Clinical Info
This test aids in the diagnosis of allergic bronchopulmonary aspergillosis (ABPA) and is not appropriate for diagnosing invasive aspergillosis. A positivity cutoff of 40 μg/mL was established based on a comparison study to precipitin assay results. Note that elevated specific IgG concentrations to Aspergillus fumigatus are not disease specific and could be found in healthy individuals. Results must be interpreted in the context of patient's clinical, laboratory, and radiologic findings, and in concordance with current practice guidelines.
