In this study, high anti-ARC IgG and anti-TBGL IgA in Beijing TB infected patients, as well as high anti-Ag85B IgG and anti-TBGL IgG in Non-Beijing patients, could offer a sensitivity of 75.0% and a specificity of 77.8% for detecting Beijing MTB infection in diagnosed ATB. The gene discussed is ARC; the disease is tuberculosis.
