[Serum immunoglobulin content in blood donors]
The content of IgG, IgM and IgA was studied in the blood serum of 408 donors aged from 18 to 46 years and older (217 men and 191 women). The results obtained were expressed in the IU and in absolute values by protein. It was established that the quantity of immunoglobulins of all the three classes increased with the advance of age. There was no strict correlation between the immunoglobulin level depending on sex, although for some individual age groups there was noted a statistically sinificant difference in the IgA and IgG content.
