Allergen,Individual-AnimalCat DanderSerum

Cat Hair and Dander Allergy Blood Test measures the IgE antibody levels in the blood to detect a cat allergy. Cat allergies are more common than other pet allergies because individuals are not allergic to only cat hair or fur. Instead, many individuals are allergic to the proteins found in cats: saliva, urine, and dander (skin flakes in animal hair or fur).

Cat allergens are easily spread through shedding hair or dander. The cat hair and dander become airborne, and once settled, they are hard to get rid of from soft surfaces, such as clothing, bedsheets, pillows, or linens, furniture (couches, chairs, or mattresses) and carpets.

When an individual with a cat allergy becomes exposed to these allergens, their immune system recognizes the substances as foreign. As a result, it stimulates the plasma cells to produce specific antibodies that combat the invaders. These antibodies cause a chemical known as histamine to be released, triggering an allergic reaction. The allergic reaction may occur within minutes or a few hours after initial exposure to cat allergens and may vary from mild to severe depending on the individual.
