What is the cause of false positive Acetaminophen serum level test?

3 May 2010

I don't know what type of acetaminophen serum level test your hospital uses, but I do know that there have been reports of patients with elevated levels of a substance found in the liver, called bilirubin, having false positive acetaminophen levels.

I would be careful though, maybe acetaminophen was accidentally given to this patient. It would be helpful to check her medication list to make sure she isn't getting any combination ingredient medications that might have acetaminophen in it, and make sure that visitors didn't accidentally give her a pain medication not realizing that there was acetaminophen in it. You always want to be safe, and not just assume it is a false positive.

I hope she is doing well!
