I received a copy of my EtG test that read as a positive abnormal with a cutoff of 500 ng/mL. after reading up on the test, I'm still not sure what that means exactly. I'm being summoned to court for violating my probation and I'd like to know what this test means before I go in.

First were you still drinking,
If you do not drink any more, it may mean it showed a dulited test, or showed other material in test, some people try silly pills or vitamins to hide the test.which caused a bad test.

So tell us the facts leading to the test.

The test was given to me the day after christmas. I have been abstaining from alcohol and indulged with my mother on christmas at dinner. I knew I wasn't going to pass this test but I'm curious as to what the abnormal positive means. I don't want to go in there and say I had one glass of wine if the results of this test show that I had more than that. The test says it could have been rated H for high L for low or A for abnormal. Mine is abnormal even though I didn't do anything to it. I also would like to know the difference between the level cut offs... I don't quite understand them.
