Tramadol and Metabolite, Quantitative, Serum or Plasma
Also known as: TRAMADOL
Use
This test is used for therapeutic drug monitoring of Tramadol and its metabolite to ensure patient adherence to medication. Monitoring serum levels is crucial because the concentration of the drug in the blood decreases rapidly after administration, necessitating peak level measurement for accurate assessment.
Special Instructions
Not provided.
Limitations
The test uses High Performance Liquid Chromatography-Tandem Mass Spectrometry, which while precise, requires careful handling of specimens. Separator tubes are unacceptable, and care must be taken to separate from cells within two hours to ensure accurate results. As the test is not FDA approved, performance characteristics were established by NMS Labs.
