I called him and he explained. He was worried about an upcoming court date. Why? He was subject to urine testing at a probation/parole office. The last 4 tests had been positive for alcohol. But he hadn’t been drinking. 2/13

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
