Venous Blood Test 🩸

2 Biomarkers - Allergy, Immunoglobulin E (IgE)

See if you could be allergic to Codfish, Cow’s milk, Eggs, Kiwi, Peanut, Sesame, Soya, Wheat. A blood test that measures biomarkers is a diagnostic procedure that involves analyzing a sample of blood to evaluate various components or substances. These biomarkers are used to understand the body's condition, detect diseases, or assess immune system function. In the context of allergies, two significant biomarkers to look at are Allergy and Immunoglobulin E (IgE).

FAQ’s

  • 1. Allergy Biomarkers (e.g., Specific IgE)

    • Purpose: This test helps in diagnosing allergies by identifying substances (allergens) that might trigger an allergic reaction in the body.

    • How it works: The test measures the levels of specific antibodies called Immunoglobulin E (IgE) that are produced in response to allergens. When an allergen (like pollen, dust, or pet dander) enters the body, the immune system releases IgE antibodies, which can then trigger allergic reactions.

    • Results: Higher levels of specific IgE indicate an allergic reaction to a particular substance. For example, high IgE levels to pollen suggest an allergy to pollen.

    2. Immunoglobulin E (IgE) Test

    • Purpose: The total IgE test measures the overall level of immunoglobulin E (IgE) in the blood. IgE plays a critical role in the immune system, particularly in allergic reactions and fighting off parasitic infections.

    • How it works: IgE is produced by the immune system in response to allergens. When exposed to an allergen, IgE binds to it and triggers the release of histamine, leading to symptoms of allergies (e.g., itching, swelling, hives, or asthma).

    • Results: Elevated total IgE levels can indicate an increased susceptibility to allergies. It may also help identify individuals at higher risk of developing allergic conditions, such as asthma or rhinitis.

    In summary, Allergy biomarkers and IgE testing help to assess allergic responses, with specific IgE targeting allergens and total IgE reflecting the overall allergy tendency. These tests guide physicians in diagnosing and managing allergies effectively.

  • Our test is ideal as part of an initial investigation screen if you have signs of IgE-mediated allergies, such as hives, redness of the skin, vomiting, and lip or facial swelling, which develop quickly after exposure to a nut or seed allergen.
