  • What is Total IgE & Why Do We Test for It?: Allergy Blood Tests

    IgE or Immunoglobulin E is considered a type of antibody that helps determine type I hypersensitivity in the body. It includes food allergies, sinusitis, allergic asthma, and even atopic dermatitis. Hence, getting an IgE test is crucial for all age groups as it can help rule out your allergic symptoms.

    Some people have had allergic reactions to different substances since childhood, while others develop allergies over time.

    IgE Blood Test: What is it, When one Needs it, and How is it Performed?

    Your doctor may advise you to get an allergy blood test done if you have an allergic reaction to any of the below allergens:

    • Dust
    • Pollen
    • Hay
    • Nuts
    • Fish
    • Eggs
    • Mold
    • Animal Dander
    • Medications like penicillin.

    Allergy blood tests typically help to check the number of antibodies or Immunoglobulin E in your immune system. Every time an allergen triggers a reaction, your immune system causes allergic symptoms as a sign of threat to your body. Total IgE tests not only rule out the causes of your allergy but also check to see if your immune system is strong enough to fight away allergens.

    And if you're wondering what allergic symptoms you might face, here are a few:

    • Sneezing
    • Hives on the body.
    • Stuffy or runny nose.
    • Itchy or watery eyes
    • Diarrhea
    • Coughing
    • Wheezing
    • Vomiting

    Allergy Blood Test: What do the Test Results Mean?

    Your healthcare professional will draw some blood from your arm and send it to the laboratory as a sample to check your IgE count and what triggers your allergies. IgE allergy tests do not require any preparation and thus can easily be undertaken.

    Once your test results come in, check for the following:

    • A high total IgE test can indicate that you have some allergy; however, the result will never indicate the exact cause or symptom.
    • A specific IgE test, if high, will mean you're allergic to the allergen for which you got tested, but it doesn't indicate the severity of the allergy. 

    Depending on your test results, your healthcare professional will devise a treatment plan to ensure that your allergic symptoms subside. It is also recommended to carry emergency epinephrine or an Epipen or medications that can curb allergies.
