I did my Certiphi drug test last week and it came back negative across the board. However, I take prescription Adderall everyday so it definitely should have come back positive for amphetamines. I talked to Certiphi support and they said I could add a statement to my test result which would then get sent to the dean. Not sure what the best course of action is here because I'd rather not disclose ADHD to my admin if it can be helped, but I also don't want the report to get corrected two or three years down the line and cause problems for me. I'm planning to add the statement saying it should have returned positive for amphetamines, but hoping to get an opinion from @LizzyM, @Goro, @gyngyn or another adcom guru before I do anything.
