Summary A study is made of calcium contents in arterial and venous cord blood, the plasma calcium of the newborn (aged 1 to 3 days) and of the mother in 15 cases. The blood entering the infant from the afterbirth invariably contains more (0.3–2.3 mg/100 ml) calcium than the blood brought back from the infant. The calcium contents of the blood entering the placenta and of the infant's blood after birth are approximately on the same level, and the values are frequently higher than for the calcium of the mother. The findings of earlier investigators that the elevation of the cord calcium is high as compared to calcium of the infant, is mainly due to the circumstance that no separate consideration has been given to umbilical artery and umbilical vein.
