The Total IgE test measures the overall amount of Immunoglobulin E (IgE) antibodies in the blood. IgE is a type of antibody produced by the immune system in response to allergens. Elevated levels can indicate an allergic reaction or parasitic infection. This test is used to diagnose allergic conditions, monitor allergy treatments, and assess the likelihood of allergic reactions. It's particularly useful when combined with specific IgE tests to identify particular allergens. The test can also help diagnose certain immune system disorders or parasitic infections.
A low Total IgE level (below the reference range) is generally not considered clinically significant. It does not necessarily indicate any health issues or the absence of allergies. Some individuals with allergies may still have normal or low IgE levels. A low IgE level might be seen in certain rare immune deficiency disorders, but diagnosis would require additional testing and clinical correlation.
An elevated Total IgE level (above the reference range) suggests an increased likelihood of allergic conditions or other disorders that stimulate IgE production. High levels are commonly associated with allergic rhinitis, asthma, atopic dermatitis, and food allergies. However, it’s important to note that elevated IgE can also occur in non-allergic conditions such as parasitic infections, certain immune deficiencies, and some types of cancer. Further testing and clinical evaluation are necessary to determine the specific cause of elevated IgE levels.
