Considerable variation was observed in immunoglobulins, estimated in 75 preschool children. The mean +/- 1 SD levels of IgG, IgM and IgA were found to be 1241 mgs% +/- 366, 149 mgs% +/- 48,231 mgs% +/- 99 respectively. A significant correlation of serum albumin was found with transferin and hemoglobin, but none existed between hemoglobin and transferin.
