Other causes of failed PEth test for alcohol abuse?
My daughter undergoes periodic peth testing for alchohol abuse. She fails regularly, although swears she drinks NOTHING. We have reason to believe she is telling the truth. Assuming she is indeed not drinking, is there a physical condition or ailment that might produce positive peth tests? She is 29, has enlarged lymph nodes, some kind of mysterious condition that gives her severe hives, etc. We are wondering if some type of autoinflammation or autoimmune condition might explain elevated levels. Our daughter is FINALLY discussing this with her regular doctor but if it is some unusual condition a specialist will be needed. The reason the peth test is required is due to a nasty custody dispute with lots of allegations of misconduct. I just want to know if there is ANYTHING other than alchohol consumption that can lead to positive test results. Any thoughts or knowledge of cases? Thanks for reading.

Can several blood transfusions leave you with a raised PEth test ?
Welcome @creigstad,
According to this study "Validation of blood phosphatidylethanol as an alcohol consumption biomarker in patients with chronic liver disease" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4409698/, blood transfusion could potentially affect the results of PEth testing.
See this excerpt:
"Large volume blood transfusions could result in false positive or false negative results for PEth testing, as may have been the case for one of our study participants. It is important to note that this was not necessarily a representative sample of patients with liver disease, as recruitment was completed in a regional referral center for liver diseases."
You may wish to discuss with your medical team.
Question on PEth test I found this test on a July 2022 lab report done on me. I had never heard of it it says PEth- Mayo and my result is high at 25. In looking this up it appears to be a test for alcohol. I rarely drink. I have both an underlying Liver issue Alpha -1 that is genetic and have been diagnosed with Nash-2. My liver enzymes are normal. I come from a diabetic family but am not diabetic. What’s up with this test?
It means absolutely nothing. If the test is accurate, sometime in the last month you probably drank some… that’s it.
It’s a horrible test, well known for false positives and false negatives. Has ZERO diagnostic value of ANY sort on its own.
