I took a hair...

I took a hair follicle test for a promotion at work and it came back positive for methamphetamine. I'm a recovering addict and even when I was using I didn't use meth. What else could cause this?

Doctor's Assistant: Is this a time sensitive issue? What type of specimen are they testing?

They used a sample from under my arm.

Doctor's Assistant: Anything else in your medical history you think the doctor should know?

I'm 50 and have COPD. I've been clean 8 years. I'm glad to answer any questions. I'm not sure what's relevant.

Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Ask Your Own Medical Question

antihistamines over the counter like brompheniramine, phenylpropanolamine can cause false positive for meth

antidepressants such as bupropion and trazodone

antipsychotics like chlorpromazine and promethazine can

and ranitidine and zantac can cause false positive

I included an article about this.

any positive test needs to be confirmed with a MS/GC confirmatory test.

let me know if you have questions.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.
