TB Test for Work, School, or Healthcare Clearance

3 min read

A tuberculosis (TB) test is a common requirement for employment, school enrollment, health care workers, volunteer programs, and other clearance processes. If you have been asked to complete a TB test, you may have the option to choose between a TB skin test and a TB blood test, depending on the organization’s requirements.

TB testing helps identify whether a person has been exposed to the bacteria that causes tuberculosis. While a positive test does not necessarily mean a person has active TB disease, screening is often used as part of workplace, school, or health care clearance programs.

Why Is a TB Test Required?

Many employers, schools, universities, hospitals, and health care facilities require TB testing as part of their onboarding or clearance process. This is especially common in settings where individuals may work closely with patients, students, residents, or other members of the public.

A TB test may be requested for:

  • New employment requirements
  • Nursing school and medical school enrollment
  • Health care worker clearance
  • Volunteer programs
  • Clinical rotations and internships
  • College or university admissions
  • Certain immigration or travel requirements

The specific testing requirement may vary by organization.

Types of TB Tests Available

There are two commonly used methods for TB screening.

TB Skin Test

A TB skin test involves placing a small amount of testing solution just beneath the skin of the forearm. The test site must be examined by a health care professional 48 to 72 hours later.

Because the results must be read in person, the TB skin test typically requires two visits.

Users can schedule a TB Skin Test through LabFinder.

TB Blood Test

A TB blood test, often called a QuantiFERON-TB Gold test, uses a blood sample to measure the body’s immune response to tuberculosis bacteria.

Unlike a skin test, the blood test generally requires only one appointment because the sample is collected and sent directly to the laboratory for analysis.

Which TB Test Should You Choose?

The correct test depends on the requirements provided by your employer, school, hospital, or program.

Some organizations accept either a TB skin test or a TB blood test. Others may specifically require one type of screening.

A TB blood test may be a convenient option for individuals who prefer a single appointment or who may have difficulty returning for a follow-up visit. A TB skin test may be appropriate when specifically requested by the organization requiring clearance.

If you are unsure which test is needed, it is a good idea to confirm the requirement before scheduling.
