Determination of Glucose in Biologic Fluids with an Automated Enzymatic Procedure

Abstract
An automated procedure for the enzymatic determination of "true" glucose with the glucose oxidase-peroxidase system is described. A threefold increase in sensitivity was obtained through measurement of the stable, pink chromogen obtained at high acid concentration. Good reproducibility and stoichiometry was obtained over the range of 50-400 mg./l00 ml. at a sampling rate of 40/hr. The normal range (70-105 mg./100 ml.) and the error of the method (±2.0%) are about the same as that obtained with the manual method of Saifer and Gerstenfeld (7).
