Oxycodone drug testing detects the presence of oxycodone, a prescription opioid pain medication, in the blood. It is ordered to monitor prescribed use, evaluate possible misuse, or investigate suspected overdose. Blood testing measures current levels rather than past use.

What it measures

  • Oxycodone — The parent drug; shows recent use.
  • Noroxycodone — A breakdown product; helps confirm oxycodone exposure.
  • Oxymorphone — Another metabolite; may indicate how the body processes the drug.
  • Other opioids — Sometimes checked to rule out other substances.

Who it is for

Healthcare providers order this test when monitoring pain treatment, assessing possible misuse, or evaluating emergency symptoms like extreme drowsiness or slowed breathing.

Preparation

No fasting or special preparation is needed. Tell your provider about all medications and supplements you take, as some can affect results.

Results and what they mean

Results are reported as a concentration of oxycodone and related substances in the blood. A clinician interprets these levels alongside your medical history and symptoms. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
