I read all the reviews here complaining about long wait times at various LabCorp locations. Well I decided to book an appointment online with LabCorp online appointment scheduling system and received a confirmation number. Instead of going there in the morning like I wanted, I had to wait a few extra days for the next available morning appointment.
My appointment was at 8:45 AM and I arrived on time. They took me in right away and got my blood drawn for lab work. I was out of there shortly. The other people were pissed because they said they waited before me, "claimed" they had an appointment but when the receptionist checked, she said, ""You don't have an appointment." So it's first come, first serve for them. Not sure if they completed made up they had an appointment, had someone "book" it through some unknown system, etc.
Planning and appointments work .. in life, in general. Save yourself time and headache by booking appointments and organizing yourself. Life will be easier.
