Immunoglobulins IgG IgM IgA Blood Test

About this test

The body's defence mechanism (immune system) consists of several classes of antibodies. Another name for these antibodies is immunoglobulins (Ig). Examples are IgA, IgE, IgG and IgM. If the defence mechanism is weakned then the body finds it harder to fight infections leading to recurrent infections and chronic illness.

IgA prevents allergens, bacteria and viruses from sticking to the mucous membrane which could otherwise cause infection or inflammation.

IgG constitutes 80% of the body's antibody content. In the case of secondary immune reactions (repeated contact) the body switches to the production of IgG and is an important antibody in the defence against bacteria and viruses.

IgM is the first antibody formed in an immune reaction and is mainly involved in reactions against bacteria and viruses.

Who is this test for?

This test is individual's who get recurrent infections especially of the respiratory tract, the stomach or who suffer from constant diarrhea.

Tests Included


Total Protein represents the sum of albumin and globulin. Abnormal levels can indicate malnutrition as well as a liver or kidney disorder. 

Albumin is made mainly in the liver and helps to keep the blood from leaking out of blood vessels. It also helps carry some medicines and other substances through the blood and is important for tissue growth and healing.

Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and inflammation. It can also occur in kidney conditions such as nephrotic syndrome and diabetes.

Raised levels are usually caused by dehydration.

Globulin consists of different proteins and is made by the liver and the immune system. Certain globulins bind with haemoglobin while others transport metals, such as iron, in the blood and help fight infection.
