Normally, the relative amount of B-lymphocytes carrying IgG in adults is 2-6%, the absolute amount is 0.04-0.11 × 10 9 / l.
B-lymphocytes carrying IgG, - cells of humoral immunity, responsible for the synthesis of antibodies. They are formed in the red bone marrow and accumulate mainly in the peripheral lymphoid organs. Peripheral blood contains only 2-6% of their total number. The ratio of populations in a common B-lymphocyte pool is important in assessing humoral immunity. The violation of the ratio is characteristic for insufficiency of humoral immunity.
