The development of rapid near point-of-care diagnostics utilizing non-sputum specimens is critical for advancing TB control efforts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this multicenter prospective diagnostic accuracy study, 689 consecutive individuals with presumptive TB were enrolled from 3 sites in China. Sputum and tongue swab specimens were collected from all participants for index testing with the LyocartE assay and comparator testing with Xpert Ultra, smear microscopy, and culture. The diagnostic performance of LyocartE for active TB was evaluated against 2 pre-defined reference standards: Xpert Ultra results and the composite microbiological reference (MRS) standard.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among the 689 participants analyzed, LyocartE on sputum demonstrated a sensitivity of 95.2% and specificity of 98.6% against the MRS. For tongue swab specimens compared to sputum Xpert Ultra results, LyocartE sensitivity was 87.4% with a specificity of 99.7%. When evaluated against MRS for tongue swabs, sensitivity was 84.1% and specificity was 99.7%. The diagnostic accuracy of LyocartE remained robust across specimen types, clinical symptoms, and comorbidities. Strong correlation was observed between LyocartE and Xpert Ultra cycle threshold (Ct) values (sputum: r = 0.7476, P &amp;lt; .0001; tongue swab: r = 0.5607, P &amp;lt; .0001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The near point-of-care LyocartE assay offers rapid and accurate TB detection from both sputum and tongue swab specimens. Its performance is comparable to Xpert Ultra on sputum and demonstrates improved sensitivity for tongue swab analysis. Further evaluation in asymptomatic and paucibacillary populations is urgently required to confirm these findings.<\/jats:p>\n
