How What Does a Normal TB Skin Test Look Like Actually Works
A TB skin test, also known as the Mantoux test, is a simple and non-invasive procedure that involves injecting a small amount of tuberculin into the skin on the forearm. The test works by measuring the body's immune response to the bacteria that cause TB. If the person being tested has been infected with TB, their immune system will react to the tuberculin, causing a characteristic skin reaction. The reaction is usually read 48-72 hours after the test, and the results are interpreted as follows:
- A negative reaction indicates no infection* A positive reaction suggests past or present infection
