Are TestWell and Walk-In Lab using the same labs?

When the lab partner is the same (Quest or Labcorp), the actual analysis is identical — same machines, same reference ranges, same CLIA-certified facility. The differences are price, ordering experience, and what's included.

Can I switch from Walk-In Lab to TestWell mid-year?

Yes. Lab tests aren't subscriptions you have to cancel — each order stands alone. If you've already paid for a year of Walk-In Lab, use what you've paid for, and order any additional tests through TestWell.

Will my doctor accept TestWell results?

Yes. Your results are CLIA-certified lab results from Quest or Labcorp — the same labs your doctor uses. You can download a PDF and bring it to any provider.

Is Walk-In Lab the same as TestWell?

Both companies are DTC lab marketplaces that route orders through Quest Diagnostics and Labcorp, so the underlying lab work is identical. Walk-In Lab has a larger raw catalog (1,000+ SKUs) and has been around since 2007. TestWell is more curated, faster on comprehensive panels, and adds modern conveniences like an AI Lab Agent that helps you choose the right test, condition-specific bundles, and a provider portal for clinicians.

When is TestWell a better choice than Walk-In Lab?

Three situations. First, when you want a curated experience instead of browsing a 1,000-SKU catalog. Second, when you need a comprehensive panel — our Total Body and condition-specific panels are typically faster (1-3 day turnaround vs. Walk-In Lab's 7-8 days for their comparable PPP Wellness panels) and bundle markers more cleanly. Third, when you want help picking the right test — our Lab Agent walks you through it and Walk-In Lab leaves you to figure it out alone.

•Provider portal — clinicians can recommend tests to patients in one click
