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™ C
ONTOUR™ 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 pO
2
was obtained with 116
samples. The range was 33 to 499 mm Hg, with an average of
126.9 mm 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.
