Using a cut-off of 0.100, plasma K/T ratio gave a diagnostic sensitivity of 94% (CI 82-95), specificity of 90% (CI 80-91), PPV 85% and NPV 98%. A receiver operating characteristic curve (ROC) gave an area under the curve of 0.95 (CI 0.92-0.97, p 0.0001). plasma K/T ratio is a sensitive blood-based diagnostic test for active TB disease in pregnant women living with HIV. Plasma K/T ratio should be further evaluated as an initial TB diagnostic test to determine its impact on patient care. plasma K/T ratio is a sensitive blood-based
