Immunoglobulin G, Sublcass 4

The Immunoglobulin G (IgG) Subclass 4 test measures the level of IgG subclass 4 in the blood, which is one of the four subclasses of IgG antibodies. IgG is the most abundant antibody type in the bloodstream and plays a critical role in the immune response by neutralizing pathogens, facilitating their removal, and providing long-term immunity.This test is particularly useful in assessing immune function, diagnosing specific immunodeficiencies, and monitoring conditions associated with IgG4 levels. Understanding IgG subclass 4 levels can help healthcare providers tailor treatment approaches for patients with complex immune responses or related disorders.
