TB Testing & Immunity Titers: Who Needs Them and Why?

Are you starting clinicals, beginning a new job, enrolling in school, or completing health screening requirements?

You may be asked to provide documentation of tuberculosis (TB) screening or immunity to certain infectious diseases.

But what exactly are these tests, and why might you need them?

What Is TB Testing?

TB testing helps identify possible tuberculosis infection.

One commonly used option is the QuantiFERON-TB Gold Plus blood test.

What Are Immunity Titers?

Immunity titers are blood tests that measure specific antibodies in your blood. They can help assess evidence of immunity to certain diseases.

Commonly requested tests include:

• Hepatitis B Surface Antibody: Helps assess immunity to hepatitis B.

• MMR Titers: Check antibodies to measles, mumps, and rubella.

• Varicella IgG: Checks antibodies to the virus that causes chickenpox.

Who Might Need These Tests?

Healthcare workers, students, employees, volunteers, and individuals completing specific health screening requirements may be asked to provide these results.

Before You Schedule

Check with the organization requesting your testing to confirm exactly which tests and documentation are required. Requirements vary, and additional evaluation or vaccination records may sometimes be needed.

The bottom line: Whether you're preparing for clinicals, starting a new opportunity, or completing a required health screening, understanding your testing requirements can help you stay prepared.
