Test Information
This test was developed and its performance characteristics determined by Marshfield Labs. It has not been cleared or approved by the US Food and Drug Administration. This test is used for clinical purposes. It should not be regarded as investigational or for research.
This test is an LCMS/MS confirmation only for oxycodone and oxymorphone. It is intended for use only in patients where an intial drug screening test has already been performed at the time of specimen collection (i.e. Point-of-Care drug screening cup, dipstick, etc.) The specimen will not be screened by immunoassay in the laboratory; it will only be tested by LCMS/MS.
Oxycodone and oxymorphone are opiods (semisynthetic narcotic analgesics derived from the compound thebane which occurs naturally in opium). Oxycodone is available in many preparations for oral use including Percodan, Percocet, and Oxycontin. Oxycodone is partially metabolized in the body to oxymorphone. Oxymorphone is also available in an oral preparation to treat chronic pain.
Interpretations
1. Oxycodone metabolizes to oxymorphone.
2. Hydrocodone can be a pharmaceutical impurity of the Oxycodone production process. It may be present in very small amounts with high levels of Oxycodone (less than 4% of the oxycodone level).
3. Oxycodone and Hydromorphone can be pharmaceutical impurities of the Oxymorphone production process. If either are present at levels less than or equal to 0.5% of the Oxymorphone level, it is likely an impurity and not evidence of use of Oxycodone and/or Hydromorphone.
