ABSTRACT

Objective. The object of this study was to determine the sensitivity and specificity of a visual refractometer and the dextrostix in the diagnosis of neonatal hypoglycemia, using as «gold standard» the glucose-oxidase method.
Material and methods. One group of 60 newborns, with dextrostix reading of less than 40 mg/dL and risk factors of hypoglicemia, and other one of 60 healthy newborns, were subjects of study. The measurement of blood glucose was done by the three methods: glucose-oxidase, dextrostix and by the visual refractometer.
Results. The measurement with the visual refractometer had a specificity of 100% and a sensitivity of 95%.
Conclusions. The visual refractometer is an reliable method for rapid diagnosis of hypoglycemia in newborns.
