Customer Question
I do not do...

I do not do any illegal drugs, however I ended up in the emergency room the other day. I had passed out and hit my head. They took blood. I was severely dehydrated. However, I have no idea how the blood test showed positive for methamphetime.

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

Not time sensitive, but I'm a driver and don't do illegal drugs. Just wondering how this positive blood test could have happened

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

No, nothing but the occasional cold, headache, and flu

Doctor: Dr. David, Board Certified Physician replied 4 months ago

some cold and flu medications can cause false positive for meth

antihistamines and decongestants like

Brompheniramine and Phenylpropanolamine and nasal sprays can cause false positive for meth.

Antidepressants like bupropino and trazodone can as well

antipsychotic mediations can cause positive

stomach acid reducing medicaitons like Zantac and ranitidine can cause false positive.

I included a medical article which talks about this

any screening tests which show positive will have to be confirmed with a MS/GC confirmatory test

if you didn't use meth, your confirmatory test should be negative

let me know if you have questions.

I feel better already! Thank you.

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.
