Neonatal Blood Evaluation (Performance with Neonatal / Hospitalized Infant Samples)
Neonatal samples (n = 306) were collected from routine, intermediate care, and intensive care nurseries at three sites. The infants ranged in age from less than one day to 5 months (11 wks. premature birth). The median age was two days. Nine venous, 176 capillary and 121 arterial samples were evaluated with the Ascensia™ CONTOUR™ Blood Glucose Monitoring System using three reagent lots. The lots were rotated each day of sample collection over the duration of the evaluation. Meter results were compared to laboratory glucose assay methods used at each of the sites (Corning 860, Beckman LX20, Hitachi 917 analyzers). Sample glucose concentrations ranged from 0.8 to 11.5 mmol/L, with an average of 4.6 mmol/L. The hematocrit range was 21 to 70%, with an average of 48.3%. A pO2 was obtained with 116 samples. The range was 33 to 499 mm Hg, with an average of
126.9mm Hg. A bilirubin assay was performed with 283 samples. The range was 3.4 to 319.8 µmol/L, with an average of 95.8 µmol/L.
