About the test
This test measures total IgG, IgA, and IgM. Elevated IgG, IgA, and/or IgM levels are seen in hypergammaglobulinemia, chronic inflammatory conditions, and lymphoproliferative diseases. Decreased levels are associated with hypogammaglobulinemia and immunodeficiency states.
Included biomarkers & Reference ranges
| Biomarker | Reference range |
|---|---|
| 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. | — |
Reference ranges vary by lab, age, and sex (M/F). Your report shows your exact range. Click any biomarker to see its optimal range and what your results mean.
