Abstract:

In order to achieve the goal of “End Tuberculosis by 2035”, it is urgent to develop new detection methods. Mycobacterium tuberculosis cfDNA (MTB-cfDNA) can indicate the presence of pathogens and is an attractive biomarker for tuberculosis (TB) diagnosis and treatment monitoring. Easily accessible MTB-cfDNA in urine and/or blood can be used to detect both pulmonary and extrapulmonary TB in any age group. The diagnostic performance of MTB-cfDNA in fluid samples such as pleural effusion, ascites and cerebrospinal fluid is higher than that of genomic DNA assays such as GeneXpert MTB/RIF. Research on cfDNA as a TB biomarker is still in its infancy, larger and clinical studies including more comprehensive patient types are needed to evaluate the utility of cfDNA in TB diagnosis. With further optimization of detection methods, cfDNA testing may improve TB diagnosis and become a “game changer”.
