An immunoglobulins blood 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. Your body makes different kinds of antibodies to fight germs in different parts of the body and at different stages of an infection.
An immunoglobulins blood test can help your health care provider diagnose different types of health conditions that may affect your immune system.
