Using the pathological results of tissue biopsy specimens as gold standard, we ploted the receiver operating characteristic (ROC) curve to determine the optimal cut-off value of mNGS species-specific read number (SSRN) of <jats:italic>Aspergillus<\/jats:italic> in bronchoalveolar lavage fluid (BALF)for IPA.
