IgE Total Test Overview What is an IgE Total Test? The total IgE test detects the presence of IgE antibodies in your blood, indicating an increased risk of allergic reactions. Tests for allergen specific IgE particles are then used to determine which substances are causing your allergic reactions. Who Needs an IgE Test? If you have allergy symptoms, your doctor may recommend allergy testing. These are some examples: An allergen-specific immunoglobulin E (IgE) test is a blood test that detects the presence of various IgE antibodies in a person's blood. Allergen-specific IgE tests are sometimes used to diagnose and manage food allergies. In some cases, they can also help with an environmental allergy diagnosis. How are the results of IgE Total tests interpreted?
Immunoglobulin E (IgE) is one of the five immunoglobulin classes, distinguished by the presence of the epsilon heavy chain. It is the most
When the immune system responds to a foreign material from food, contact, or inhalation into the lungs, allergies develop. Allergies are the sixth most common chronic ailment in the United States, affecting more than 50 million people. Many people visit their healthcare providers for testing due to allergies as a typical cause. Anaphylactic allergies have the potential to be fatal in rare circumstances. A blood test that measures immunoglobin is one way to help diagnose allergies (IgE). IgE is an antibody that aids the body in its defence against foreign bodies such as bacteria and viruses. An allergen specific IgE blood test can detect the presence of various IgE antibodies. If they are abnormally high or low, it may indicate that the person has a more serious health problem.
Total IgE is a blood test that measures the number of antibodies produced by your immune system in response to allergens. IgE (immunoglobulin E) is an allergic reaction-causing antibody. When you are exposed to an allergen—a normally harmless substance that your immune system interprets as dangerous, such as peanuts—your body produces specific IgE antibodies designed to recognize that allergen in the future. When you are re-exposed to the allergen, your immune system produces many allergen specific IgE particles to identify and eliminate the allergen.
Some allergies may be detected using an allergen specific IgE test, which can include:
If skin testing for allergies is not possible, your provider may order an allergy blood test. Skin testing involves the application of allergens to or into your skin:
Preparation and Procedure of an IgE Total Test
There is no need to prepare specifically for the IgE Total Test. You simply need to ensure that you have obtained all the necessary information from your doctor and that you understand the procedure and medications completely.
Patients with suspected diseases associated with elevated levels of total immunoglobulin E (IgE), such as allergic disease, primary immunodeficiencies, infections, malignancies, or other inflammatory diseases, are evaluated. Patients with suspected allergic bronchopulmonary aspergillosis and Identification of omalizumab (anti-IgE) therapy candidates are evaluated for diagnostic purposes.
Normal range: Fluorescent standard units are used to report the results of your IgE test (FSU). If the measurement is less than 0.01 FSU, there is no IgE to be found.
Higher range: IgE concentrations that are higher than normal are typically associated with allergic illness. Infections, inflammatory illnesses, primary immunodeficiencies, and malignancies are just a few of the conditions that can cause increases in the quantity of circulating total serum IgE. Except for allergic bronchopulmonary aspergillosis, total IgE levels are not very useful in the diagnostic assessment of individuals with suspected allergic diseases (ABPA). Patients with asthma or cystic fibrosis are more likely to get ABPA, which is a hypersensitive reaction to the fungus Aspergillus. The diagnostic criteria for ABPA include an increase in total IgE, albeit the precise diagnostic concentration depends on the patient.
If further laboratory and clinical requirements are met, elevated total IgE values may be compatible with the diagnosis of allergic bronchopulmonary aspergillosis. Total IgE values between 30 and 700 kU/L may help identify patients who should get omalizumab therapy and may also help with therapeutic dosage calculations.
Low serum IgE has been linked to:
IgE Total Result Interpretation:
The results of an IgE Total Test should be carefully interpreted considering how a patient is presenting. High levels of total IgE can be found in malignancies, parasite infections, immune-related illnesses, and allergic diseases.

Frequently asked questions
Total IgE counts the number of antibodies in your blood that your immune system has created in response to allergens. IgE, an antibody, is the substance that starts an allergic reaction. Your immune system develops a lot of IgE particles that are particular to the allergen to recognize and get rid of it when you are exposed to it again.
Immunoglobulin E (IgE), an antibody produced by the body's immune system to combat any threat the body detects, is measured by the test IgE antibodies are linked to a variety of allergic reactions.
Usually, within a few days, the test results are out. The results are usually available in one to two weeks and are reported numerically.
IgE Total Test carries very little risk. Where the needle was put, you might suffer some little discomfort or bruise, but most symptoms will heal soon.
