The Total IgE test measures the level of Immunoglobulin E (IgE) in the blood. IgE is an antibody produced by the immune system in response to allergens. Elevated IgE levels are associated with allergic reactions, asthma, and certain immune disorders.
Purpose of the Test:
•Diagnose allergic conditions: Identifies allergic reactions to substances like pollen, dust, or food.
•Evaluate asthma and eczema: Helps determine the role of IgE in chronic allergic conditions.
•Detect parasitic infections: Elevated IgE levels may indicate parasitic infestations.
•Monitor immune system disorders: Assesses conditions like allergic bronchopulmonary aspergillosis or hyper-IgE syndrome.
Conditions Indicated by Abnormal Levels:
•High IgE Levels:
•Allergic conditions: hay fever, asthma, eczema, or food allergies.
•Parasitic infections.
•Immune system disorders (e.g., hyper-IgE syndrome).
•Certain cancers like lymphoma or multiple myeloma.
•Low IgE Levels:
•Not clinically significant in most cases, but may occur in rare immune deficiencies.
Key Notes:
•Elevated total IgE levels indicate the presence of an allergic or immune response but do not specify the exact allergen.
