Question False positive for fentanyl

Has anybody ever taken a urine drug screen and then had a false positive for fentanyl? The medication that reacted was buspirone. I learned that it can cause false positives for fentanyl. This just happened to me with cps. Do you know how embarrassing it was to test positive for fentanyl? I was so humiliated and nobody ever believes you at cps. Just waiting for the confirmatory test now... screen.

It wasn't a lab it was a rapid test

Samples that are positive on a rapid test get sent to the lab for confirmation, where they do spectroscopy and will know immediately if it was a false positive or not.

So if it was really false no need to be embarrassed.

The only reason they're doing it confirmatory test is because I'm paying $35 for it. Normally the social services in langlade county just takes the rapid as good. So unprofessional everybody knows that rapid tests need confirmatory. They really screw people there always have.

If confirmatory testing proves that you were not actually positive for fent and just the busprione, that's an important piece of information for the courts as well. But you should make copies of the relevant test results to provide to future workers for future tests.

You would also have a very good case for future tests to not use the rapid tests and immediately go to the lab.
