About Immunoglobulin g (total)

What is immunoglobulin G?

Immunoglobulin G (IgG) is a type of antibody typically produced by the immune system to protect against pathogens such as bacteria, viruses and parasites. IgG antibodies are the most common antibody found in the blood and offer long-term protection against pathogens after initial exposure. High IgG levels are associated with chronic infections and plasma cell disorders, whereas low IgG levels are associated with hypogammaglobulinaemia.

Why take the test?

This test measures the total level of IgG in the blood. It might be used to investigate chronic infections, plasma cell disorders and hypogammaglobulinaemia.
