Blood Allergy Test Radio Immunoabsorbent Test Blood
What is this test?
Blood Allergy Test Radio Immunoabsorbent Test Blood is used to test the sensitization of your skin to a specific allergen. This test helps to know the immune response of the body towards the allergen. In this test, your skin is slightly pricked and introduced to a tiny amount of the specific allergen.
What are Antibodies and their types?
Antibodies are the protective proteins produced by the immune system and also known as immunoglobulins. Antibodies are produced when any foreign substance or virus or bacteria enters into the body. These foreign substances are known as antigens. Antibodies recognize and attach to the antigens in order to remove them from the body. There are five (5) subtypes of antibodies and they are IgG, IgM, IgA, IgD, IgE.
When someone is exposed to the specific allergen, the body detects it as a foreign substance and releases the specific IgE antibody. IgE binds to the basophils and mast cells and then recognize the allergen and cause an allergic reaction. IgE binds to the basophils and mast cells.
Why this test is performed?
