IgG – total

Immunology, as a science, is constantly evolving, providing new opportunities in the diagnosis and treatment of various diseases. One of the key components of immunological research is the study of antibodies, in particular immunoglobulin G (IgG). IgG is the most common class of antibodies in humans and plays an important role in immunity, as well as in the diagnosis of allergic reactions and other immunological diseases.

IgG are antibodies produced by the body in response to secondary immunogenic antigens, such as bacteria, viruses, allergens, and other foreign substances. They perform a number of functions, including neutralizing and phagocytosis of immunogens, as well as activating the immune system to destroy infectious agents. IgG can also be the cause of allergic reactions and autoimmune diseases when it interacts with the body's own cells.

To diagnose various diseases and determine the patient's immunological status, it is important to know the level of IgG in the blood. A study of the total level of IgG helps to identify immune problems, such as immunodeficiencies, and also to assess the degree of activity of allergic reactions.

One of the main methods used to measure total IgG levels is the enzyme-linked immunosorbent assay (ELISA). This method is based on the use of special antibodies that bind to IgG in the patient's blood and allow for the measurement of its concentration. The results of the ELISA can be used to establish a diagnosis and select treatment methods.

The value of IgG testing is also demonstrated in the detection of specific antibodies to individual antigens, such as allergens. This is important for identifying specific allergens to which a patient may have an allergic reaction. For example, if a patient is suspected of having an allergy to certain foods, testing for specific IgG antibodies can help determine which foods are causing the allergic reaction and eliminate them from the patient's diet.

It is also important to note that immunological studies, including IgG level measurements, can be used to monitor the effectiveness of immunotherapy treatment, as well as to determine the degree of risk of relapse of immunological diseases.

In summary, measuring total IgG and specific IgG antibodies are important tools in immunoallergy diagnostics. These studies help to establish a diagnosis, determine the degree of activity of allergic reactions, and monitor the effectiveness of treatment. They allow doctors to provide patients with more individualized and effective treatment aimed at improving their health and quality of life.
