Immunoglobulin E (IgE), a component found in your blood, is measured during an allergy blood test. Your body produces the antibody IgE. You could have higher levels of IgE in your blood than usual if you have allergies.
A frequent, chronic disorder involving your immune system is allergies. Your immune system produces antibodies to defend against bacteria, viruses, and other pathogens that might harm you. Your immune system misinterprets one or more innocuous items, such as pollen, as a threat leading to allergies. Your immune system produces IgE antibodies to combat the "threat." This is what causes your allergy symptoms.
Allergens are harmless substances that can trigger allergies. Typical allergens consist of:
- Pollen
- Dust
- Mold
- Animal dander
- Certain medicines, such as penicillin.
- Certain foods, including nuts and seafood.
The symptoms of an allergy vary and they may include sneezing,itching as well as asthma or the potentially fatal anaphylactic shock.
