What is a TB Test?
A TB test, or tuberculosis test, is a diagnostic tool used to determine if a person has been infected with the bacteria that cause tuberculosis. TB tests are essential for early detection and treatment of this potentially serious disease.
Types of TB Tests
There are primarily two types of TB tests: the Mantoux tuberculin skin test (TST) and the Interferon-Gamma Release Assays (IGRAs). The TST involves injecting a small amount of tuberculin into the skin and observing the reaction. IGRAs, on the other hand, measure the immune response to TB bacteria in the blood.
Why TB Tests Are Important
Early detection of tuberculosis through TB tests can help prevent the spread of the disease and ensure timely treatment. Regular screening is particularly crucial for individuals at higher risk, such as healthcare workers and those with weakened immune systems.
