I recently took a pre employment UA drug test and used QF 5.7 canadian version. The doctor called me back and told me it came back as synthetic urine. I am going to get the results from him on Monday and will definitely report back. I'm in the state of Washington and had my sample sent to PacLabs out of the Seattle area. Any one know anything about this? Only seen a few similar accounts, on a message board and about some UFC fighter getting results declaring his sample "inconsistent with human urine", just as I was told about my own sample. Does anyone have some good info out there? I'm just trying to find out what happened with mine and prevent others from being embarrassed.
