Quick Fix 5.7 Issue with False Positives

Today I had a 10 Panel Drug test for pre-employment. Everything went well with the QF 5.7 temperature wise, but when the staffer for the temp agency read the results, I was floored! It came back positive for MTD (methadone), BZO (benzodiazipenes) and BAR (barbituates)!!!! I would have been better off using my own urine, lol! Has anyone experienced this or heard about a defective batch of QF? Could it be that the 10 panel test is more sophisticated?

Thanks,

Three possiblilities:

- A shady scam vendor had sold you a bogus batch (replaced with "dirty" urine and passed off as synthetic)

- An untrained tech saw faint lines on the 10 panel Immunoassay and misinterpreted them as "positives".

- This story is fabricated out of whole cloth.
