A certified medical examiner (CME) on the National Registry of Certified Medical Examiners (NRCME) conducts the test.

Fantastic experience from the beginning. Jocelyn was very helpful to me as someone who doesn’t have much experience in needing a test. They were very helpful and walked me through the entire process start to finish. Thank you ADT!

I have used ADT several times. Their phone support has been excellent, both when putting in the orders and when asking for help to interpret results.

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
