The only WHO-recommended rapid diagnostic test (RDT), the Alere Determine TB Lipoarabinomannan Ag (AlereLAM) has suboptimal sensitivity. A laboratory-based electrochemiluminescence LAM assay (EclLAM) is the current sensitivity benchmark for RDT development and the gold standard for urinary LAM detection. We assessed the diagnostic accuracy of an ultra-sensitive, Plasmonic Fluor-linked Immunosorbent LAM assay (PFLISA-LAM) compared to Sputum Xpert MTB/RIF, sputum culture and urine EclLAM.</p><p><strong>Methods: </strong>We developed and evaluated the assay performance of PFLISA-LAM. Two sub-studies were conducted using banked urine samples: 1. Preclinical study using 337 well-characterised urine samples for cutoff determination and initial evaluation of the performance of PFLISA-LAM compared to sputum Xpert MTB/RIF and culture. 2. A Diagnostic accuracy assessment study using 77 blinded samples to evaluate the performance of PFLISA-LAM compared to EclLAM versus microbiological reference standard (MRS, Xpert positive and/or culture positive).</p><p><strong>Findings: </strong>PFLISA-LAM has a limit of detection (LOD) of 0.84 ± 0.9 pg/mL when detecting purified LAM spiked in urine. In the preclinical study, the optimal assay cutoff was determined to be 1.7 pg/mL. The sensitivities of PFLISA-LAM and sputum Xpert MTB/RIF compared to culture were 51% (95% confidence interval [CI]: 43%-59%) and 62% (95% CI: 53%-70%). The specificities of PFLISA-LAM and Xpert MTB/RIF were 99% (95% CI: 96%-100%) and 100% (95% CI: 100%-100%). Combining PFLISA-LAM and Xpert MTB/RIF test data, an improved sensitivity of 76% (95% CI: 69%-83%) can be achieved. In the diagnostic study, the sensitivities of EclLAM and PFLISA-LAM assays were 42% (95% CI: 27%-59%) and 73% (95% CI: 56%-85%).
