Do you know what type of test your doctor is using?

If they have really gone with the test from the lab that was the cheapest bidder for business, then it's likely that it's not a certified test and if that's the case, false positives are known to occur on the cheaper non-certified ones anywhere from 4 to 50% of the time.

The Hydromorphone is a semi-synthetic opiate and this class of narcotics is well known to cause false positives for other semi-synthetic opiates, like the Oxycodone.

The lab is in my doctors office so its probably the cheapest test that they have because he just started testing every body in the last two months and in like the only one on hydromorphone the rest r on other stuff but i looked at it and didn't see that in my test just the hydromoph contin and other meds in on and i told him that he didn't care he gave me a weeks worth and said to use those to get my self off them that he wasn't going to give me anymore. I then looked into it and everyone said the same thing that it was due to my hydromorpone more then likely cause the test didn't show that in my system. I told him that at my last apt and he said that i was probably right but he wouldn't give them back and I've never done anything wrong and i always take them when and how in suppost and always bring my bottles in with what in to have when i go to my apt so i have to live in pain he said. In on disability and have a number of problems and have test results and have had surgery to prove it but that's not good enough i also had a mri on my back two weeks after he did that and canceled it mean while my back is i so much pain at time it hurts so bad i can barely breath it hurts so bad. In in niagara falls Canada if anyone knows of a doctor who would take me on and help me please let me know i can't live in this pain for the rest of my life.

I had to take a urine test and the only thing I had taken was ibuprofen 800 and a muscle relaxer because I was on my period and regular Midol no longer works on me. I came up positive for cocaine and I hadn't used any for almost 2 years is this possible? Because I am now having to plead my case at my job and they don't believe me. Please help

I'm going to nursing school and they require a drug test for our clinical sites. I went last week to take my drug test and didn't eat anything all day, only drank 2 large cups of coffee. My results came back today as positive. It says drugs were detected but none of the drugs they have listed on the result sheet (antidepressants, antipsychotics, cannabinoids, cocaine, opiates, ect...) are circled. Only a comment is added saying caffeine was detected. Could drinking nothing but coffee all day have caused a false positive on my drug test?

I am going through the same exact thing in the military. I took my prescribed drug oxycodone an had a false positive for hydromorphone. Do you know where I can find real research on what you said about them both being semi-synthetic opioids an one can cause false test for another..
