The automated method of O’Neal and Gochman [Clin. Chem. 16, 985 (1970)] for determination of serum and urine amylase activity has been modified to increase its accuracy, precision, and efficiency. Sampling rate is 50 specimens per hour. The analysis depends on agr-amylase hydrolyzing glycogen to maltose-like subunits, which are measured with the copper neocuproine reaction. Results obtained by this method are compared to those for a manual reference method [Clin. Chem. 6, 434 (1960)].
