A scary truth that we have to face in the world of Drug Testing is that false positives are real, and despite what the labs will have you believe they happen more often then we’d like them to. A Study concluded not too long ago that took over 150 over the counter medications and despite them all being easily accessible and used by many on a regular basis, at least 65 of them returned a false positive result in some of the most standard and widely used form of urine drug test. To date there are hundreds of over the counter drugs and medications that can cause false positives and many of them you wouldn’t even realize or think twice about taking. Aleve, Tylenol, Advil, and many other head ache medications often cause false positives for THC.

As an amusing side note, your own body can give a false positive without the help of any medications because diseases that affect your kidney and liver can cause your body to produce similar metabolites that the drug use could leave behind. Make sure the lab knows you have Diabetes, or another form of Kidney or Liver Disease. The truth is though that most labs and employers won’t care that you’re challenging the results by insisting that the results must be a false positive, no matter how much research and proof you show them. Labs aren’t always up to code, and your potential employer can choose to use any lab they see fit to, there are currently no requirements of the labs and employers who use them to set a specific standard, so insist that they ask you what you’ve taken recently, and insist that they do test your sample at least twice before determining the results.
