Casandra Test Code LC19053Version 1 (DRAFT)
Performing Lab
Dextromethorphan (DM) and Metabolite, Quantitative, Urine
Also known as: Methorphan
Clinical Use
Order TestUse
Detect presence of dextromethorphan, an over-the-counter cough suppressant with abuse potential
Special Instructions
Not provided.
Limitations
This test cannot distinguish between dextrorphan (a dextromethorphan metabolite) and levorphanol in the analysis process. Therefore, a positive result for dextrorphan does not rule out the presence of levorphanol due to potential indistinguishable analysis characteristics.
