Hemoglobin A1c test price: TestWell vs Function Health
Short answer
A Hemoglobin A1c test costs $27.99 all-in at TestWell versus $365.00 at Function Health — $337.01 (92%) less as of 2026-09-05. Function Health's figure is the effective price inside a $365/year membership; TestWell's $21.99 plus the single $6.00 lab fee is the whole price with no membership. The blood is analyzed at the same lab, so the result is the same test.

TestWell prices are live from the catalog and are what checkout charges. Function Health prices were read from its public ordering pages on 2026-09-05; all-in assumes one test ordered alone.
Is it the same test?
Yes. Both orders are analyzed at the same CLIA-certified lab under the same CPT code (83036), so the assay, the reference range and the number on your report are identical. You are paying for the ordering experience, the physician authorization and any bundling — not a different test.
Where does the price difference come from?
Function Health sells testing as a $365-a-year membership, so its per-test figure only holds if you use the full program. TestWell charges per test — $21.99 plus one $6.00 lab fee per order — which is why a single Hemoglobin A1c test is $27.99 with nothing else to buy.
When is Function Health the better choice?
- At $365 for 160+ tests drawn twice a year, the per-marker price is far below any à-la-carte option — if you will actually use both draws
- Clinician review with written insights on every result — TestWell's physician review authorizes the order, it isn't a consult
- Strong brand around longevity and whole-body testing; MRI/CT and Galleri add-ons
- You want a clinician consult included. A licensed physician authorizes every TestWell order, but that review is not a visit — there is no call to walk through results unless you bring them to your own provider.
- You can't get to a draw site. TestWell is venous-draw only at Quest, Labcorp and BioReference locations; we don't ship at-home finger-prick kits.
