Get Tb Risk Assessment Worksheet 2020-2024

The risk assessment should be administered at least once. Persons can be screened for new risk factors at subsequent preventive health visits. Because IGRA has increased specificity for TB infection in persons vaccinated with BCG, IGRA is preferred over the TST in these persons.

The purpose of this tool is to identify adults with infectious tuberculosis (TB) to prevent them from spreading disease. •

Test for LTBI using a Mantoux tuberculin skin test (TST) or an -Gamma Release Assay blood test (IGRA) (e.g., QuantiFERON®-TB Gold or T-SPOT®), unless an appropriately documented,1,2 negative test dated within the past 90 days or appropriately documented positive test result is available.

There are two kinds of tests used to detect TB bacteria in the body: the TB skin test (TST) and TB blood tests. A positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease.

Have you ever had a positive TB skin test? Have you ever had close contact with anyone who was sick with TB? Have you ever been vaccinated with BCG?

The purpose of this tool is to identify adults with infectious tuberculosis (TB) to prevent them from spreading disease. Do not repeat testing unless there are new risk factors since the last negative test.

* Persons may be tested on the basis of local guidance, epidemiology, and for regulatory reasons. ** Evaluate for active TB disease with a chest x-ray, symptom screen, and if indicated, sputum AFB smears, cultures and nucleic acid amplification testing. A negative TST or IGRA does not rule out active TB disease.

What happens during a TB screening? You may get a TB screening test at your provider's office, a health clinic, or hospital. You will have either be a TB skin test or a TB blood test, depending on your health and medical history. TB skin tests are used more often, but blood tests for TB are becoming more common.
