Special Instructions
Not provided.
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.
