We recently had a female donor come it to our clinic for a urine drug test. She made her first attempt but was unable to produce enough urine to be tested (we need 45ml, about 2 ounces). We gave her a bottle of water and sent her back to the waiting room while we attended to other people testing that day.
She wasn’t there long when she shot up out of her chair with her pants soaking wet and abruptly left the building. Apparently she had a “clean” specimen of urine hidden on herself somewhere and the container it was in broke spilling the urine all over herself.
