Took a urine drug screen for pre employment. I figured no problem, been in this scenario before. So I go to the smoke shop and get the synthetic urine that worked for me in the past(XTREME). I go to the clinic, go to the bathroom and come out and hand them my sample. In the past they used tell me on the spot that I passed or inconclusive (meaning failed), it just takes them a day or two to find out exactly what illegal drug is in your system when it comes back inconclusive. Well this time my sample went right the cup, into a zip lock bag and off to the lab and was told that results will be back I couple of days. Two days later the lab calls me and asks if I tampered with the sample. They told me the PH in the urine wasn't consistent with human urine and told me to re- test , THIS TIME DIRECTLY OBSERVED! So my question now is, will this QUIK FIX pLUS get the job done? I'd like to hear from actual experiences please
