Oxycodone with Metabolite Confirmation, Chain of Custody, Random, Urine
Use
This test is useful for the detection and quantification of oxycodone, oxymorphone, noroxycodone, and noroxymorphone in urine. It is particularly relevant in legal settings where chain of custody documentation is required to ensure that the specimen remains untampered. The test helps in determining recent exposure to oxycodone, generally within the last 2 to 3 days, which is crucial for legal and medical decision making.
Special Instructions
The test requires a chain of custody kit to ensure appropriate handling and documentation. This is essential for legal defensibility, protecting the individual by documenting all personnel who handled the specimen. It is important to submit specimens using the provided documentation to comply with chain of custody requirements.
Limitations
The test is specific to oxycodone and its metabolites; it does not detect other opioid drugs such as fentanyl, meperidine, methadone, or opioid antagonists like naloxone. The detection period for oxycodone exposure is within 2 to 3 days prior to specimen collection and may not capture use beyond this time frame. Additionally, improper handling or processing can compromise results.
