I drank 1 St. Pauly's non alcoholic beer on a Monday night no more and no less and had to take an ETG test on Friday. I've been told these new ETG tests WILL fail me because there is .05% and that they don't test the alcohol but the metabolites?? Help!! Will I fail the ETG,?

Since you drank it Monday and tested Friday, you should pass. But yes those NA beers will make you fail the test, as will many other everyday products.
