I took the test a clinic called labcorp today using the Herbal Clean Q Carbo Clear 20. Before the test i did not eat anything only fallowed the directions on the bottle. Before leaving my house i used the restroom like six time and my urine was clear before i left the house. The clinic was only one mile a way from my house so i walk there and back along the way i use the restroom three more times and my urine was still clear. When i got to the Labcorp Clinic and i was asked for a urine sample. So i went into the restroom and i urinated into the cup and it was a light yellow color then. I took the sample back to the nurse and she split it into two cups, one to be tested and the other sample they keep if i disagree with the first they will use the other sample for testing. They said it would take one to two days for me to hear my results from the test if i passed or not. I will post my final results as soon as i know i hope that this information helps.
