What does elavil show up on a drug test?

I have taken Elavil for a year now and have been both urine and blood tested for drug screens and it has never created a false positive for any drug so far. Just inform the testing site you are on it and there is usually a way they can decifer which drug it is in your system. Hope this helps, good luck as long as this is your only worry you are doing good my friend. Take care, marjorie zych

False positives for opiates for up to three days, LSD, Methadone.

Take care.
