Allergy Testing


  1. What is IgE in blood allergy testing?

    IgE is the antibody certain white blood cells produce in response to an allergen. A specific IgE alerts the body that it's been exposed to a foreign substance (allergen) and, therefore, determines whether or not you have an allergy to a particular food.

  2. How accurate is a food allergy panel?

    The accuracy of a food allergy blood panel has been reported to be between 85% and 98%. This means that an IgE blood test is usually accurate and will provide you with relevant information about whether or not you have allergies.

  3. How do you select the foods to include in your food allergy panel?

    The chosen foods in the panel are all foods with a documented prevalence of causing allergic reactions, which can result in one or more medical problems caused by eating these specific foods. Some of these foods are:

    • Peanuts
    • Almonds
    • Eggs
    • Sesame seeds
    • Shrimp
    • Walnuts
    • Wheat

    If your results are positive for any food allergies, speak to your doctor and dietitian to explore treatment options and dietary changes that can prevent recurring reactions.

  4. Do I need to visit a doctor?

    No doctor visit needed.

  5. How do I get my results?

    You get your results via email as soon as they are available.

Allergies are a reaction by the body's immune system to harmless substances that it sees as harmful. The allergy-causing substances are called allergens.

Your immune system is your body's natural defense against infection and other foreign material. Before you can have a reaction to a particular substance, your immune system must first be sensitized to it. This happens in an earlier contact with the substance. Once sensitized, your body will react every time you have contact with that substance. Many substances can cause an allergic reaction. The most common are pollen, mold, animal dander, dust and dust mites, latex, medicines, insect stings and foods.
