What are IgA and IgG?

IgA and IgG are Immunoglobulins which are produced naturally by the human body.

IgA is Immunoglobulin A that protects or guards mucosal surfaces of the respiratory and gastrointestinal tract and are a
critical first line of defence against foreign pathogens.

IgG is Immunoglobulin G which is present in all body fluids and is very important in fighting bacterial and viral infections.
