EXTREMELY unlikely.
yes
yes!
Phentermine can possible give a false positive on a biometric screening. Phenterime is a schedule IV controlled substance with characteristics that mimic amphetamines.
A number of things can cause a false positive drug screen. A screening test is generally inexpensive to run. Tests for specific compounds are generally more expensive. As a result, more people will get a false positive on a screening test than will get a positive on the more specific test. Still, it will cost a lot less money to run an inexpensive test and then an expensive test.
False Positive
No, folliculitis will note cause a false positive HSV2 result.
Zanaflex, or better known as Tizanidine, has not been documented to cause false positive in screening tests for drug abuse. Hence if a positive result is registered for the psychoactive drug benzodiazepines, it is likely due to other medications taken by the user that are creating the false positive.
In a screening test, maybe. The tests they do to confirm a positive result on the screening would rule this out, though, so you can probably stop worrying (unless you were hoping the answer would be yes, in which case you can worry a lot).
Yes, an error in a pregnancy test could lead to a false positive or false negative result.
Can Lamictal or depakote cause false positive screening for opiates? I am not sure about it testing positive for opiates; however, Lamictal will show a positive reading on a PCP test. Until recently it was believed to be otherwise. I will provide the documented information and studies in a follow-up post.
ppears that diclofenac and many others in the NSAID class of drugs can show a false positive. Newer urine drug screening test kits may have decreased the false positives.
Paxil is an antidepressant so the result would be a true positive, not false
