Who Needs It

Who Needs TB Testing and Titers?

Tuberculosis (TB) screening is a mandatory requirement for all USCIS Form I-693 immigration physicals for applicants two years of age and older. The required test is an IGRA (Interferon-Gamma Release Assay) blood test, which is more accurate than traditional skin tests and is not affected by previous BCG vaccinations.

In addition to immigration requirements, healthcare workers, teachers, and individuals traveling to high-risk areas frequently require routine TB testing and immunity titers (such as MMR and Varicella) to prove immunity to infectious diseases.

Important Information

Understanding Titers and Immunity

Important information regarding immunity testing.

What is a Titer?

A titer is a laboratory blood test that checks for the presence and level of antibodies to a specific disease, proving you are immune.

Why Not Revaccinate?

While revaccinating is safe, titers can prevent unnecessary shots if your body already has sufficient immunity from past exposure or vaccines.

USCIS Requirements

For immigration purposes, if you have lost your vaccination records, a blood titer is the acceptable way to prove to USCIS that you are immune.
