1. In a method for measuring the glucose content in body fluids by ascertaining the output differential between a pair of adjacent oxygen sensors placed into contact with body fluids, one of said oxygen sensors being unaltered, the other of said oxygen sensors containing glucose oxidase positioned between said other sensor and body fluids placed into contact with said other sensor, whereby the sensor pair measures an oxygen content differential in body fluids placed into contact with the sensor pair, said measured differential corresponding to the extent oxygen in the body fluids has been removed by oxidation of glucose in the body fluids, being thereby a reading for the glucose content in the body fluids, the improvement which comprises measuring the level of oxygen in the body fluids and adjusting said measured differential according to the level of oxygen, whereby the adjusted measured differential constitutes a more accurate reading for the glucose content in the body fluids.
