Immunoglobulins IgG

Overview:
The Immunoglobulin G (IgG) test measures the level of IgG antibodies in the blood. IgG is the most common type of antibody found in the blood and plays a crucial role in the immune response by protecting against bacterial and viral infections. It is involved in long-term immunity and memory after exposure to pathogens or vaccinations.

What it detects:
This test detects the amount of IgG in the blood. Low levels of IgG may indicate an immune deficiency, leaving the body more susceptible to infections. Elevated IgG levels may suggest an ongoing or previous infection, chronic inflammatory conditions, or certain autoimmune diseases (e.g., rheumatoid arthritis, lupus). It can also be used to assess the body’s response to vaccines.

Who should get it:
Individuals with recurrent infections, suspected immune deficiencies, or autoimmune diseases may need this test. It is also useful for monitoring the immune system in patients undergoing treatment for conditions that affect immunity, as well as for individuals who need to check immunity after vaccination or exposure to infectious diseases.
