Clinical Significance

Detection of antibodies to specific IgE allergen.

Allergy and diseases caused or complicated by allergy, such as asthma or diseases with symptoms that mimic allergy, are among the most widespread and costly health problems in the world. Traditionally, allergy testing was performed by applying allergens directly to or under the skin. The subsequent appearance of a raised welt indicated sensitivity. However, skin testing carried the risk of serious allergic reaction and was not recommended for young children and or elderly patients. Although many patients continue to undergo skin (scratch) testing, testing of blood samples for allergen antibodies has been recognized as a viable alternative. Blood testing decreases discomfort for patients and can be performed on patients of all ages, including infants and the elderly. Test results aid in distinguishing allergies from other conditions with similar symptoms, such as colds and other respiratory infections. Blood allergen testing determines an individual's sensitivity to a given allergen. The test measures IgE (immunoglobulin E), an antibody circulating in the blood when the body is fighting an allergen. Semi-quantitation of blood antibodies is indicator of a patient’s sensitivity to a specific allergen. Results are reported in kU/L as well as the corresponding Class System. Testing is available for individual allergens or for multi-allergen screens. Multi-allergen screening tests do not identify the specific allergen(s) within a screen that may be responsible for a positive result, but do assist with narrowing the search for causative allergic stimuli. Blood testing can be ordered by the patient’s primary care physician or by an allergy specialist. Test results should always be evaluated in combination with a thorough patient history and physical.
