Obviously, this was unusual. And puzzling. This guy had been on the right track; we had just made so much progress with his diabetes. What was going on? I had him come to our lab. There, his urine had no alcohol in it, and no ethyl glucuronide (an alcohol metabolite). 3/13

I called the parole office and spoke to the person in charge or urine collections. I asked: Did they test the urine on site? “No.” How often did they send the urine off to a lab for testing? “Once a day.” Did they refrigerate the urine prior to transport? “No.” 4/13
