Allergy Diagnosis and Treatment

A medical specialist or allergist can diagnose an allergic condition through skin testing (puncture testing). This test helps determine what a person is allergic to by causing an allergic reaction in a controlled environment. Avoidance of an allergy is the best treatment but some allergies are unavoidable. In this case, the doctor may prescribe medications such as antihistamines, leukotriene modifiers and inhaled steroids or inhalers. For more long-term relief of allergies, allergy shots are recommended.
