[Determination of low blood glucose levels in newborns with the reflectance photometer (author's transl)].

The paper reports the examination of a new test strip Reflotest-Hypoglycemie, which was developed specifically for the hypoglycemic range. In 2 series of 110 respectively 120 samples of capillary blood taken from premature and full term infants the blood glucose concentrations were determined using Reflotest-Hypoglycemie and the hexokineasured with the test strip agree well with the results of hexokinase method in a range less than 50 mg/dl. Bilirubin and hematocrit values do not affect the glucose test. Glutathion and ascorbic acid interfere with the test strip method but this error is neglectable because of physiological low concentrations of these substances.
