Use of an Enzyme Standard in the Measurement of Enzymes in a Clinicon Reaction Rate Analyser

Abstract
Measurement of enzyme activity in a Clinicon reaction rate analyser was carried out in two ways: one method was based on absolute calibration and the other used an enzyme standard which involved adjustment of results according to the value for the standard obtained in each batch. Batch calibration significantly improved long-term precision and reduced differences between results obtained in different instruments.
