Measurement of phenytoin in serum using in-house reagents employing the Syva enzyme-multiplied immunoassay technique principle.
Reagents have been developed for the measurement of phenytoin in serum, using the enzyme-multiplied immunoassay approach first introduced by Syva. The assay uses a commercially available antiserum and phenytoin valeric acid coupled to glucose-6-phosphate dehydrogenase as the tracer. It has been adapted for use on an Eppendorf EPOS analyser, which allows 300 assays/h with high precision. Excellent agreement was achieved with commercial reagents, and costs were reduced markedly.
