Propoxyphene Urine Test in Nevada

A propoxyphene urine test checks for the presence of propoxyphene, a prescription pain reliever, or its breakdown products in urine. It is ordered to screen for recent use, monitor adherence to a prescribed regimen, or investigate possible misuse.

What it measures

Propoxyphene — The parent drug; its presence suggests recent use.
Norpropoxyphene — A metabolite that stays in urine longer than the parent drug.
Screen result — A preliminary positive or negative based on a cutoff level.
Confirmation result — A more specific follow-up test, if needed, to verify a screen.

Who it is for

Healthcare providers, employers, or substance-use programs may order this test. It is not part of routine health screening.

Preparation

No fasting or special preparation is usually required. Inform the lab of any medications you take, as some may affect the result.

Results and what they mean

Results are reported as negative or positive, sometimes with a numerical level. A positive screen is typically confirmed by a second method. Only a qualified clinician can interpret these results in your context; this is general information, not medical advice.
