This study evaluates the sensitivity and specificity of an enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against Mycobacterium tuberculosis antigen. Twenty seven of the 35 patients with pulmonary tuberculosis had positive serology with an antibody titre of 10 nineteen of them had positive serology with an antibody titre of 100. All the 27 patients with positive serology were either smear or culture positive or both. Twenty six of the 35 control group had negative serology and 9 had positive serology with an antibody titre of 10. The test has a sensitivity of 77.14% and a specificity of 74.29%.
