Clinical Significance
If the propoxyphene screen is ≥ 300 ng/mL, the major metabolite, norpropoxyphene, will be confirmed by GC-MS at an additional charge.
Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen.
This test is intended for clinical monitoring and management of patients. It is not intended for non-medical use such as employment or forensic testing.
Intended Positives:
Propoxyphene
Darvocet-N
Darvon, Novrad
