USCIS has stopped accepting the TB skin test
Since October 1, 2018, the tuberculin skin test (TST) is no longer accepted for US Citizenship and Immigration Services (USCIS) immigration exams (1). All US civil surgeons must now use a TB blood test (interferon-gamma release assay or IGRA) as the initial screening method when a test for cell-mediated immunity to TB is required. This requirement aligns with the most current CDC recommendations which state that IGRA testing is strongly preferred for those who are BCG-vaccinated.

Learn how to interpret and manage IGRA results, and why this change is an important step in the CDC’s march toward TB elimination in the US. Dr. Oladele is the medical director of county-wide services for the DeKalb County Board of Health, Georgia, where he directs medical screening of 1,000–2,000 refugees annually.
