Is methadone tested for on a standard mouth swab drug test?

wow....i looked for the answer to this question for a couple days....YES,they do! People were saying "not unless they do a specific test for methadon".... They do where i live (Indiana) 1 pill and that is the only time ive ever taken anything i didnt have a script for. took a half in the morning and a half in the evening. failed a swab test 4 days later....
