Oxymorphone Confirmation, Random, Urine
Use
The Oxymorphone Confirmation, Random, Urine test is used for the detection and quantification of oxymorphone and noroxymorphone in urine. It helps confirm exposure to oxymorphone and oxycodone, as oxymorphone is a metabolite of oxycodone. This test is crucial for monitoring compliance and detecting potential misuse in patients prescribed these opiates. The detection interval for opiates is typically 2 to 3 days after last ingestion.
Special Instructions
For situations requiring chain of custody, a Chain of Custody kit is available, and OXYCX / Oxycodone with Metabolite Confirmation, Chain of Custody, Random, Urine should be ordered. Additional drug panels and specific requests can also be arranged by contacting the laboratory directly. Test requests not submitted electronically should include a Therapeutics Test Request form.
Limitations
This test does not detect other opioid class drugs such as fentanyl, meperidine, methadone, or opiate antagonists like naloxone. Improper specimen collection, handling, or test selection might affect results. The test is limited to the detection and quantification of oxymorphone and noroxymorphone, which is a metabolite of oxycodone, potentially leading to false interpretations regarding opiate use if not clinically correlated.
