Determining compliance or identifying illicit opioid drug use using urine specimens

 

This test is not intended for employment-related testing.

Highlights

This test uses high-resolution accurate mass spectrometry to identify 33 different opioids and/or metabolites where immunoassays are not adequate.

 

This test offers lower detection limits than previous Mayo Clinic Laboratories-offered screens.

 

This test has the ability to detect "spiked" samples.

Urine

Additional Testing Requirements

In most cases, no additional testing is needed after the qualitative targeted opioid test is performed if the parent/metabolites found are consistent with the patients prescribed medications. However, if unexpected opioid parent/metabolites are found, confirmatory testing can be requested at an additional charge.

Determining compliance or identifying illicit opioid drug use using urine specimens

 

This test is not intended for employment-related testing.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Opioids are a large class of medications commonly used to relieve acute and chronic pain or help manage opioid abuse and dependence. Medications that fall into this class include: buprenorphine, codeine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, oxymorphone, tapentadol, tramadol, and others. Opioids work by binding to the opioid receptors that are found in the brain, spinal cord, gastrointestinal tract, and other organs.

 

Common side effects include drowsiness, confusion, nausea, constipation, and, in severe cases, respiratory depression depending on the dose. These medications can also produce physical and psychological dependence and have a high risk for abuse and diversion, which is one of the main reasons many professional practice guidelines recommend compliance testing in patients prescribed these medications.

 

Opioids are readily absorbed from the gastrointestinal tract, nasal mucosa, lungs, and after subcutaneous or intermuscular injection. Opioids are primarily excreted from the kidney in both free and conjugated forms. This assay doesn't hydrolyze the urine sample and looks for both parent drugs and metabolites (including glucuronide forms). The detection window for most opioids in urine is approximately 1 to 3 days with longer detection times for some compounds (ie, methadone).

Reference Values

Interpretation
Provides information to assist in interpretation of the test results

If an opioid or its corresponding metabolites is identified (present), it indicates that the patient has used the respective opioid in the recent past. The absence of expected opioids or their metabolites may indicate noncompliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, diluted or adulterated urine, or limitations of testing. The concentration of the drug must be greater than or equal to the cutoff to be reported as present. If a specific drug concentration is required, the laboratory must be contacted within 2 weeks of specimen collection/testing to request quantification by a second analytical technique at an additional charge.
