Three immunoglobulin tests

The immunoglobulin panel test (IgG, IgM, IgA) is a routine blood test that measures the levels of three major proteins in the serum. IgG is one of the most important components of the immune system and helps the body defend against attacks from foreign harmful bacteria, viruses, and other potentially harmful substances. IgM is generally considered the first line of defense and actively participates in the body's immune response against pathogens. IgA is a naturally occurring antibody primarily found in mucosal linings of the digestive tract and in sweat, playing a role in protection against infections. The immunoglobulin panel test helps physicians assess immune status and thereby provide effective antiviral and anti-infective treatment strategies.
