Serum immunoglobulin (Ig) G, A and M levels were measured and compared in healthy white and black pre-school children. A significant difference between the two races was found. Black children generally had higher serum immunoglobulin levels than white children. Apart from the groups as a whole, there were also significant differences between the serum IgG values of the black boys and girls separately in comparison with the levels of white boys and girls.
There was also a significant racial difference in respect of the serum IgA values of the girls and in respect of the serum IgM levels of the boys of the 2 groups. Scrum IgM levels of the white girls were generally higher and differed significantly from those of the white boys.
