Table 3 Performance comparisons between the HS-RTP, the N-RTP, and culture under different conditions, including overall specimens, pulmonary specimens (sputum, bronchoalveolar lavage (BAL) and bronchial washing (BW)), extrapulmonary specimens, AFS-positive specimens and AFS-negative specimens. AFS: acid fast stain; + : positive; − : negative. N: sample size.
