Evaluation of EMIT methods for the determination of the five major antiepileptic drugs on an automated kinetic analyser.
We have evaluated the performance of enzyme-multipled immunoassay methods for the five major antiepileptic drugs on an automated system, the Perkin-Elmer Model KA-150 Kinetic Analyzer. The precision in the normal duplicate mode was found to be in the range of 6% to 10% for all five tests over a typical working day. All EMIT methods were compared to gas-liquid chromatographic procedures and, in addition, the phenytoin and phenobarbital assays were compared to a liquid-chromatographic method. The phenytoin assay was also compared to RIA and to a manual spectroscopic method. In general, most of the comparison studies resulted in acceptable correlation, although one gas chromatographic method did not correlate very well with the phenytoin and phenobarbital immunoassays.
