Allergic rhinitis test is more sensitive than the skin prick test but is more often positive in people that do not have symptoms to that allergen. Even if a person has negative skin-prick, intradermal and blood tests for allergies, he/she may still have allergic rhinitis, from a local allergy in the nose. This is called local allergic rhinitis.

Allergic bronchopulmonary aspergillosis placing global burden at around 4.8 million people affected. The Eastern Mediterranean region had the lowest estimated prevalence, with a predicted case burden of 351,000; collectively, the Americas had the highest predicted burden at 1,461,000 cases. These are likely underestimates of total prevalence, given the exclusion of CF patients and children from the study, as well as diagnostic testing being limited in less developed regions. Allergic bronchopulmonary aspergillosis Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterised by an exaggerated response of the immune system (a hypersensitivity response) to the fungus "Aspergillus" (most commonly "Aspergillus fumigatus"). It occurs most often in
