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.

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 had no problems when I called to get connected with welcare everything worked out and I didn't even have to wait.they were polite and talked with the receptionist for me once I got them on the phone.

It was easy to make the arrangements to get to someone in regards to renewing my DOT medical certificate. They took care of everything over the phone which made my experience hassle free. I will definitely be using them again and you should too.

I am just really happy to see that the location near me still offers hair follicle tests!! They are really helpful when any false positives happen, waiting on my results. Hope they come fast!
