Immunoglobulin E (IgE) Test – Diagnosing Allergies and Immune Response
The Immunoglobulin E (IgE) Test measures the level of IgE antibodies in the blood, which are produced in response to allergens. High IgE levels are often associated with allergic reactions and asthma. This test can help diagnose allergic conditions and evaluate sensitivity to specific allergens.
Indications for IgE Test:
● Suspected allergies: To determine if allergies are the cause of symptoms like rashes, swelling, or itching.
● Asthma diagnosis: To check for allergic triggers of asthma symptoms, including wheezing, coughing, and shortness of breath.
● Eczema and food allergies: To identify possible allergens causing skin rashes, gastrointestinal discomfort, or other symptoms.
Normal Range:
● IgE: 0–100 IU/mL (varies by age and laboratory).
Abnormal Test Significance:
● High IgE levels: Suggest allergic reactions, asthma, or atopic dermatitis. Elevated levels may also indicate parasitic infections.
● Low IgE levels: Rare, but can indicate immune deficiencies or the absence of allergic sensitization.
Management Based on Results:
● For high IgE levels: Treatment typically includes antihistamines, corticosteroids, or allergy immunotherapy(allergy shots).
● For specific food allergies: Patients are often advised to avoid trigger foods and may benefit from epinephrine injections in case of severe reactions.
Price in India:
● Approx. ₹1,500 – ₹3,500 for the IgE test.
