title: Clinical laboratory evaluation of the Perkin-Elmer KA-150 Enzyme Analyzer.
abstract: We evaluated the Perkin-Elmer KA-150 Enzyme Analyzer in a clinical laboratory situation according to a rigid evaluation protocol. The factors evaluated for five commonly assayed enzymes were as follows: (a) rate of analysis of patient samples, (b) analytical linearity, (c) overall precision (within-run and between-day), (d) carry-over from a sample with activity near 1000 U/liter, (e) error detection at low and high concentrations, (f) correlation of values with those obtained by methods used in our laboratory and (g) normal-value ranges. We find the KA-150 to be an effective and rapid enzyme analyzer.
