Questions people in Phoenix ask us

Every one of these gets asked on the phone daily. No judgment, just answers.

Do I need an appointment?
No. Order online first so your lab order is in the system, then walk in during the test center's business hours and sign in. The visit itself usually takes about five minutes.
How fast will I get results?
Most tests post to your secure online account in usually 1-2 business days. Rapid drug screens are read at the collection site the same day. Specialty and DNA tests take longer - each product page tells you before you buy.
What does "all-in" pricing mean?
The price you see is the price you pay. No draw fees, no physician fees, no surprise bills. Competitors advertise one number and add fees at checkout - we don't.
Is this confidential?
Completely. You order online, nobody calls your home, nothing arrives in the mail, and results go only to your password-protected account. You decide who sees them - including whether your own doctor does.
How do I know which test I need?
Start with what's going on: a symptom, a request from a doctor or employer, or just wanting answers. Each category page walks you through it - and if you'd rather talk it through, our Care Advisors do this all day at (866) 873-0879.
Do Phoenix test centers serve the whole valley?
Between Phoenix's ten centers and the Mesa, Scottsdale, Glendale and Peoria locations, most of the metro is within fifteen minutes of a draw chair. Your electronic order works at any center, so pick by traffic, not by what you clicked first.
