What is the difference between Function Health and Bevita?

Function Health is a paid annual membership that orders a large panel of lab tests for you (100+ biomarkers) and presents the results. Bevita is an app that reads and interprets the lab results you already get from your doctor or any lab — you upload the PDF and it tracks trends, calculates derived markers, and ties results to symptoms. Function provides the testing; Bevita makes sense of testing you already do.

Is Function Health worth it?

It depends on whether you want someone to order a broad panel for you and don't mind the annual fee. If you already get regular bloodwork through your doctor or insurance, you may be paying twice — in that case an app that interprets your existing labs is more cost-effective. Function's value is breadth of testing; its cost is the membership.

Can I use Bevita with tests from any lab?

Yes. Bevita is lab-agnostic — you can upload results from your doctor, a hospital, or any testing service, including a Function Health panel. It reads the values and tracks them over time regardless of where the blood was drawn.

Function Health vs Bevita: Which Fits How You Actually Test?

Function Health and Bevita get mentioned in the same breath, but they solve different halves of the problem. One is about getting tested; the other is about understanding the tests you get. Knowing which gap you’re trying to fill makes the choice obvious.

The stat most people don’t know

Most adults already get blood drawn more often than they realize — annual physicals, pre-op panels, pregnancy, chronic-condition monitoring — but the results scatter across portals and PDFs and are never looked at as a trend. So for a lot of people the missing piece isn’t more testing; it’s actually reading the testing they already do. That distinction is the whole comparison.

What Function Health is

Function Health is a paid annual membership that orders a large panel — 100+ biomarkers — through partner labs, then shows you the results in a dashboard with clinician review. Its pitch is breadth: one big draw covering far more markers than a typical checkup.

Strength: comprehensive testing you might not otherwise get ordered.
Cost: an annual fee, on top of any testing you already receive through insurance or your doctor.
Model: it’s a testing service first, with a results interface attached.

What Bevita is

Bevita is an app that reads the labs you already have. You upload a PDF from your doctor, hospital, or any lab, and it interprets and tracks them.

Strength: turns existing, scattered results into a readable trend — plus calculated markers and symptom connections.
Cost: free to start; no test-kit fees because it doesn’t sell tests.
Model: interpretation first — it’s lab-agnostic and works with whatever bloodwork you get, including a Function panel.

Where they overlap and where they don’t

Getting a broad panel ordered: Function does this; Bevita doesn’t order tests.
Reading results over time: both show trends, but Bevita focuses on derived markers (like HOMA-IR for insulin resistance), optimal-vs-normal flags, and tying labs to symptoms like fatigue or brain fog.
Cost structure: Function is a recurring membership; Bevita is free to start and works with tests you already pay for elsewhere.

What this looks like in Bevita

Whatever panel you run — your doctor’s or a Function membership’s — this is what Bevita does with it. On this “Overall picture” screen it calculates markers that aren’t on the original report (HOMA-IR 2.02, beta-cell function 126.6%), interprets them in plain English (“suggests early insulin resistance”), and surfaces what needs attention. Upload the PDF; it does the reading.

The bottom line

Choose Function Health if you want a broad panel ordered for you and the annual fee fits your budget.
Choose Bevita if you already get bloodwork and want it actually read, tracked, and connected to how you feel — for free, from any lab.
Or both: run a Function panel, then upload it to Bevita to track those markers over time alongside every future test.
