Abstract:

China is one of the high-burden country for both tuberculosis (TB) and Mycobacterium tuberculosis (MTB) infection, implementing preventive intervention among populations under high risk of MTB infection and active disease development is an important component of TB control in China. The tuberculin skin test (TST) has been widely used for MTB infection testing and played an important role in assistant diagnosis of TB and high-risk populations monitoring, even though it’s result might be affected by multiple factors including BCG vaccination, environmental non-tuberculosis mycobacteria (NTM) infection and host immune status. Given the national conditions and the epidemiological characteristics of MTB infection in China, such influences could be controlled by innovating application strategy to guarantee the advantages of TST on MTB screening in big populations. In addition, with respect to the characteristics of various target populations, more detailed protocols on operation and result interpretation should be developed based on systematic studies to improve quality assurance of TST.
