Thank you for your question: Some additional information will help me provide you the best possible answer.

Why was the drug test done?

Was the test confirmed with GC/MS (gas chromatogrpahy-mass spectrometry) or was this a home, dipstick or other type of "instant" test?

I will be on/off through the day, so be patient - I will respond ASAP

The test was done because I belong to a Pain management group and the Doctor wants to make sure we are taking our Sec.2 drugs as prescribed.I do not know what type of test that the clinics lab used.I know at the same time it was done with my A1c,CBC ect.It was not a home or instant test I know that.Sorry for the lack of info but that is all I have for now.I do not use Pot but they said I tested Positive.

Thank you for the additional information:

There are two type of drug tests;

  • Screening tests - typically immunoassay technology, that are cheap, fast and sensitive, but not 100% specific. These test can give false positive results from other medications including common over-the-counter medications such as ibuprofen.
  • Confirmation tests - these use either GC/MS (gas chromatraphy-mass spectrometry) or LC/MS (liquid chromatography-mass spectrometry). These test take longer, are more expensive since they require large expensive equipment, however they are VERY accurate. Essentiall they give a "chemical fingerprint" of the specimen.

I suspect that the test was done without GC/MS confirmation. I would suggest asking the doctor or lab if the test was done with GC/MS, and if not, ask that the specimen be sent for confirmation to clear your name.
