Do you eat any food containing poppy seeds like muffins or bagels - I believe that they can produce a false positive. I forget what the metabolite they test for but the USDA states: However, it is known that morphine and codeine can sometimes be detected in the urine up to 48 hours after ingestion of poppy seed from some pastries such as bagels, muffins, and cakes.

Hi Bwoods,

Welcome to our Pain Management Community. I'm sorry to hear about your false positive drug screens.

I wish I had a good answer for you, I don't. Drug screening is simply chemical interaction - which is not my strong suit.

As Phil said, and is common knowledge in our community, those instant UDS (Urine Drug Screens) are very often not reliable. We assume the lab your PMP is utilizing does the much more accurate immunoassay screening.

Has your PMP said you will be dismissed? Can he/she provide a reason for the "failure"?  I had a PMP that changed labs because of so many failures in his drug screens. He said, "I know my patients - they were compliant." Once he changed labs the UDSs returned as the PMP suspected they would. Human error does happen - though rare.  

Talk to your PMP. It makes no sense to me that someone on Suboxone would consume opiates when they will have no effect. Plus I happen to believe you and most ppl that come here and post their innocence. If you have a good relationship with your PMP it may make a difference.

Please let us know how this turns out. We're here to support you - and offer what we can. My heart goes out to you.

Good Luck an Take Care,
~Tuck

While buprenorphine metabolites do not include these opioids, false positives can include morphine, codeine, heroin, and opium. The instant UDT test is simply not accurate.

Incidentally, the naloxone in your Suboxone film will nulify any effects of opiates like morphine.

A specific quantitative testing for buprenorphine should be made to monitor compliance with Suboxone therapy.

In any case of UDT immunoassay false positives, doctors should talk with their patients to assess any noncompliance or risk for abuse using clinical judgment.
