My husband was given a mouth swab by CPS and it came up positive for amphetamines. Knowing there's absolutely no way the test could be correct, and being that he is on no medication that would show a false positive, he scheduled a urinalysis immediately. He also took an at-home urine test within a couple hrs after the positive mouth swab which was negative. The UA at the lab came back clear, but before closing the case CPS mouth swabbed him again. For a second time it was positive for amphetamines. So that's twice now that a mouth swab came up positive, while two UA's were negative (one lab/one home test). We're now completely dumbfounded. Shouldn't that be scientifically impossible, since the UA covers more time than the saliva? Is there any way AT ALL that a saliva test could accurately show a positive result, when a urinalysis shows negative?
