Yes — the sample is analyzed at the same CLIA-certified lab (CPT 84681), so the assay, reference range and result are identical. What differs is the price, the ordering experience and what else is bundled. ### Are Own Your Labs's prices all-in? Yes, Own Your Labs's sticker is its all-in price for a single test, and so is TestWell's $35.99 ($29.99 plus one $6.00 lab fee per order). ### How current are these prices? TestWell's price is read from the live catalog every time this page loads and is exactly what checkout charges. Own Your Labs's sticker and fees were read from its public ordering pages on 2026-10-12 and are re-verified at least monthly; the same rows power our Blood Test Price Index. ### Do I need a doctor's order for a C-Peptide test? Not at TestWell — a licensed physician in our network reviews and authorizes every order, and the requisition is emailed to you (usually within the hour). Own Your Labs also includes physician authorization in its price. ## Sources - [Own Your Labs public pricing page (1) — verified 2026-10-12](https://ownyourlabs.com/shop) - [Own Your Labs public pricing page (2) — verified 2026-10-12](https://ownyourlabs.com/how-it-works) - [Own Your Labs public pricing page (3) — verified 2026-10-12](https://ownyourlabs.com/faq) - [Own Your Labs public pricing page (4) — verified 2026-10-12](https://ownyourlabs.com/terms-and-conditions) - [TestWell Blood Test Price Index (methodology, CSV/JSON)](https://www.test-well.com/research/blood-test-price-index) - [TestWell C-Peptide — live price and details](https://www.test-well.com/tests/c-peptide-test) --- Canonical page: https://www.test-well.com/compare/own-your-labs/c-peptide-test Machine-readable catalog: https://www.test-well.com/api/catalog.json · MCP server: https://www.test-well.com/mcp · Overview for agents: https://www.test-well.com/llms.txt Prices are cash-pay, in USD, and include physician authorization; every order adds one flat $6 lab processing fee.
