ok this is the girl who was a tard and decided to take methadone last fri and she has a urine test this fri.... The urine goes to a lab, would they see in my system if it was in there that methadone was in there, or would they have to check it with a different test? I found this on a web site because i have been freeking out all week long about it!!!!!!!!!!!!!!!!ekkkkkkkkkkkkkkkkkkkk.... I am tested for pretty much anything, but would methadone show up or would they have to do a different test for it thanxs peace Q: Does methadone show up as an "opiate" on drug tests? A: Methadone does not cross react with the standard opiate drug screen. It must be specifically screened for.
