Let me ease the worries of anyone taking a standard pre employment 5 panel urine test at LABCORP using quick fix 5.7. i took it an passed! As long as you get the temperature within 90-100 degrees you will have no problems. I was freaking out before, during, and after... but let me tell you quick fix is your only guarantee to passing a urine test at Labcorp if you think your pee will be dirty. Don't trust diluting, and don't trust these detox drinks (unless you have a couple of weeks to really clean out your system before the test). Good luck to all that have to go through what I just went through. Thank g-d it is over, and thank g-d for quick fix.
