Total IgE
Understanding Total IgE
What is Total IgE?
Total IgE, also known as the Immunoglobulin E test, helps in determining allergic reactions and immune responses by measuring the level of Immunoglobulin E (IgE) antibodies present in the blood. It detects multiple allergies, ranging from seasonal allergies, food allergies, and insect sting allergies to parasitic diseases and certain immune illnesses.
Immunoglobulin E (IgE) is an antibody found in the immune system that protects the body from potential danger or allergies. The immune system produces numerous different kinds of IgE, all of which target a substance that would cause an allergy, including pollen, dust mites, food allergens, and insect bites. When the immune system is exposed to an allergen, it induces the production of IgE antibodies, which attach to other immune cells.
The Total IgE test measures how much IgE antibodies are in the blood. It doesn't, though, tell you what kind of IgE antibody. You might need an IgE test if you have symptoms of asthma or allergies, such as watery or itchy eyes, swelling, coughing, shortness of breath, skin rash, congestion, sneezing, etc. For individuals with asthma caused by allergy, testing may assist in determining the appropriate treatment and appropriate dosage. The Total IgE test can be required if you experience symptoms of an immune disorder or a parasitic infection, including abdominal pain, cough, diarrhea, dry skin, hives, etc.
No fasting is needed for this test. You may eat and drink normally according to your routine. Also, inform your doctor about any medications you may be taking, as some of these medications (like antihistamines) may influence your test results if taken prior to this test.
Test result ranges may vary slightly across laboratories. Speak with your doctor to understand what your result means. Based on the findings, they may recommend lifestyle changes or medications to manage your health.
What is Total IgE used for?
The Total IgE test can be done:
- If you experience allergy symptoms such as itchy or watery eyes, swelling, shortness of breath, skin rash, congestion, or sneezing.
- To track and monitor treatment progress and effectiveness
- If a parasitic infection or allergic respiratory disease is suspected.
- In individuals with a family history of allergies.
What does Total IgE measure?
The Total IgE (Immunoglobulin E) test is used to quantify the total level of IgE antibodies in your blood. Immunoglobulins are antibodies (proteins) secreted by plasma cells (immune cells) when the body identifies a dangerous foreign substance like bacteria, viruses, or allergens. There are five basic forms of immunoglobulins: IgA, IgG, IgM, IgD, and IgE. Of these, IgE plays a primary role in allergic reactions to allergens such as pollen, dust, pet dander, mold, latex, some foods (such as eggs, peanuts, or strawberries), or insect stings.
Unlike other antibodies, IgE is primarily associated with immune responses to allergenic substances, such as plant pollen, latex, pet dander, mold, eggs, peanuts, bee venom, and strawberries. Typically, IgE is present in tiny amounts in the blood. When the immune system encounters an allergen, it triggers the production of IgE antibodies. The Total IgE test measures the concentration of these IgE antibodies in the blood, providing insights into the presence and severity of allergies.
