  • a The results of analysis of 44 serum samples from confirmed tuberculosis patients are presented. The detection of antibodies to Irep-28 is compared to conventional diagnostic tests, including culture, chest radiography, and the commercial antibody-detection lateral flow device Mycotest. The results show the high degree of correlation of the detection of anti-Irep-28 with culture and chest X-ray compared to the Mycotest.
