Good afternoon - I have been trying to find out how I have one PEth test that shows positive for alcohol when I have not had a drink in over a year. Here is the funny part - at the same time as the PEth test, I also took a urine test which was negative, a hair test which was also negative and was wearing a SCRAM ankle monitor which has never been positive, no tampering, etc. I took the PEth test in early December of 2021 and had the SCRAM monitor on since June of 2021 and there was never a positive reading. I had another PEth test done that showed negative. However, on this one particular PEth test, it shows this astronomical number of 613 which is crazy as I have not had any alcohol. I do have endometriosis and diverticulitis. I have a lot of intestinal and GI issues and things like that, so I am wondering if that could have done it. Every other test was negative plus I have on an ankle monitor.

Just as a note - this was done for a professional evaluation.

Thank you for any assistance.
