What does it mean to be tested positive for tuberculosis

A positive test for pulmonary tuberculosis generally refers to the detection of Mycobacterium tuberculosis infection in the body by sputum, bronchoscopy, pleural effusion, etc. If this happens, the patient is advised to seek medical attention promptly.

1. Reasons

1. Sputum: Sputum is a general term for respiratory secretions, mainly composed of mucus, serous fluid, and cells. When the human body is invaded by Mycobacterium tuberculosis, it stimulates the body to produce an immune response, resulting in a large number of lymphocyte infiltration, resulting in the formation of caseous necrotic foci and eventually the formation of cavities;

2. Bronchoscopy: When performing bronchoscopy, the doctor will insert a bronchoscope into the patient's oral cavity or nasal cavity, and then use special instruments to observe the condition of the airway, and can take a small amount of tissue for pathological examination to determine whether there is tuberculosis pathogen infection;

3. Pleural effusion: Because tuberculous pleurisy is a common extrapulmonary tuberculosis disease, it is more common in the elderly population in clinical practice, mainly because of a chronic inflammatory disease caused by low body immunity. During the onset of the disease, it can cause symptoms such as chest pain, cough and sputum, fever, and in severe cases, difficulty breathing.

2. Treatment

For people diagnosed with pulmonary tuberculosis, they need to take anti-tuberculosis drugs for treatment according to the doctor's instructions, such as rifampicin capsules, isoniazid tablets, etc., and if necessary, they can also be combined with nebulized inhalation to help improve symptoms. In daily life, we should also pay attention to a light diet and avoid eating spicy and stimulating foods, so as not to aggravate the condition.
