The Propoxyphene (PPX) Rapid Test Device is intended for the qualitative detection of Propoxyphene in human saliva at cut-off concentrations of 25/50 ng/ml. It serves as an initial screening tool for use in settings where monitoring for propoxyphene abuse or compliance is critical, such as workplace drug testing, clinical toxicology screenings, substance abuse rehabilitation programs, and law enforcement operations. Propoxyphene, though weaker than morphine or codeine, can cause side effects including shallow breathing, slow heartbeat, confusion, hallucinations, and seizures, particularly with accumulation of its metabolite. This assay provides only a preliminary analytical result. A more specific confirmatory method, such as gas chromatography/mass spectrometry (GC/MS), must be used for definitive confirmation, especially in legal or disciplinary contexts. Professional judgment should be applied to any drug test result.
