When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies. These antibodies are made by the plasma cells.

There are 5 classes of immunoglobulin, IgG, A, M, D and E, determined by their heavy chains. In normal serum, approximately 80% is IgG, 15% IgA, 5% IgM, with 0.2% IgD and trace IgE. Laboratory testing for immunoglobulins in peripheral blood typically detects the 3 …

What is an immunoglobulins blood test? This test measures the amount of immunoglobulins in your blood. Immunoglobulins are also called antibodies. Antibodies are proteins that your immune system makes to fight germs , such as viruses and bacteria .

Doctors may check immunoglobulin levels to see if a person has an infection or is protected from getting an infection (is immune to it). Doctors also use immunoglobulin tests to help diagnose immunodeficiencies (when the immune system isn't working as it should).

Reference ranges according to age for immunoglobulins (IgG, IgA, and IgM) and IgG subclass concentrations (IgGSc) vary depending on the region, source population, applied method, and time. For this reason, these values need to be updated for an accurate diagnosis in the same ethnic group and same region.
