What is an antibody, and how do IgG and IgE antibodies differ?
An antibody is a special type of protein produced by the body’s immune system in response to foreign bodies (such as viruses, bacteria and toxins). They are produced by white blood cells called B-Lymphocytes in order to protect the body against these foreign substances. IgE antibodies are a type of antibody mostly found in the skin, nose, lining of airways and lungs, and are usually produced in classical allergies. IgG antibodies are the type of antibodies that the Lab 21 food intolerance test checks for. It has been shown by various studies, that if foods producing high IgG levels are eliminated from the diet, the symptoms of food intolerance can be reduced.
