Despite the fact that out of 11 antigen-antibody tests only anti-Ag85B IgG showed higher response in non-Beijing TB patients than in Beijing TB patients (p < 0.05), the combination of anti-Ag85B IgG, anti-ACR IgG, and anti-TBGL antibodies tests could yield 75.0% sensitivity and 78.8% specificity for detecting Beijing MTB infection in ATB individual. This evidence concerns the gene ACR and tuberculosis.
