An allergist is a physician with advanced education and training in the evaluation and treatment of allergy, asthma, and immune related disorders in children and adults. Allergists complete residency training in either Pediatrics or Internal Medicine prior to acceptance into an Allergy/ Immunology fellowship training program. During the Allergy/Immunology fellowship, the physician receives specialty training on the performance and interpretation of allergy skin testing, lung function studies, and formulation of allergen immunotherapy ("allergy shots"). The emphasis of training is to identify a person's specific allergy triggers, to help minimize exposure to these allergens, and to develop an individualized treatment plan including prevention, medications, and allergen desensitization.
