I have a very unusual problem. i keep testing positive for amphetamines. it has been confirmed at doctor lab as false positive and but i am losing good job opportunities because the employers do not confirm this. my medicines do not match for a false?

This is VERY: unusual and I assume each one of your "medications" have been eliminated as possible reasons for the false positive testing. OTC drugs must also be elminated. A letter from a certified S.A.P. (Substance Abuse Professional) would be my solution to your problem. This should be shown PRIOR to taking any PRE-EMPLOYMENT drug screen. Hope this is helpful Dr Z
