Abstract

An economical, very sensitive and precise automated method for the determination of plasma glucose by glucose oxidase is presented. At 60 determinations per hour the method required 0·05 ml. of plasma and can conveniently determine glucose levels in the range of 0 to 500 mg/100 ml. Recovery experiments gave mean yields of 99% and, for 100 specimens analysed in duplicate, the precision was 1·24 mg/100 ml.
