TY - JOUR T1 - SErum calcium in the newborn AU - DENZER BS, REINER M, WEINER SB Y1 - 1939/04/01 N1 - 10.1001/archpedi.1939.01990040073004 JO - American Journal of Diseases of Children SP - 809 EP - 816 VL - 57 IS - 4 N2 - In a preliminary communication1 we outlined our objective in studying the serum calcium in the neonatal period. If there were a constant relation between the serum calcium of the cord blood and the serum calcium of the peripheral blood of infants in the first few weeks of life one might predict and prevent tetany of the newborn. If a low value for the serum calcium of the cord blood were associated regularly with a low value for the calcium in the blood of infants under 2 weeks of age, the occurrence of tetany might be anticipated. Examination of the cord blood and the peripheral blood of normal infants revealed a very different relationship and led us to inquire into the factors which govern the calcium level in neonatal life.That the cord blood has a higher level of calcium than the maternal blood is known.
