The use of diagnostic systems for tuberculosis in children

Effective management of tuberculosis (TB) in children and important data of disease burden continue to rely on a clinical approach to diagnosis, as diagnosis of childhood TB is not confirmed in the majority. Many diagnostic scoring systems have been developed to aid with diagnosis. This article reviews the use and evaluation of these approaches.
