IMMUNOGLOBULIN E (IgE)

Immunoglobulin E

The Immunoglobulin E (IgE) test measures the level of IgE antibodies in the blood.

IgE antibodies are part of the immune system and play a key role in allergic reactions. When the body is exposed to allergens, such as pollen, pet dander, or certain foods, IgE levels can increase, triggering symptoms like itching, swelling, and difficulty breathing. This test helps in diagnosing allergic conditions, including asthma, eczema, and hay fever, as well as identifying specific allergens that may be causing a person's symptoms.

Elevated IgE levels indicate an allergic response, while normal levels suggest that allergies are unlikely. By identifying specific allergens, the IgE test can guide healthcare providers in developing effective management and treatment plans to reduce or eliminate allergy symptoms.
