Diagnostic accuracy

  1. Tongue swab PCR showed high accuracy for pulmonary tuberculosis
    Rapid PCR testing on tongue swabs shows promise for tuberculosis diagnosis in sputum-scarce patients, with high specificity but limitations in detecting low bacillary loads.
  2. tNGS accurately detected tuberculosis and drug resistance in non-sputum samples
    Nanopore-based targeted sequencing demonstrates 93% sensitivity and specificity for detecting Mycobacterium tuberculosis and drug resistance from non-sputum specimens in multicenter Chinese study.
