Immunoglobulin E IgE Test

An Immunoglobulin E (IgE) test is a blood test that measures the level of IgE antibodies in the blood. IgE is an antibody that plays a key role in allergic reactions and is elevated in individuals with allergies or asthma.

The IgE test is often used to diagnose allergies, especially in cases where the symptoms are not clear or when skin prick tests are inconclusive. It can also help determine the specific allergen that is triggering the allergic reaction.

The IgE test is typically performed in conjunction with a medical history and physical examination to accurately diagnose allergies. Depending on the results of the test, healthcare providers can recommend appropriate treatment options, such as allergen avoidance, medications, or allergy shots.
