Levels of Calcium, Phosphorus, Alkaline Phosphatase, Bilirubin and Glucose in Newborn Infants and their Mothers.

Abstract

Summary: Calcium, phosphorus, alkaline phosphatase and bilirubin levels were measured in cord blood from full-term neonates and in venous blood from their respective mothers. Capillary blood glucose was measured in the neonates. The mean values in the neonates were calcium 2.56 mmol/l (10.24 mg/dl), phos phorus 1.64 mmol/l (5.13 mg/dl), alkaline phosphatase 127iu/l, and glucose 33.4 mg/dl; the median for phosphorus was 1.68 mmol/l (5.16 mg/dl). Levels of calcium and phosphorus were significantly higher in the neonates than in the mothers, but there was no difference in the mean level of alkaline phosphatase. There was signi ficant correlation between cord serum levels of calcium, phosphorus and alkaline phosphatase and the respective maternal serum levels. There was no correlation between cord serum calcium and phosphorus. The levels of blood glucose in the babies were low, with a range of 20-50 mg/dl and a mean of 334 mg/dl. 29 out of 86 babies had blood glucose less than 30 mg/dl, but none of these babies was sympto matic
