What is Tuberculosis?
Tuberculosis (TB) is an infectious disease caused by bacteria that spread through the air from person to person. While TB most commonly affects the lungs, it can also impact other areas of the body, including the brain, kidneys, and spine. Without proper treatment, TB can become life-threatening.
There are two main states: latent TB infection (you have TB bacteria in your body but no symptoms, non-infectious) and active TB disease (you have symptoms, can spread it)
Testing helps identify who has been exposed or infected, even if they are not yet sick, so they can get treatment if needed and prevent spread.
What happens if the test is positive or negative?
- Positive results for a skin or blood test means you have likely been infected with the TB bacteria. This does not tell you if it is an active infection. To check for active TB, doctors will often order a TB chest x-ray and sputum test
- Negative results means that no evidence (by that test result) of infection. Sometimes this isn't perfect, for example, a very recent infection might not yet be detected, or immune suppression might reduce response.
What are the side effects of risks of TB tests?
- Very minimal
- Skin test-mild pain, redness, swelling at the injection site
- Blood test- pain or bruising at needle site. Rare allergic reaction possible
How often should I be tested for TB?
This will depend on a person's risk factor. People who work in healthcare, live in high TB burden settings or have certain medical conditions might need regular testing. For most people, they only need to be tested when there is an immediate risk or exposure.
