 2026)
- Price notes
- Reduced from $499 in November 2025. MRI, CT, and multi-cancer screening are optional add-ons at extra cost.
- Testing model
- Annual membership with two included testing rounds: 100+ tests initially, plus a 60+ test mid-year retest 3–6 months later. Function markets the combined, partly repeated total as "160+ lab tests annually."
- Marker coverage
- 100+ tests in the first round; 60+ in the mid-year round (some markers repeated)
- Availability
- 2,000+ Quest Diagnostics locations across 48 US states, per Function's FAQ, which excludes Rhode Island, Hawaiʻi, and Puerto Rico. Paid concierge home draws in select areas.
- Uploading existing results
- Function invites members to upload past results and track them over time, but its public pages do not state accepted file formats, supported labs, or marker limits.
- Data export
- A PDF download of completed results is documented. We could not find public documentation of CSV, JSON, or API export as of Sep 2026 — which does not mean it isn't offered.

Where Function Health wins — and where ByoMap wins
Where Function Health wins
- The lab draw is included. Function handles the order, the appointment, and the logistics at 2,000+ Quest locations — a bring-your-own-labs app cannot replace that care-delivery layer.
- Clinician review is built in: results are interpreted against your health history, with explanations and action items.
- The included initial and mid-year panels follow a consistent collection protocol, reducing the variation you get from different labs and different test choices.
- Members can add imaging and extended diagnostics (MRI, CT, multi-cancer screening) from the same account, at extra cost.
Where ByoMap wins
- No membership required to understand a report you already own — ByoMap is free during beta.
- Works with the reports you already have, from any provider, instead of requiring a new panel on a set schedule.
- Parses 200+ biomarkers and trends every one of them across all your historical uploads.
- Not limited to the US — useful wherever you can get a blood test done locally.
What ByoMap doesn't do
- ByoMap does not order tests. If you need a blood draw arranged, you need a testing service, your doctor, or a local lab.
- No clinician review or diagnosis. ByoMap is educational and is not a substitute for medical advice.
- No imaging, prescriptions, or supplement marketplace.
Which one is right for you?
Choose Function Health if…
- You need a comprehensive blood test ordered and drawn for you in the US
- You want clinician review and a personalised protocol included
- You want access to add-on imaging like MRI or multi-cancer screening
- You value a standardised panel retested on a fixed schedule
Choose ByoMap if…
- You already have blood test results and want to understand them
- You get tested through your doctor, employer, or a local lab and want everything trended in one place
- You live outside the US, where testing memberships generally don't operate
- You're not ready to commit $365/year before seeing value
Frequently asked questions
Is ByoMap a replacement for Function Health?
No, and it isn't trying to be. Function Health is a testing membership: it orders your labs, arranges the draw, and includes clinician review. ByoMap is a lab-report tracking app for results you already have. If you need a test ordered, ByoMap can't do that — if you already hold reports, ByoMap helps you understand and track them without a $365/year membership.
How much does Function Health cost?
Function Health lists one core membership at $365 per year, billed annually, as of September 2026. The company reduced the price from $499 in November 2025. Add-ons such as MRI, CT, and multi-cancer screening cost extra.
What does Function Health's "160+ lab tests" actually mean?
Per Function's own how-it-works page, the membership year contains two testing rounds: 100+ tests initially, then a 60+ test retest 3–6 months later. Some markers are measured in both rounds, so the combined 160+ figure partly counts repeated tests.
Can I upload my existing blood test results to Function Health?
Function's FAQ says members can upload past results and track them over time. However, its public pages do not state which file formats are accepted, which labs are supported, or whether marker limits apply — so we can't verify how complete that upload experience is as of September 2026.
Is Function Health available outside the US?
Based on Function's public FAQ as of September 2026, no international service is documented. It operates at 2,000+ Quest locations in 48 US states, excluding Rhode Island, Hawaiʻi, and Puerto Rico. If you're outside the US, a bring-your-own-labs app like ByoMap works with reports from local labs.
Do I need a paid membership just to understand an old lab report?
No. ByoMap lets you upload an existing blood report and see your markers against optimal ranges — free during beta, with no annual commitment.
Already have a blood report?
Upload it to ByoMap and see 200+ biomarkers against optimal ranges tuned to your age, sex, and ancestry. Free during beta — no membership, no new draw required.
