TB Testing Requirements by Age

TB testing requirements for children in the immigration medical examination vary based on age and risk factors:

• Children under 2 years of age: generally not required to undergo TB testing
• Children aged 2 to 14: may require TB testing based on country of origin and individual risk factors
• Children 15 and older: follow adult TB testing requirements (IGRA blood test required)

How TB Testing Is Performed in Children

For children who require TB testing, the IGRA (interferon-gamma release assay) blood test is the preferred method. It requires a single blood draw and does not require a return visit for reading.

In some cases, a tuberculin skin test (TST) may be used instead of or in addition to the IGRA. The civil surgeon will determine the appropriate test based on your child's age, country of origin, and clinical situation.

Country of Origin and Risk Factors

TB testing requirements for children aged 2 to 14 may depend on the child's country of origin and individual risk factors. Children from countries with higher TB prevalence may be more likely to require testing. Our civil surgeon will evaluate your child's specific situation and advise on the appropriate testing.

What a Positive TB Test Means for a Child

A positive TB test in a child does not automatically prevent them from obtaining a green card. The civil surgeon will evaluate whether the child has active TB disease or latent TB infection (LTBI). Active TB disease requires treatment before the application can proceed. LTBI is not a ground of inadmissibility but may require follow-up with a healthcare provider.
