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.
would lisinopril come up as a false positive for methamphetimines
no
Don't know about the epolamine. Can't find in my drug book. Diclofenac though, is part of diclofenac potassium, and diclofenac sodium, which are non-steroidal anti-inflammatories(NSAIDS). I can't locate any literature that says there is anything in them that would show up on a drug test. Most drug tests are highly specific. They look for THC, opiates, amphetamines, cocaine, and barbituates. Normal NSAIDS have NONE of those as ingredients.
A hair test will show positive, if you have been using.
No
Can vicodin cause false poative for weed
no
no
None.
I have no idea. It should show up as a true positive for opioids.
Yes! Lamictal will show a false positive on drug screens. You can have a lab use a maspectrometer specifically for PCP in order to officially rule it as a "false positive."
In VERY high doses it can rarely show a false positive, but that kind of dosage would be very unsafe.
