When doctors office did urine test they said it came back positive for buprenorphine! I have Not ever taken anything like this. I take oxycodoine, xanxas, actoes,diovan,metforman. The urine test was taken oct 26, Can a hair follicle test prove I did not take this? If it was present then Would it not show up in hair test? Please advise what I can do to prove my innosence? Thanks
