Figure 3: Scatter plots of ELISA results using our novel recombinant antigens and the reference antigens.

Recombinant antigens assayed are rSS1, rSS2, rSS3, rSS4, rSS5, Esat-6 and 38 kDa Ag). The serum samples used were from of healthy controls (HC), diseased controls (DC), tuberculosis patient (PTB, EPTB, HIV-TB) and MDR-TB. The scatter plot indicates the antibody level per subject analysed. A dotted horizontal line is included to show the cut-off value for individual antigen.
