Accuracy of Serum Anticonvulsant Measurements

Abstract
An enzyme multiplied immunoassay technique is compared with a gas-liquid chromatographic technique for the measurement in blood serum of the anticonvulsants phenytoin, carbamazepine, phenobarbitone, primidone, and ethosuximide. The correlation between results obtained by each method was excellent, and both systematic and random errors were well within acceptable limits.
