Global Tuberculosis Diagnostics Market was valued at USD 2.19 billion in 2023 and is anticipated to witness an impressive growth in the forecast period with a CAGR of 4.50% through 2029. Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis, a bacterium that primarily affects the lungs but can also infect other parts of the body. TB is a contagious disease that spreads through the air when an infected person coughs or sneezes, releasing infectious droplets that can be inhaled by others. It is a major global health concern and has been a significant cause of illness and death throughout history. TB is primarily transmitted through the inhalation of airborne droplets containing M. tuberculosis. It is considered an airborne disease. Close and prolonged contact with an infectious individual is usually required for transmission to occur. Not everyone exposed to TB bacteria becomes ill. In some cases, the immune system can contain the bacteria without causing symptoms. This is known as latent TB infection. People with LTBI do not feel sick, cannot spread TB to others, but they are at risk of developing active TB in the future.

Active TB occurs when the immune system cannot control the bacteria, leading to the development of symptoms. Typical symptoms of active TB include a persistent cough, chest pain, fatigue, weight loss, night sweats, and coughing up blood. TB can also affect other parts of the body, such as the bones, kidneys, and brain, in a form known as extrapulmonary TB. TB diagnosis involves a combination of clinical evaluation, chest X-rays, sputum tests, and molecular tests like PCR. In some cases, a tuberculin skin test or interferon-gamma release assay (IGRA) is used to detect latent TB infection. Advances in diagnostic technologies, including molecular assays, gene sequencing, and point-of-care (POC) tests, have improved the accuracy, speed, and accessibility of TB diagnosis. Early detection of TB is a priority in TB control efforts to prevent the spread of the disease. This focus drives the development and adoption of rapid and sensitive diagnostic methods.
