Fluvoxamine (Luvox)
Use
Fluvoxamine measurement is key in evaluating therapeutic levels for managing patients undergoing treatment with this medication. It helps optimize drug dosing and monitor patient compliance. Fluvoxamine is an antidepressant elevating neurotransmitter action and used in treating obsessive-compulsive disorder as well as major depressive disorder. Monitoring serum or plasma levels ensures effectiveness while avoiding toxicity.
Special Instructions
Important to use the correct tube type: green-top sodium heparin for plasma or plain red-top for serum. Specimen transport is critical — refrigerate samples and avoid using gel tubes to maintain specimen integrity. Timely sample receipt guarantees accurate analysis and reporting.
Limitations
Specimen integrity can be compromised if gel tubes are used, as they are not acceptable for plasma or serum collection. Also, mild hemolysis, lipemia, or icterus do not seem to impact the analysis, but any extraneous interference should be avoided for precision. Changes in matrix composition can cause assay variability, influencing fluvoxamine quantification. Therefore, submitted specimen volume is essential to ensure comprehensive analyses in repeat or confirmatory testing.
