Quest Diagnostics - 250 W Bonita Ave
Great discreet service, scheduled my visit and paid for for the test online not in Showed up at lab, checked in and was seen within minutes. Blood and urine were collected, test results came back quickly within 2 days because I did my test on a Friday. Quick, easy and cheap. Didn't have to wait for a visit to my PCP, and then get referral to lab.

A great experience for something I had a lot of anxiety about. Had no wait time or issues at the testing center/lab. Had blood drawn at 3pm and had results by email at 9am the next morning.
