A gas chromatographic (GC) method for quantitation of flecainide acetate in human plasma is described and compared with a fluorescence polarization immunoassay (FPIA) for therapeutic drug monitoring. The GC method includes a solid-phase extraction procedure and electron capture detection (ECD) without the need of derivatization. Within-day and between-day coefficients of variation were less than 7% of GC and FPIA. Recovery was between 89-101% for the GC method. Plasma from 36 patients were analysed by both GC and FPIA and the results showed a good correlation (slope = 0.96; intercept = 0.009 micrograms ml-1; r = 0.987).

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D016231	Fluorescence Polarization Immunoassay	Fluoroimmunoassay where detection of the hapten-antibody reaction is based on measurement of the increased polarization of fluorescence-labeled hapten when it is combined with antibody. The assay is very useful for the measurement of small haptenic antigens such as drugs at low concentrations.
