Total IgE

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.
