Abstract
.alpha.-Amylase was measured in 57 patients'' sera with normal to highly elevated amylase activities. The results obtained with 4 enzymatic-kinetic test-kits have been compared with those from 5 conventional marketed procedures. The results are evaluated by regression analysis. The specificity of the methods was analysed with amylase samples from human pancreas, human saliva and pig pancreas. The susceptibility of the kinetic procedures to interferences is smaller. The problems of conversion of activity units and reference ranges are discussed. The UltraZyme and the Monamyl neu-methods were found superior to the other procedures because of their good practicality, precision and broad linear range; thie specificity for diagnostic purposes in pancreatic diseases is less favorable than that of conventional procedures.
