I had the same thing happen to me a few months ago, except my urine tested negative for both of the opiates that I'm prescribed (methadone and oxycodone
). My doctor stated that the urine
cup that I used must have been defective, and that was the end of it, lucky for me (I did offer to give another sample, which the doctor declined to accept, maybe due to the cost of the "instant result" test cup?).
