Abstract

Five of 10 paucibacillary leprosy patients were Quantiferon Gold (Q-G) positive with negative chest X-rays. Forty multibacillary leprosy patients were negative. Reports have shown 100% cross-reactivity of ESAT6 and CFP10 between Mycobacterium leprae and Mycobacterium tuberculosis. The Q-G test cannot detect latent tuberculosis in patients with leprosy.
