Diagnosis of Tuberculosis among Children and Adolescents

The authors discuss the challenging aspects of the diagnosis of tuberculosis in children and adolescents, since there is no gold standard for its diagnosis. The different clinical and radiological presentations and the low bacteriological positivity of tuberculosis in childhood are grounds for confrontation to the present. Immunological tests called inter‐ feron gamma release assays (IGRAs) failed to overcome the tuberculin skin test in prac‐ tice. Advances with nucleic acid amplification tests, on the other hand, have contributed to the diagnosis of tuberculosis among adolescents. Standardized systems for diagnosis can be useful as tools for screening or for decision‐making in childhood tuberculosis.
