Diagnostic yield of tongue swab testing for tuberculosis is comparable to sputum testing, suggesting a cost-effective alternative in high-burden areas.
Tongue swab-based molecular testing with MiniDock MTB achieved non-inferior diagnostic yield compared with sputum-based molecular testing. These findings support scale-up of swab-based platforms as a cost-efficient alternative, particularly where sputum collection is challenging or smear microscopy remains the primary diagnostic method.
