How long before the results of urine test get back to company?

It was at a hospital , the company called me back today to set up orientation for monday, so was not sure if they got the results back? I know they would not have called to set the orientation up if i failed cuz that would just cost more money, i was just wondering if any one took one and knew within how many days they had taken it if they passed/failedit was greens only and maybe three hits if even that, i was at a party, i dont smoke anymore, it was really stupid, and i know i will never do it again. thanks for any advice/help LOL
