A Positive TB Skin Test indicates potential exposure to tuberculosis, while a Negative TB Skin Test suggests no detectable TB infection.
Positive TB Skin Test vs. Negative TB Skin Test

Key Differences

A Positive TB Skin Test, also known as a tuberculin skin test, shows an immune response to the bacteria causing tuberculosis. This suggests a potential TB infection. In contrast, a Negative TB Skin Test indicates that there is no significant immune response detected, suggesting the absence of TB infection.

The Positive TB Skin Test results in a raised, red bump at the test site, indicating TB exposure. Conversely, a Negative TB Skin Test typically shows no reaction or a very small reaction at the site of the test.

A Positive TB Skin Test does not necessarily mean active tuberculosis; it can also indicate a latent or past infection. On the other hand, a Negative TB Skin Test usually means the individual has not been infected with TB bacteria or the body has not yet mounted an immune response.

Further tests, like a chest X-ray or sputum test, are often required after a Positive TB Skin Test to confirm active TB infection. In the case of a Negative TB Skin Test, these additional tests are usually not required unless there are symptoms or a high risk of exposure.
