my test just ended up being a urine test...I'm still unsure of how I did though, I passed a practice test in the morning that's said to have a detection limit of 50 ng/ml but the test I took was 20 mg/ml

I took the test yesterday at about 2:30 so I doubt they had time to analyze it yesterday. Anyone know how long it takes to find out if I failed? I don't think they would contact me unless I failed...
