The allergy diagnosing process consists of the following stages: evaluating the relevance of patient's symptoms to allergic causes; recognising allergies; determining a cause-effect relationship between the recognised allergies and the prevalence of the symptoms; assessing the degree of organic or systemic impairment resulting from the allergic disease. In case of allergy, accurate diagnosis requires that careful history is taken and supported with suitable additional testing. The testing methods used to identify the allergens, such as skin tests, are of particular relevance, and if their result are ambiguous, the serum should be tested for the presence of antigen-specific IgE antibodies. In case of food allergy and intolerance, food challenge tests are the main tool to confirm the diagnosis. In respiratory allergies sometimes it is necessary to perform bronchial and nasal challenge tests.
