Article Synopsis
  • Tongue swab (TS) sampling combined with quantitative PCR (qPCR) shows promise as an alternative to sputum testing for tuberculosis (TB) diagnosis, although previous studies indicated lower sensitivity.
  • Two strategies were evaluated to enhance sensitivity: one involved centrifugation to concentrate MTB DNA, achieving 83% sensitivity and 100% specificity, while the other utilized sequence-specific magnetic capture, resulting in 90% sensitivity and 97% specificity.
  • These findings suggest that with further development, these methods could lead to more accessible and effective TB testing options.

Background: Annually, about 4000 US children undergo a tracheostomy procedure to provide a functional, safe airway. In the hospital, qualified staff monitor and address problems, but post-discharge this responsibility shifts entirely to caregivers. The stress and constant demands of caregiving for a child with a tracheostomy with or without ventilator negatively affect caregivers.

Tongue swabs hold promise as a non-invasive sample for diagnosing tuberculosis (TB). However, their utility as replacements for sputum has been limited by their varied diagnostic performance in PCR assays compared to sputum. The use of silica-based DNA extraction methods may limit sensitivity due to incomplete lysis of Mycobacterium tuberculosis (MTB) cells and co-extraction of non-target nucleic acid, which may inhibit PCR.

Unlabelled: Tongue swab (TS) sampling combined with qPCR to detect (MTB) DNA is a promising alternative to sputum testing for tuberculosis (TB) diagnosis. In prior studies, the sensitivity of tongue swabbing has usually been lower than sputum. In this study, we evaluated two strategies to improve sensitivity.
