A member asked:
I took an antihistamine and failed a drug test for klonopin (clonazepam) is this possible?

If it was a rapid: read test there can be multiple false positives based on the manufacturer and the test its self. If it was sent for a confirmation using gas or liquid chromatography and mass spectrometry it will show what is really in the urine. any rapid read test should be followed up with a confirmation if there is anything unusual so if it was not done ask for it to be run.
