<s>[INST] How do I know if I have TB? [/INST] TB requires diagnosis from a medical professional. Two tests exist to determine the presence of a TB infection: a TB skin test or a blood test. The presence of an infection does not definitively determine active TB. Chest x-rays, medical evaluation, and sputum sample collection are required to diagnose the presence of active TB disease. A key challenge in ending TB is due to barriers of access to diagnosis, whether through cost or access to healthcare. Stop TB Partnership’s TB REACH and Global Drug Facility (GDF) tackle these issues from all angles, from funding, research, and supply.

Diagnosis of TB in children is extremely difficult and is often recognized only when the child is already critically ill and the disease has spread from the lungs to the brain or other organs. In 2020, 1.1 million children fell ill with TB globally. Fortunately, new technologies are currently being developed to try to identify TB in children. Source: Stop TB.
