Positive Result: A positive TST result means that you have been infected with TB bacteria. However, it does not necessarily mean that you have active TB disease. Further testing, such as a chest x-ray and sputum test, is needed to determine if you have active TB.
Negative Result: A negative TST result means that you are unlikely to have been infected with TB bacteria. However, it does not completely rule out TB infection, especially if you have a weakened immune system.
Induration Size Interpretation:
- ≥ 5 mm: Considered positive in people with HIV, recent contacts of TB cases, people with organ transplants, and people with suppressed immune systems.
- ≥ 10 mm: Considered positive in people with some medical conditions (such as diabetes, kidney disease, and cancer), injection drug users, and people who have recently immigrated from countries with high TB rates.
- ≥ 15 mm: Considered positive in people with no known risk factors for TB.

8.2. Interpreting Interferon-Gamma Release Assay (IGRA) Results

The IGRA result is reported as either positive, negative, or indeterminate.

Positive Result: A positive IGRA result means that you have been infected with TB bacteria. Further testing is needed to determine if you have active TB disease.
Negative Result: A negative IGRA result means that you are unlikely to have been infected with TB bacteria. However, it does not completely rule out TB infection, especially if you have a weakened immune system.
Indeterminate Result: An indeterminate IGRA result means that the test was unable to determine whether you have been infected with TB bacteria. In this case, you may need to repeat the test or undergo further evaluation.

8.3. Interpreting Chest X-Ray Results

The chest x-ray results can reveal signs of TB in your lungs, such as cavities, lesions, or enlarged lymph nodes.

Normal Result: A normal chest x-ray result means that there are no signs of TB in your lungs. However, it does not completely rule out TB infection, especially if you have latent TB.
Abnormal Result: An abnormal chest x-ray result may indicate active TB disease. Further testing, such as a sputum test, is needed to confirm the diagnosis.

8.4. Interpreting Sputum Test Results

The sputum test results can confirm the presence of TB bacteria in your sputum.

Positive Result: A positive sputum test result means that you have active TB disease. You will need to start treatment with antibiotics to kill the TB bacteria.
