Immunoglobulin E blood test

Service Description

Immunoglobulin E (IgE) is a type of antibody produced by the immune system. It plays a critical role in the body’s defense against parasites and in allergic reactions. Purpose of IgE 1. Allergic Reactions: IgE is involved in the body’s response to allergens like pollen, dust, food, and pet dander. It binds to allergens and triggers the release of histamine, leading to symptoms such as itching, swelling, and difficulty breathing. 2. Defense Against Parasites: IgE helps combat parasitic infections by activating immune cells like mast cells and eosinophils. IgE Blood Test An IgE blood test measures the total level of IgE in the blood or specific IgE antibodies against certain allergens. Why It's Done - Diagnose Allergies: Identify triggers for food, environmental, or seasonal allergies. - Assess Asthma or Eczema: Elevated IgE is often linked to these conditions. - Detect Parasitic Infections: High IgE levels may indicate a parasitic infection. - Evaluate Immune System Disorders: Rare disorders like hyper-IgE syndrome.
