[Immunoglobulin level (G, A and M) in healthy adults].
The simple radial immunodiffusion method was applied to determination of the quantitative content of three principal classes of immunoglobulins (G, A and M) in 987 blood sera of healthy adults, Moscow residents, aged from 19 to 50 years (donors). Monospecific antisera and standard sera were used. Investigations were carried out in men and women of three age groups: 19--29, 30--39 and 40--50 years old. The mean level of immunoglobulins G, A and M was expressed in International Units (IU/ml) and in milligrams per 100 ml of the serum (mg%). The IgG and the IgM concentration proved to be higher in women than in men in all the age groups (the detected differences were statistically significant); as to the average IgA level no statistically significant differences were revealed either by age or by sex. As a result of these studies mean levels of immunoglobulin G, A and M were determined in the blood sera of adult healthy persons, Moscow residents; which could serve as the basis for comparing the immunoglobulin content under normal conditions and in different pathological conditions of the organism.
