Ask for another test. things can get mixed up in a lab and sometimes drug combinations will give false positives for other drugs. If you're really clean so should the next test be.

I'm on a program where i have to have a weekly blood and urine test and it's occassionally come back with a false positive. When that happens, my hospital sen.ds it out to another lab for more sophisticated analysis which really breaks down the chemicals into what all could be causing the positive reading.

Good luck.
