Screening Tests for Infants, Children, and Adolescents
Tuberculosis Tests
A Screening for TB using a skin test (tuberculin test) or blood test (interferon-gamma release assay [IGRA]) should be done if Children have been exposed to tuberculosis (eg, to an infected family member or close contact). They have had a family member with a positive tuberculin test. They were born in or recently traveled to a high-risk country (countries other than the United States, Canada, Australia, New Zealand, or Western and North European countries). Their parents or close contacts are new immigrants from a high-risk country or have been recently incarcerated. IGRA is preferred for children who are considered unlikely to return to have their skin test read or for those who have received the BCG vaccine, which can cause a false-positive skin test result.
