# Allergen Profile With Total IgE, Respiratory–Area 20

> This test measures the levels of Immunoglobulin E (IgE), a type of antibody your immune system produces when it reacts to common airborne triggers like pollen, mold, dust mites, or pet dander. It helps show whether symptoms such as sneezing, wheezing, or congestion are caused by an allergic reaction to substances found in your specific geographic region. By identifying specific sensitivities, this test helps distinguish between allergic conditions, such as hay fever or asthma, and other respiratory issues like infections. However, a positive result indicates sensitization to an allergen and does not confirm a diagnosis or predict the severity of a future reaction on its own.
