Quick answer
The Propoxyphene Urine Test is a laboratory screen that looks for propoxyphene, an opioid pain reliever that has been withdrawn from the market in many countries because of safety concerns. The test uses an immunoassay to detect the drug or its metabolite, norpropoxyphene, in a urine sample. Presumptive positive results can be confirmed with a more specific method. Results are interpreted in context by the ordering professional.
What this test measures
Propoxyphene was prescribed for pain relief and is related to methadone and other opioids. After use, it is broken down into norpropoxyphene, which can remain detectable in urine for some time. The screening immunoassay compares the sample signal to a laboratory cutoff and reports the result as positive or negative relative to that threshold.
When a screen is presumptive positive, confirmation by liquid chromatography with tandem mass spectrometry or gas chromatography with mass spectrometry can identify propoxyphene or its metabolite and report a concentration. Laboratories may also perform specimen validity testing, including creatinine, pH, and specific gravity, to assess whether the sample is suitable for analysis.
This test may be ordered in clinical or authorized testing settings and should be requested through an appropriate provider or program. Detection depends on the amount used, frequency, hydration, and individual metabolism, so timing cannot be determined precisely from a result. The ordering professional interprets the findings.
