tested 15ng/ml on SAP 5-50 I thought cut off is 50ng/ml,what can I do?

What can I do? I took an SAP 5-50 UA test recently. I tested at quest labs and the initual results came back all negative. My employer decide to verify the results and I was told that the THC came up at 15 ng/ml. Can they do this legally if the cutoff for screening is 50 ng/ml and all the test results were negative? The paperwork says negative on all 5 drugs tested with 15 ng/ml next to the THC under confirm. It doesn't even say positive anywhere on the test. I have lost my job because of this. Is this legal? My employer won't let me retest, can't I retest by law? I have nothing against the use of marijuana, it is safer than the other drugs, but I don't even use marijuana and came up with this test result. I would apreciate any advice..especially legal advice on what I can do. Any links on legal information would be apreciated.

Sounds like you need to talk to a lawyer that specializes in this .... Your employer can probably fire you for whatever reason he wants, unless you are protected by a union, or a discrimination law. But I'm no laywer and the laws probably vary by country/state.

If you don't smoke MJ, maybe you can get small amounts of THC from other sources, or being around smokers. Or the lab could have messed up the test.

you might want to post this in the Legal section....
