I wanted to pass on this information. I took a Urine Screening last Thursday the 9th of February. The test is part of DISA and is identified as 20239N SAP 9-20 2000 A300. I purchased QuickFix 5.7 with UREA (Uric Acid) and substituted my sample using a Wizzinator. The temperature was between 90-100. Today I received a call from my employer stating that the test came up inconclusive and they are asking me to retest. I have asked for documentation of the results and I will post the documentation to this forum. I currently live in Texas. It looks like the testing facilities are now winning the war, and synthetic urine is no longer an option which is very disappointing because I have passed tests for years using Dr. Johns Famous Pee Pee that didn't have UREA. I'm hoping that having an inconclusive urine sample will not constitute the next Urine Test to be observed. Otherwise I am in a world of hurt, and will be trying my damndest to clean up this weekend (sweat, sweat, sweat, exercise, exercise, exercise, water, water, water) until Sunday when I eat big, be lazy and follow the dilution method.
