Had previously used this location three times in the past with satisfactory wait times but was unaware that LabCorp had recently established an appointment system. I came in at 8:00 AM and signed in on the roster noting that the estimated waiting time was one hour which was acceptable. I also noted that there were already about thirty people in the waiting area seated and waiting. After waiting for an hour and a half seeing people coming in after me being called into the lab, I went to the receptionist and asked where I was on the waiting list. She replied, "I've been busy processing patients with APPOINTMENTS FIRST." I was furious to learn that "drop ins" would be processed AFTER those with appointments were admitted first, time permitting. Had I been told that is the current practice for "drop ins" up front, I would never have signed in. The complete lack of consideration of my time was totally unacceptable! My advice to anyone needing lab work from LabCorp is to MAKE AN APPOINTMENT! If I could rate this location with no stars I would do so as it is certainly what it deserves.
