Abstract
Tuberculosis (TB) is a communicable disease that continues a significant threat to global public health threats, and is one of the leading causes of death worldwide. The World Health Organization (WHO) has estimated that in 2021, TB caused the deaths of 1.6 million people globally, with an estimated 191,000 (range 119,000–264,000) deaths occurred due to multidrug-resistant or rifampicin-resistant tuberculosis (MDR/RR-TB). 1 Global Tuberculosis Report 2022 World Health Organization, Geneva2022 Google Scholar A recent paper by Priti Kambli and colleagues highlights that C-reactive protein has good diagnostic accuracy for pulmonary TB among symptomatic adults. 2 Calderwood CJ Reeve BW Mann T Palmer Z Nyawo G Mishra H Ndlangalavu G Abubakar I Noursadeghi M Theron G Gupta RK Clinical utility of C-reactive protein-based triage for presumptive pulmonary tuberculosis in South African adults.

Nevertheless, there are certain differences in diagnostic efficiency, coverage of anti-TB drugs, and the corresponding drug-resistance gene loci among different diagnostic assay kits.
