[Serum proteins and specific antibodies in a German and an alien population (author's transl)].

Serum concentrations of immunoglobulins A, M and G, of alpha 2-macroglobulin, complement component C 3 and of specific antibodies against streptolysin O, staphylolysin, influenza/parainfluenzavirus and measles virus were measured from 323 German and 167 alien pregnant women. Except from a statistically significant increase of IgG and alpha 2-macroglobulin in the alien group, no measurable differences could be seen. It is concluded that the evaluation of all measured parameters can be equal for both populations.
