Allergen, Tree, Aspen IgE
Also known as: ASPEN
Use
The Allergen, Tree, Aspen IgE test is designed to measure the specific immunoglobulin E (IgE) antibodies to Aspen tree allergens in human serum. It aids in the diagnosis of allergic conditions, such as asthma or rhinitis, that may be triggered by exposure to Aspen tree pollen. The quantitative enzyme immunoassay used in this test is performed by Eurofins Viracor and can assist healthcare providers in identifying an individual's allergic response to Aspen, thereby informing treatment and management strategies.
Special Instructions
This test is processed by a non-ARUP laboratory, specifically Eurofins Viracor. When collecting specimens for multiple tests, separate specimens are required. The test is New York state approved, and compliance is associated with a quantitative enzyme immunoassay methodology.
Limitations
The test has not been cleared or approved by the U.S. Food and Drug Administration, though its performance characteristics have been determined by Eurofins Viracor. Hemolyzed, icteric, or lipemic specimens are considered unacceptable and may lead to inaccurate results. The assay's interpretation categories range from 'Below Detection' to 'Very Strong Positive,' providing qualitative insights into IgE levels against Aspen allergens.
