The Immunoglobulin E Total test (also known as IgE-Total) analyses the concentration of the IgE antibodies in the blood. Antibodies are generally produced by the immune system to combat harmful substances such as viruses and bacteria. However, if you are allergic to something like pollen or dust, your body mistakenly identifies it as harmful and generates IgE antibodies against it. Thus, an IgE test can indicate whether you have an allergy. Normally, there are small amounts of IgE antibodies in the blood. Increased levels of IgE antibodies may suggest that the body is reacting to a perceived allergen, causing an allergic reaction. Additionally, some immune system problems or parasite infections may be indicated by elevated IgE levels.

• You have a skin condition like hives or a rash.

• You are on antihistamines or cannot undergo a skin allergy test.

• You have an immune system issue such as hyper IgE syndrome.

The IgE test measures IgE levels in the blood using the Enzyme-Linked Fluorescence Assay (ELFA) method. The normal IgE test values are listed below:

Clinical Significance

IgE levels tend to rise during childhood and stabilise in the teenage years. As a mediator in allergic responses, IgE is often elevated in patients with atopic dermatitis, allergic asthma, and allergic rhinitis. However, elevated total IgE levels can also occur in several non-allergic conditions, including:

• Immunodeficiency states

• Autoimmune diseases

• Parasitic infections

• Sezary syndrome

• Hodgkin's disease

• Bronchopulmonary aspergillosis

• IgE myeloma

Therefore, discussing the results of your Total IgE test with your doctor is crucial for understanding the causes of elevated IgE in your specific health condition.
