Table 2. Improved Diagnostic Accuracy Achieved by Combining Detection of MTBK_24820-Specific Immune Responses.

Antigen	Group	Analyte	Sensitivity (%)	Specificity (%)
MTBK_24820	Active TB vs. control	IL-6	23.1	95.4
		IL-6+IFN-α	38.5
		IL-6+IFN-α+CXCL10	65.3
	Active TB vs. LTBI	IFN-α	25.0	100.0
		IFN-α+CXCL10	63.5

TB, tuberculosis; LTBI, latent TB infection; IFN, interferon; IL, interleukin; CXCL10, C-X-C motif chemokine.
