I was wondering if anybody here has taking an Escreen (Ecup) test using Synthetic Urine, or any clean urine. How long did it take for you to get the results....good or bad? I've taken mine 2 weeks ago, and have not heard anything, I've heard that Escreen (ecup) is instant results, and they would call you and let you know with in a day or so if something was wrong with the urine sample.....anybody else used a Escreen test before? If you have, how long did they call you and let you know the results? Good or bad?
