Why you can trust JustLabs
Real Quest Diagnostics labs
Your blood is drawn at a Quest Diagnostics patient service center (Sonora Quest in Arizona) and run by Quest’s CLIA-certified labs: the same Quest labs many doctors order from.
An independent physician orders every test
Every order is reviewed and authorized by an independent physician, so no doctor visit is needed. That order is covered by the one fee.
Private and HIPAA-aware
Results live in your private account, and our analytics never see which tests you bought.
Secure checkout, HSA/FSA accepted
Pay by card through Stripe; HSA/FSA cards work and every order has an itemized receipt.
Refunds before your draw
Cancel an unused order within 21 days for a refund, less a $15 cancellation fee. Once your sample is collected the order can’t be refunded.
A registered US company
JustLabs is operated by Butterfly Technologies, Inc.
