Your specimen will be processed at either Quest Diagnostics or LabCorp - both are CLIA-certified national laboratories trusted by doctors and hospitals across the U.S. for accurate, reliable results. 

These labs are not interchangeable.

After checkout, you'll be directed to schedule your specimen collection appointment based on which lab is processing your test: 

• Quest Diagnostics orders: You'll schedule directly on our website after completing your order
• LabCorp orders: We'll provide a booking link right after checkout to schedule at a LabCorp location
