Popis: | Background: Neonatal hypoglycemia can cause serious longterm neurodevelopmental outcome. A valid point-of-care glucometer is needed for diagnosis of neonatal hypoglycemia which is in a lower blood glucose range than diabetic patients. Aim: To estimate validity of two point-of-care glucometers for diagnosis of neonatal hypoglycemia and to determine the cut-off values for which standard laboratory confirmatory test are no longer needed. Methods: There were 180 blood specimens included. Nova StatStripTM and SureStepTM were operated at the bedside immediately after blood drawn. Laboratory tests were done within one hour. Results: On average, most of the blood glucose read-outs from Nova StatStripTM and SureStepTM were higher than laboratory plasma glucose throughout the glucose range with mean differences of 11.2±8.4 mg/dL and 13.7±6.8 mg/dL, respectively. Sensitivity, specificity, positive and negative predictive values were demonstrated. (Table 1) To obtain 100% negative predictive values, the cut-off levels were 63 mg/dL and 62 mg/dL for Nova StatStripTM and SureStepTM, respectively. Table Conclusions: None of the glucometers studied has sufficient validity to replace laboratory testing in diagnosing hypoglycemia. Confirmatory plasma glucose for diagnosis of hypoglycemia is needed when point-of-care glucometer readings are between 39 and 63 mg/dL for Nova StatStripTM and between 39 and 62 mg/dL for SureStepTM. |
