Usually the wait is less than 15 min. for a blood draw. I go in the middle of the day between noon-3pm. Depending on which tech you get, you may be blamed for the tech's inability to draw blood out of your vein. That gets so annoying! If my doctor (who NEVER has had a problem getting my vein for a blood draw or weekly IV) didn't have his office way in north Scottsdale I'd have him draw my blood (since I have to do so weekly for the treatment I'm under). Only because this Labcorp is super convenient in locale, and the wait is quite short, I keep going. But if I find some place better that's closer, I'm jumping this ship.
