    What is an Immunoglobulin E (Total IgE) Test?

    An Immunoglobulin E (IgE) test measures the level of IgE antibodies in the blood

    IgE is a type of antibody produced by the immune system to defend against foreign substances like viruses and bacteria. However, in some individuals, the immune system also produces IgE antibodies against substances it considers harmful (e.g., pollen, pet dander, or certain foods), triggering an allergic reaction.

    While small amounts of IgE are generally present in the blood, elevated levels may indicate an allergic response. Therefore, a Total IgE test can help identify allergic conditions by measuring the body's immune response to potential allergens. It can also aid in diagnosing parasitic infections and certain immune system disorders that cause elevated IgE levels.

    Preparation for the Immunoglobulin E (Total IgE) Test

    Preparing for a Total IgE test is simple and usually does not require any special precautions like fasting.

    Key Considerations:

    • Inform your doctor about any medications or supplements you are taking, especially antihistamines. It may affect test accuracy, so check with your doctor on whether you should stop taking them before the test

    Immunoglobulin E (Total IgE) Test Procedure

    The Total IgE Blood test is a simple blood test, a quick and minimally invasive procedure, which is usually completed in five minutes. Here’s what you can expect:

    • You will be seated comfortably.

    • An eMedic will locate a suitable vein, usually in the inner elbow area.

    • The area will be cleaned and disinfected to maintain sterility.

    • A small needle will be inserted into the vein, which may cause a slight pinch.

    • Blood will be drawn into a test tube or vial for analysis.

    • After collecting the sample, the needle will be gently removed.

    • A cotton ball or gauze will be placed to stop any bleeding, followed by a small bandage for protection.

    • You can expect to receive your test results online within a few hours or as per the timeline provided by the laboratory you choose.

    The skin prick test for IgE testing is another common method used to identify potential allergens that may be causing allergic reactions. This test is typically performed on the forearm, upper arm, or back and involves the following steps:

    • A small amount of various suspected allergens is placed on the skin's surface.

    • The skin is gently pricked or scratched to allow the allergens to enter just beneath the surface.

    • The healthcare professional monitors the area for signs of a reaction, such as redness, swelling, or itching. Results usually appear within 15 to 20 minutes.

    • Several allergens can be tested at once to assess different sensitivities efficiently.

    Why Take the Immunoglobulin E (Total IgE) Test?

    Your doctor may recommend a Total IgE test if you or your child shows symptoms of allergies, immune system disorders, or parasitic infections. This test helps evaluate the body's immune response and detect underlying conditions

    In cases where allergy testing is needed, either a skin prick test or a blood test may be suggested.

    However, skin testing involves exposing the skin to allergens, which may not be suitable for individuals who:

    • Take medications that may affect test accuracy

    • Have skin conditions that interfere with results

    • Are at risk of a severe allergic reaction (anaphylaxis) from allergen exposure

    For those at higher risk of serious allergic reactions, the Total IgE blood test provides a safer alternative, as it does not require direct exposure to allergens. Additionally, for young children who may find skin testing uncomfortable, a Total IgE Blood test can be a more convenient and safer alternative.

    Who Should Take the Immunoglobulin E (Total IgE) Test?

    You may need an IgE Blood test if you have an allergy. Common allergens that may trigger an immune response include:

    • Pollen

    • House dust

    • Certain foods

    • Latex

    • Mould

    • Pet dander, urine, and saliva

    • Insect bites and stings

    • Certain medications, such as penicillin.

    You may also need this test if you experience :

    • Allergic rhinitis (hay fever): Often triggered by environmental allergens like pollen, pet dander, or mould with symptoms like difficulty breathing, sore throat, itchy or stuffy nose, watery or red eyes.

    • Anaphylaxis: A severe, potentially life-threatening allergic reaction to foods (such as peanuts), insect stings, or other allergens with symptoms like chest tightness, swelling of the tongue and throat, difficulty breathing, dizziness, fainting, and shock.

    Signs That You May Need an Immunoglobulin E (Total IgE) Test

    Your doctor may recommend a Total IgE test if you experience symptoms that suggest an allergic reaction or an immune system response. Common signs that may indicate the need for this test include:

    • Skin reactions: Hives, rashes, or itching

    • Respiratory issues: Sneezing, stuffy or runny nose, coughing, wheezing, or shortness of breath

    • Eye symptoms: Red, itchy, or watery eyes

    • Swelling: Swollen lips, tongue, eyes, or face

    • Gastrointestinal symptoms: Nausea, vomiting, or diarrhoea

    • Chest discomfort: Tightness in the chest or allergic asthma

    If you have persistent or severe allergy symptoms, an IgE test can help identify possible triggers and guide further testing or treatment.

    Normal IgE levels typically range from 0 to 100 IU/mL, but this can vary depending on the laboratory and age. Children often have higher normal ranges than adults.

    Elevated IgE levels can indicate allergic reactions (like asthma, eczema, hay fever, or food allergies), parasitic infections, or certain immune system disorders. In rare cases, high IgE may be associated with conditions like hyper-IgE syndrome.

    Doctors may recommend an IgE test if you experience frequent allergic symptoms, such as sneezing, hives, skin rashes, asthma, itching, or swelling, especially when the cause is unclear.

    While diet doesn’t directly change IgE levels, exposure to allergens through food, air, or environment can trigger an increase. Managing allergies and avoiding known triggers can help maintain stable IgE levels.

    Antihistamines, corticosteroids, and immunosuppressive drugs can influence IgE-related symptoms and may affect allergy testing accuracy. It’s important to inform your doctor about any medications you’re taking before testing.
