To compare the diagnostic potential of IP-10 with IFN-γ, AUC values for IFN-γ assessed in serum or QFT whole blood cultures stimulated with M. tb antigens for comparisons: (1) HC vs. TB+LTBI+NMP, (2) TB vs. LTBI+NMP+HC, (3) TB+LTBI vs. HC+NMP, and (4) TB+NMP vs. HC+LTBI, were also determined (Table 4). The gene discussed is CXCL10; the disease is tuberculosis.
