The sensitivity of bronchoalveolar lavage fluid (BALF) mNGS was significantly higher than BALF culture (81.9% vs. 27.0%, p&amp;lt;0.001) and BALF galactomannan (GM) (81.9% vs. 55.8% (GM\u22651.0 cutoff value), p&amp;lt;0.001). The specificity of BALF mNGS was 92.2%, which was similar with BALF culture (98.5%) and BALF GM (94.7%). The combination of BALF mNGS and GM could increase the sensitivity to 88.7%, and had great negative predictive value (NPV, 92.3%). The sensitivity of blood mNGS was significantly higher than serum GM (58.8% vs. 16.7%, p&amp;lt;0.001).
