IGHE and asthma: A recently published study explored potential biomarkers cut offs able to distinguish asthma from ABPA: no one of the biomarkers alone, including BEC, total IgEs, and specific IgEs demonstrated to be accurate enough, but a combination of the three yielded a specificity of 100%, with cut offs being 2347 IU/mL for total IgE, 1.91 kUA/L for AF specific IgE, and 507 cells/μL for BEC [76].
