How long of a wait will depend on how backed up the lab is. Theres really no "time frame" set in stone.

Do you have a start date secured with the employer?
Burnt Toast Reviewed by Burnt Toast on . Labcorp waiting time frame. It's been about 48 hours since I took my test at labcorp. Followed all the instructions in the dilution thread (avoiding fruit prectin and niacin as it is a bunk). How much longer do you think I will have to wait? my company is using HireRight to conduct the drug screen and background check. The drug screen, was, as I said, through Labcorp. Was 28 days clean. Negative on every at home test I took (which was way to many) Rating: 5
