Description:Course #WB2556
In this module, you will learn about targeted testing and the diagnosis of latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. Targeted testing is a TB control strategy that is used to identify people who have LTBI, are at high risk for developing TB disease, and would benefit from treatment. LTBI is diagnosed with an interferon-gamma release assay (IGRA) or the Mantoux tuberculin skin test (TST).
It is important to medically evaluate people who have symptoms of TB disease; if they are found to have TB disease, they need treatment to be cured and to help stop the transmission of TB to others. For this reason, the diagnosis of TB disease is crucial to controlling the spread of TB in homes and communities. In most cases, TB disease is diagnosed with certain laboratory tests. For patients who may have pulmonary TB disease, a chest x-ray is also useful for diagnosis
