Copper levels at term.
J Coll Physicians Surg Pak Jan ;9(1):35-7.

Copper (Cu) was analyzed in the maternal and cord blood in 52 women at delivery and 22 age matched nonpregnant controls and its correlation was studied with Zinc, Magnesium, Calcium and Phosphorus. Copper levels were found significantly elevated in maternal blood and lowered in cord blood. Maternal age, parity, miscarriage before this pregnancy or sex of new born had no significant influence on the distribution of Copper levels in blood. A negative correlation was observed between birth weight and Copper levels and were found significantly higher in the cord blood of babies below 3 kg in weight. Correlation studies with other trace elements revealed a positive correlation between Copper and Zinc only both in maternal and cord blood.
