I just substituted a pre-employment test for Concentra. I took the test Friday April 10th, and the following Friday, the 19th, the company I applied to, wanted to know which office I took the urine not received the results which they said "concerned them."

I had to add maybe a tbsp. of my own sample to the substituted sample because I did not have enough, but I diluted like mad that day.


Should I be shitting bricks?
