How does the lab visit work?

  1. 1. Order online

    Pick your tests, check out, and a licensed physician authorizes the requisition — usually within minutes. You choose Quest or Labcorp at checkout outside NY/NJ.

  2. 2. Walk in with the requisition

    Use the finder above to pick a site, bring a photo ID, and show the emailed requisition. No insurance card, no payment at the desk — the price you paid is all-in.

  3. 3. Results in 1–3 business days

    Each test posts to your TestWell portal as the lab finishes it, with reference ranges and plain-English explanations, and you get an email the moment they land.

Which lab runs your test in each state?

In 47 states you choose Quest Diagnostics or Labcorp at checkout. New York and New Jersey route to BioReference under state licensing rules, and Rhode Island isn't served yet. Each state page lists major-metro coverage and state-specific ordering notes.
