Does diluted urine for a drug test have anything to do with medical issues or the way you live your every day life? And if so how and why? I took the exam twice and got the same results. I recently accepted a job offer in my area. They required a urine drug test. I took it the first time and it came back dilluted and i took it the second time and it was dilluted again. I was denied the job offer since the company policy is to only take it twice. The 1st time i drank q carbo and tons of water ... and the second time i only drank the q carbo and then took it first thing in the morning. I use marijuana and other drugs occassionaly but had not used in days ( before the test ) ... i even bought a home test kit and came up negative for everything. I take medication aderoll and vikin but have prescriptions for both and i only take when needed. Overall im a healthy person drink tons of water everyday regardless of a urine test or not... and pee at least 10 - 15 times a day or once every hour. Not sure if there is a medical explanation for this but its driving me nuts not knowing what i did wrong ... if its my body or if its the q carbo. Somebody please help !?
