How to interpret the results of immunological tests for the diagnosis of tuberculosis in child

: New available immunologic tests for tuberculosis (TB) diagnosis are Interferon-gamma release assay (IGRA). In adults these tests showed a higher specificity than tuberculin skin test (TST) but their superior sensitivity compared to TST sensitivity has not been proved yet. In children, interpretation of results remains disputed, especially in those <5 years. Hereby we report the most recent literature data for use and interpretation of IGRA is results in children.
