What type of testing does an Allergist perform?

An allergist specializes in diagnosing and treating allergic conditions, which includes performing tests that determine the underlying causes of allergic reactions. This involves specific testing methods such as skin prick tests, blood tests, and challenge tests designed to identify allergens that provoke symptoms in patients, like asthma, hay fever, and food allergies. By focusing on the basis of these reactions, allergists can tailor treatments to help patients manage their allergies effectively and improve their quality of life. The other options do not fall within the scope of an allergist's practice, as they pertain to different medical specialties, such as cardiology or endocrinology for diabetes, or radiology for imaging.
