About Oxycodone/Oxymorphone and Metabolite Screen, Urine in St. Charles
This assay targets a specific pair of semi-synthetic opioids and the compounds they break down into after ingestion.
Oxycodone is a semi-synthetic opioid agonist prescribed for moderate to severe pain. After it is taken, the liver converts a portion of it into oxymorphone, a more potent metabolite, and into other inactive or less active byproducts. The screen is designed to flag both the parent drug and these metabolic derivatives so that exposure can be identified even after the parent compound has been largely cleared.
Urine is the specimen of choice for this screen because the kidneys concentrate drug residues and metabolites over a window of hours to a few days, depending on dose, metabolism, and hydration. The test typically employs an immunoassay as an initial qualitative screen, and any presumptive positive result may be confirmed by a more specific method such as gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry.
Results are reported qualitatively as negative or presumptive positive, with confirmation available when required. A positive finding indicates that oxycodone, oxymorphone, or their metabolites were present at or above the assay's cutoff concentration; it does not by itself establish impairment, dose, or the time of last use. Interpretation should always account for the individual's prescribed medications, medical history, and the possibility of cross-reactivity from related compounds.
