TB skin tests (TST/Mantoux) should generally be avoided by individuals with a previous severe reaction (blistering, necrosis) to the test, those with documented prior positive tests or TB treatment, and generally, people at low risk for infection. Blood tests (IGRA) are preferred for those with a BCG vaccine history.

What is the number one cause of tuberculosis?
The primary cause of tuberculosis (TB) is a bacterium called Mycobacterium tuberculosis.

Is TB 100% contagious?
Active TB disease in the lungs or throat can be infectious. This means the germs can spread to other people. TB disease in other parts of the body, such as the kidney or spine, is usually not infectious. People with active TB disease are most likely to spread it to people they spend time with every day.
What is the biggest symptom of TB?
