[Clinical assessment of a new glucose reflectance meter (Glucoscot II) for the detection of neonatal hypoglycemias].

Glucoscot II, a new glucose reflectance meter and the corresponding test strip "Glucopat" were evaluated for their accuracy in the detection of neonatal hypoglycemia. In 100 neonatal blood samples of 44 neonates glucose was estimated with the reflectance meter and the results were compared with those from a reference method (Beckman-Glucose-Analyser). Hypoglycemia was defined as blood glucose of less than 2.2 mmol/l (40 mg/dl). The correlation between the values obtained by the test strip and the reference values was high (= 0.95). Test sensitivity was 100%, specificity 99% and the predictive value for hypoglycemia was 94%. The incidence of a blood sugar less than 2.2 mmol/l in our study population was 15%. Thirteen percent of glucose values determined with the reflectance meter deviated from the reference value by more then 20%. If our data can be confirmed by others we conclude that the Glucoscot II/Glucopat-system can be recommended as screening-test for hypoglycemia in neonates.
