TestWell prices are live from the catalog and are what checkout charges. Labcorp OnDemand prices were read from its public ordering pages on 2026-10-21; 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 (80053), 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?
Both companies price this test all-in. TestWell's $28.99 reflects direct-to-consumer pricing negotiated with the labs and a single $6.00 lab fee per order, with physician authorization included; Labcorp OnDemand's $49.00 reflects its own model and overhead.
When is Labcorp OnDemand the better choice?
- Same lab — same Labcorp locations, same Labcorp infrastructure on the backend
- First-party brand familiarity
- Some specialty Labcorp-exclusive panels aren't in TestWell's catalog yet
- 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.
