Various allergy tests are available for diagnosing allergies. These tests are specially selected based on the person's age, complaints, the severity and frequency of symptoms and signs, co-existing diseases, and all medications being used. Choosing the appropriate allergy test is vital for making an accurate and timely diagnosis, and for creating an effective treatment plan. In this process, a detailed consultation with an immunology and allergic diseases specialist should first be conducted. When the specialist makes a preliminary diagnosis of an allergic disease based on the current clinical picture and the patient's characteristics, they will determine the most suitable allergy test for that preliminary diagnosis and individual.
