Positive skin test: This means the person’s body was infected with TB bacteria. Additional tests are needed to determine if the person has latent TB infection or TB disease.
Negative skin test: This means the person’s body did not react to the test, and that latent TB infection or TB disease is not likely.
There is no problem in repeating a TB skin test. If repeated, the additional test should be placed in a different location on the body (e.g., other arm).
The TB skin test is the preferred TB test for children under the age of five.
