Beside this, how do you know if you test positive for tuberculosis?
A skin test is the only way to tell if you have TB infection. The test is "positive" if a bump about the size of a pencil eraser or bigger appears on your arm. This bump means you probably have TB infection. Other tests can show if you have TB disease.
What is considered a positive TB test?
A positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease. Other tests, such as a chest x-ray and a sample of sputum, are needed to see whether the person has TB disease.
How long does it take to get the results of a TB test?
If a person does not return within 48-72 hours for a tuberculin skin test reading, a second test can be placed as soon as possible. There is no contraindication to repeating the TST, unless a previous TST was associated with a severe reaction.
