Although the clinical course of the diseases, chest computed tomography (CT) findings, and immunological tests, such as total IgE, Aspergillus-specific IgG, or IgE and Aspergillus precipitating antibody, are used to diagnose these diseases, in some cases, it may be difficult to distinguish between ABPA and CPA [7,9,13,14]. Here, IGHE is linked to allergic bronchopulmonary aspergillosis.
