From the expert

Antibodies or immunoglobulins play a key role in the body's immune system, helping to protect the body against bacteria, viruses and substances that are recognised by the body as "non-self" and harmful. There are five different classes of immunoglobulins and several subclasses. Each class represents a group of antibodies that has a slightly different role.

This test measures the amount of immunoglobulins A, G, and M (IgA, IgG, IgM) in the blood to detect or monitor an excess or deficiency in one or more of the immunoglobulin classes.

Immunoglobulin M (IgM) – IgM antibodies are produced as a first response to a new "non-self" antigen, providing short-term protection.

Immunoglobulin G (IgG) – Around 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are produced during an initial infection and the body retains a catalogue of IgG antibodies that can be rapidly reproduced whenever exposed to the same antigen. IgG antibodies form the basis of long-term protection against microorganisms.

Immunoglobulin A (IgA) – IgA comprises about 15% of the total lung and stomach secretions, and breast milk. IgA provides protection against infection in mucosal areas of the body.
