Why do we still test for TB?
This test checks to see if you have been infected with tuberculosis, commonly known as TB. TB is a serious bacterial infection that mainly affects the lungs. It can also affect other parts of the body, including the brain, spine, and kidneys. TB is spread from person to person through coughing or sneezing.
Do they still do TB tests?
There are two types of tests for TB infection: the TB skin test and the TB blood test. A person’s health care provider should choose which TB test to use. Factors in selecting which test to use include the reason for testing, test availability, and cost.
What is the most reliable test for TB?
The most commonly used diagnostic tool for tuberculosis is a skin test, though blood tests are becoming more commonplace. A small amount of a substance called tuberculin is injected just below the skin on the inside of your forearm. You should feel only a slight needle prick.
How often does the CDC recommend TB skin testing for direct care employees?
CDC and NTCA do not recommend annual TB testing for health care personnel unless there is a known exposure or ongoing transmission in a health care setting. All health care personnel should receive TB education annually.
Who should not get a TB test?
People who inject illegal drugs. People who are sick with other diseases that weaken the immune system. Elderly people. People who were not treated correctly for TB in the past.
How long do you wait between TB skin tests?
The skin test reaction should be read between 48 and 72 hours after administration by a health care worker trained to read TST results. A patient who does not return within 72 hours will need to be rescheduled for another skin test. The reaction should be measured in millimeters of the induration (firm swelling).
How often are TB tests required?
If you have a negative skin test, you need a repeat test at least once every four years. If you have a documented positive skin test, you must have an initial chest X-ray. After that, you still need to be screened every four years.
