The IgE (Immunoglobulin-E) test is a blood test used to measure the levels of IgE antibodies in ... the blood. These antibodies are produced by the immune system in response to allergens, parasites, and certain infections. Elevated IgE levels may indicate allergies, asthma, or parasitic infections. The test helps doctors diagnose allergic reactions and immune system disorders.

• Allergic conditions such as asthma, hay fever, or food allergies.
• Unexplained skin rashes, eczema, or chronic hives.

• Autoimmune diseases or immune deficiencies, to evaluate immune system function.
