A complex of laboratory studies aimed at assessing the state of humoral immunity of the human body. The study allows us to determine the degree of damage to the immune system, choose the tactics of further immunomodulatory therapy, as well as assess the degree of its effectiveness. 

The main pathologies associated with a deficiency or excess of IgA, IgM and IgG. The lack of antibodies is often associated with immunodeficiency, which can be congenital or acquired. Deficiency of IgA, IgM and IgG can be accompanied by the appearance or exacerbation of diseases: infectious (respiratory tract infections, ENT organs, etc.); autoimmune (rheumatoid arthritis, systemic lupus erythematosus, etc.); allergic (rhinitis, asthma, etc.). The causes of excess antibodies are most often: acute or recurrent inflammatory diseases of various of nature; pathologies in which cells responsible for the production of immunoglobulins degenerate into tumors (monoclonal and polyclonal gammapathies). 

Indications: frequent colds; suspected immunodeficiency associated with IgA, IgM or IgG; impaired humoral immunity; recurrent herpes; frequent or long-lasting infectious diseases; severe or recurrent course of infectious and autoimmune diseases; comprehensive diagnosis of tumors, including hematopoietic and lymphoid tissues.

·Children under the age of 1 year should not eat for 30-40 minutes before the study, from 1 to 5 years - for 2-3 hours, and from 5 years - for adults - for 12 hours.

·You can drink clean, non-carbonated water.
