At the center of the figure, there is the C-TB skin test, which combines the sensitivity of the in vivo tuberculin skin test (TST) and the specificity of early secretory antigenic target (ESAT-6) and the 10-kDa culture filtrate protein (CFP-10) .Thus, dot-blot assay using MPB64 antigen produced a significantly higher frequency of positive results with infected serum samples than with uninfected serum samples; it also produced a significantly higher frequency of positive results with serum samples from active disease than with those from inactive disease. In the last years, resistant strains of the etiological agent, Mycobacterium tuberculosis, have emerged, thus demanding more triage tests to identify active pulmonary TB (PTB) patients and to evaluate their disease severity.Schlagwörter:Publish Year:2021Systematic Screening For Tb
