Zinc levels in maternal and cord blood serum during normal deliveries.
Concentration of zinc was determined by atomic absorption spectrophotometry in 90 maternal and paired cord blood sera. Forty non-pregnant age-matched women served as controls. The mean value of zinc in maternal sera was 73.4 +/- 1.5 micrograms/dl whereas the mean zinc level in cord blood of normal neonates was 114 +/- 2.4 micrograms/dl. Significantly low levels of zinc were found in pregnant women as compared to their non-pregnant counterparts, who had a mean zinc level of 113.8 +/- 3.3 micrograms/dl. The study indicates that zinc values in cord blood were significantly higher than those of the mothers, and no correlation existed between the values of zinc in maternal and cord blood sera.
