In 60,2% (308 out of 512) of children aged 1-16 years of Mogilev region with repeated respiratory infections, the content of total serum immunoglobulins IgG, IgА, IgМ is within the age limits. Correlations between the total serum immunoglobulins of children whose immunoglobulin values are outside the reference intervals and children whose immunoglobulin values are within the reference intervals have statistically significant differences. 39,8% of children aged 1-16 years have dysimmunoglobulinemia, and its frequency increases with the age of children: up to ten years within the average values for the entire group of children (1-2 years -26,4%, 3-5 years -27,6%, 6-9 years – 31,5%), 10-13 years – 50,5%, 14-16 years – 75,8%. In children with immunoglobulin values that go beyond the values of reference intervals (RI), the following 13 variants of combining the levels of total serum immunoglobulins are most common: IgGRI-IgA↓, IgGRI-IgM↑, IgGRI-IgM↓, IgАRI-IgG↑, IgАRI-IgG↓, IgАRI-IgM↑, IgАRI-IgM↓, IgМRI-IgG↑, IgМRI-IgG↓, IgМRI-IgA↓, IgA↓-IgG↓, IgA↑-IgG↑, IgM↓-IgG↓, IgM↓-IgA↓.
