IGHE and allergic bronchopulmonary aspergillosis: Considering that there is no conclusive study on the specificity and sensitivity of detection of A. fumigatus-specific IgG and IgE performed concurrently in the same set of patients, we aimed to find whether detection of A. fumigatus specific IgG or IgE by immunoassay-methods would perform better in diagnosing ABPA in this systematic review.
