What is the allergy blood test?
An allergy blood test checks for the presence of immunoglobulin E antibodies in your blood. Our immune system produces Immunoglobulin E antibodies in response to potential harmful substances such as viruses and bacterias. An allergic person’s immune system produces IgE antibodies in response to a specific allergen even if it is harmless.
What is an allergy?
Allergies appear when your immune system reacts abnormally to certain substances that are typically harmless. It often takes time to develop an allergy to a substance, a person may not experience any allergic reaction after the first exposure to that specific substance.
At a later time, your immune system will recognize that specific allergen, and then begins to produce antibodies in order to attack it. This development is called sensitization.
What are the causes of an allergic reaction?
An allergic reaction appears when allergen binds to the antibodies, and the body releases Immunoglobulin E (IgE). These antibodies fight off foreign and harmful components in the body. When allergens bind to these antibodies, certain cells including basophils and mast cells produce chemicals that stimulate symptoms of the allergic reaction.
Histamine is a chemical which is released by the cells that tightens the walls of the airways and muscles of the blood vessels. This also triggers the lining of the nose to generate more mucus.
