I had to be have a drug test, I was told after the test that I tested negative for alcohol, drugs etc, although I had had a couple of beers at a restaurant the night before and it was at least 18 hours prior to the test. I knew I was going to be positive for the test for alcohol use they where using a test that would tell me if I had a drink within 80 hours. I did some research and found that ethyl glucuronide was stored and concentrated in the gall bladder, I do not have a gall bladder, could this be the reason I passed?:confused:
