Good technicians; check in a bit unwieldy. Clean, good location; but parking is tight.

Went in as a walk-in at 9am on a Friday for a last minute TB test and was worried about a long wait from reading reviews however Joseph took me in before I could even sit and scroll on my phone. He took the sample and I was in and out in a blink of an eye. Highly satisfied with the speed and quality of service!

Good and kind care team. There were a lot of people there, but my appointment was pretty much on time. The staff is friendly. Parking at the Rockledge (Bethesda, MD) location is poor and a fee is charged. Other locations have better parking arrangements.
