- Immunoglobulin A (IgA) One of your main antibody classes, concentrated in mucous membranes (gut, respiratory tract). Low levels are linked to recurrent infections; also checked before certain other antibody tests, like celiac panels.
- Immunoglobulin G (IgG) Your most abundant antibody class, providing long-term immune memory against past infections. Low levels can point to an immune deficiency.
- Immunoglobulin M (IgM) The antibody class your body produces first in response to a new infection. Elevated levels often indicate a recent or acute infection.
