Measurement of a Tuberculin Skin Test ReactionTwo to three days after getting a tuberculin skin
test, the size of any bump at the site is measured. Your risk of having TB is
used along with the size of the bump to determine whether the test is: - Positive, meaning you have been infected with TB
bacteria.
- Negative, meaning you have not been infected with TB
bacteria or your body cannot respond to the protein injected because of a
weakened immune system.
The test cannot tell if you have a latent (inactive) infection
or an active infection that can be spread to others. ByHealthwise Staff
