I use a lot of household items to clean with,also denatured alcohol, I tested positive for EtG, I use these products daily,for my cleaning buiness,I was diluted,and positive,How can that be? I am hep c positive,take a lot of vitamins cause I have no medical ins.I do drink non alcolhlic beer can that make me positive? Also my test results came back 4 days later,the judge let me off the program. 13days after the test I was told about results. I never saw my sample sealed. How do I know it was mine?
