Podcast # 455: Hunting for PeeCP

Author: Michael Hunt, MD

Educational Pearls:

 

• Like all tests, urine toxicology (utox) screens can have false positives
• Prescription medications such as demerol, antipsychotics, ketamine, and tramadol can all produce a false positive utox for PCP
• Over-the-counter medication such as dextromethorphan also mimic PCP on utox
