What is the name of the test used to screen for tuberculosis?

The Mantoux Test is the correct name of the test used to screen for tuberculosis (TB). This test involves the intradermal injection of a purified protein derivative (PPD) of the TB bacterium into the skin, usually on the forearm. After 48 to 72 hours, the injection site is examined for any reaction, indicating whether the individual has been exposed to the TB bacteria.

The Mantoux Test is specifically designed to measure the immune response to the antigen, thereby indicating whether the person has a latent or active TB infection. It is a crucial tool in public health for early detection and prevention of TB transmission.

Other tests mentioned do not serve the same purpose as the Mantoux Test. For instance, while the skin prick test is used for various allergies and some other infections, it is not specific for tuberculosis. The two-step test is typically used in circumstances where an individual has had a previous negative tuberculin skin test, potentially resulting in more accurate readings, but it is a variant of the Mantoux Test rather than a distinct tuberculosis screening method. Likewise, while an X-ray test can help visualize lung abnormalities and may be used in conjunction with other tests to diagnose active TB, it is not a screening test for latent
