The concentrations of trace elements in blood from healthy newborn infants.
The concentrations of 14 elements in red cells and serum in 23 healthy newborn infants were determined with the aid of neutron activation analysis. Whole blood from seven mothers was also analysed. The mothers had no signs of trace element deficiency. In newborn infants the concentration of zinc in red cells was low and that of calcium was high, as compared with adults. The copper concentration in serum was low. In the newborn infants, higher ratios of intracellular to extracellular concentrations of sodium and potassium were found, as compared with adults. Iron and rubidium values in serum and red cells were similar to those found in adults. The ratio of intracellular to extracellular concentrations for chromium was two-the same value found in adults, although the levels were lower than reported in adults.
