Immunoglobulin E-mediated food allergies among adults with allergic rhinitis

Peanut and shrimp were the most common foods encountered in adults with allergic rhinitis. Peanut was best in predicting other food allergies. Total IgE levels with inhalants plus peanut provided the optimal combination of SE, SP, PPV, and NPV. In vitro testing may be important to identify and prevent anaphylaxis to foods in adults.
