At quest was the first ever through blood draw and sent out and 8 days later was shands hospital lab done through blood draw both were done in the afternoon about 1-2:00pm if I remember correctly. We knew the first would be positive as he had a few drinks 2 nights before (long story but was told he could because they had him in the wrong group) but the second one should have been negative as he had no more alcohol at all ever after the one night and they are saying and not listing him because they say he is continuing to drink

We were told that the PEth test could be positive up to 9 days from last drink. We faught Vanderbilt bc my husband had not had a drink since 2019. This test is unreliable and has plenty of false positives, but some egotistical physicians do not want to accept that. There is also research on if the specimen is left out in certain room temps, is old. They need to take it case by case holistic approach to each pt. I even called the lab and the lab stated hx of false positives had occurred and doctor would not accept. We changed hospitals and doctors and received a transplant
