Evaluation of an automated immunochemistry analyzer, the Auto ICS

The Beckman Instruments' Automated Immunochemistry System, the Auto ICS is a fully automated version of the ICS. This evaluation examines several analytical and cost parameters for five representative assays: IgG, IgA, IgM, phenytoin, and phenobarbital. Correlation with more established methods was excellent, with the coefficients of correlation being 0.9880, 0.9948, 0.9862, 0.9812, and 0.9618 respectively. Intra- and interassay precision was on a par with other immunoassays, with CVs varying from 1.8% to 9.5%. Linearity of each assay was verified. The instrument can be cost-effective, if the simultaneous assay feature is used on batches of at least six samples. The instrument requires very little operator maintenance.
