What Causes False Positive Urine Test Reports For Fentanyl And Codeine?
I have had 2 urine screenings in the past month and a half. The first one came back with a trace of Fetanyl in it and the second (2 weeks later) showed a positive for codine. I didn t even know what Fetanyl was and I have not taken anything with codine in it. The only thing I can think of that is different is I had a flu shot. Can you please help me why this has happened?
