Which sellers we list: only online sellers that run an affiliate program. Other sellers, and free or public options, may cost less and are not compared here. Why and how we earn

Buttons go straight to each seller’s official product page. None of them is a paid link yet; once a seller approves us, its links will be labelled “Paid link” next to the button.

Totals are listed totals: the product price plus required fees shown on the seller’s pages, for this product ordered on its own. They exclude sales tax and optional add-ons and were not confirmed in a checkout. Where a fee can’t be confirmed we show “Check provider price” and leave the offer out of the ranking. How we compare

Who you pay vs. where your sample goes

The seller is the company you pay online. It arranges a clinician’s order and sends you to a collection site run by a lab network, here Quest Diagnostics or Labcorp. Several sellers can send you to the same lab, at different prices. Each offer shows both, and seller profiles explain fees, state limits and refunds.

“No doctor visit” doesn’t mean no clinician: the sellers listed say an independent or in-house clinician orders the test. We don’t interpret results or advise whether you need a test; ask your own clinician.

Questions about cost

Should I compare a B12 test with a B12 and folate panel?

Only if you need both. They are different products, so we compare each with its own kind.
