# Immunoglobulins, Quantitative, IgA, IgE, IgG, IgM

> This test measures the levels of four specific types of antibodies, which are proteins your immune system creates to fight bacteria, viruses, and allergens. It helps show whether your body is producing enough protection against infection or if the immune system is overactive due to allergies or inflammation. These results assist doctors in ruling out immune deficiencies, autoimmune issues, and certain chronic disorders. However, this test does not identify the specific germ causing an illness or diagnose a condition by itself.
