[Glucose determination in diluted whole blood using an enzyme electrode]

The construction and operation of a measuring device containing an enzyme electrode is described. Glucose oxidase is enclosed in an acrylamide film by means of photopolymerization. The maximal increase of the anodic current of the H2O2 being formed in the enzyme reaction serves as measuring signal. The device gives for diluted serum and blood correlation coefficients above 0,99 according to the methods given in the German Pharmacopeia 7. The measuring time for each specimen is roughly 90 s, the serial variation coefficient 2%.
