EMIT II Plus Propoxyphene AssayScreen for illicit use of DARVOCET

Although marketed drugs such as DARVON and DARVOCET were pulled from the market by the FDA in 2011, there is still illicit use in the U.S., a situation similar to methaqualone and QUAALUDE. The EMIT® II Plus Propoxyphene Assay detects propoxyphene and propoxyphene salts, such as propoxyphene napsylate, in human urine. It also detects norpropoxyphene (N-desmethyldextropropoxyphene), the major urinary metabolite of propoxyphene.

The EMIT II Plus Propoxyphene Assay provides:

• Excellent precision—all within-lab (total) CVs ≤1.0% or less across the assay range
• Ready-to-use liquid reagents, calibrators, and controls
• >98% agreement with the reference method (GC/MS)

Applications are available for the Viva-Jr^®, Viva-E^®, Viva-ProE^®, V-Twin^® drug testing systems; AU^® Series analyzers; Dimension^® Integrated Chemistry Systems; and Dimension Vista^® Intelligent Lab Systems.
