I recently started seeing a pain physician for chronic low back pain that had been difficult to manage. On the first visit, he did a urine check, which I supposed was to see if I was compliant with my pain medication. On the second visit, two weeks later, he was dictating his findings in front of me. He told me (off dictation) that I had a low amount of EtG in my urine, briefly explaining that EtG was a metabolite of alcohol. But then he paused and said, "Well, it's a moderate amount." Then he dictated "EtG > 20,000. What does that mean? 20,000 what? 20,000 of anything sounds like a lot and sounds worrisome. Thanks for any help. Lee
