Answer
Dear Chris

Thanks for our rating and apologies for my curt reply and glad you understand where I am coming from. Ubnfortunately the system does not keep rejected questions so could you re-ask and I'll answer asap.

False positives are common especially by some laboratories who are careless and only after the money. I cannot see that you would test dirty with a urine test unless you had intercourse almost immediately before the test, even then I would doubt it would matter. Tests can be very sensitive but they should always follow up with a blood test or even a tissue (eg hair test)if suspicions are aroused. As I see it your fiance could only make you positive if she were doping you which sounds very improbable and you would know it. All you can do is argue your case, demand a further test and keep a sealed sample for retesting at another laboratory in case the same happens again.
