What is a tb test for a job?

A TB test, also known as a tuberculosis skin test, is a test that determines if a person has been infected with the bacteria that causes tuberculosis. It involves injecting a small amount of fluid, called PPD, into the skin on the underside of the forearm. The area is then checked two to three days later for a reaction, which typically appears as a raised bump.

Many employers require a TB test as a condition of employment in certain fields or industries, such as healthcare or education. The test is designed to protect both the employee and their colleagues or patients from the spread of tuberculosis. It is also required for certain immigration and travel purposes.

It is important to note that a positive TB test does not necessarily mean a person has active tuberculosis. Additional testing and evaluation are needed to confirm a diagnosis. Individuals who test positive may be referred for further testing and treatment, which typically involves taking antibiotics for several months.
