A positive sputum test indicates that the patient’s sputum is infected with Mycobacterium tuberculosis and is likely to be infected with a tuberculosis-like disease, which requires prompt medical attention and timely treatment. If you have a chronic cough, feel discomfort in your lungs, have sputum or breathing problems, and have a positive sputum test, you need to consider the possibility of tuberculosis first. Patients are advised to visit a regular hospital, where doctors combine laboratory tests, medical imaging and clinical manifestations to determine the cause. Tuberculosis is an infectious and malignant disease that can invade many organs as it progresses and even cause complications such as pulmonary heart disease, which can be life-threatening if not treated promptly.
