Immunoglobulin G

Immunglobulin G (IgG) binds to antigens and triggers antigen catabolism. Low levels occur in immunodeficiency syndromes, whereas high levels are observed in severe infections and autoimmune diseases.

Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
