IgG is the most abundant antibody in blood and carries long-term immunity from past infections and vaccines; IgA protects the mucous membranes of the gut, airways and mouth. Measuring both quantitatively is the core of an immune-status work-up: low levels help explain recurrent sinus, ear or chest infections and point toward a primary or acquired immune deficiency (selective IgA deficiency is the most common), while high levels can accompany chronic infection, liver disease or autoimmune conditions. This Labcorp version measures IgG and IgA; if you can reach a Quest patient service center, the three-class Immunoglobulins Panel adds IgM for less.
