[Normal values of IgA, IgG, IgM, a1-antitrypsin, C2-complement, C4-complement, ceruloplasmin, haptoglobin and transferrin in serum of healthy, matured newborns and comparison with adults. Method: kinetic nephelometry. (author's transl)].

Concentrations of IgA, IgG, IgM, a1-antitrypsin, C3-complement, C4-complement, ceruloplasmin, haptoglobin and transferrin were determined by the kinetic nephelometric method in fasting blood serum of 88 healthy, matured newborns (male=46, female=42) and of 50 healthy adults (male=12, female=38). The age specific comparison showed that all the nine examined proteins had significantly lower levels in the group of newborns. Sex specific differences were not detected in the group of newborns.
