Introduction
A negative culture for Mycobacterium tuberculosis in sputum does not rule out the possibility of pulmonary tuberculosis. Pulmonary tuberculosis must be diagnosed based on clinical symptoms and appropriate imaging studies. There are various diagnostic approaches for tuberculosis, and clinically, multiple testing methods are typically used together to establish the diagnosis. First, chest X-ray or CT scan is used to detect and assist in diagnosing pulmonary tuberculosis, and to guide further treatment.
Pulmonary tuberculosis can be diagnosed by sputum culture for Mycobacterium tuberculosis. If the sputum culture test is positive for Mycobacterium tuberculosis, a diagnosis of pulmonary tuberculosis can be confirmed. Pulmonary tuberculosis is typically a chronic disease caused by bacterial infection in the body. Imaging examinations alone cannot serve as definitive diagnostic evidence. Of course, tests such as the PPD skin test and interferon-gamma release assays (IGRAs, e.g., T-SPOT) can only be used as supplementary diagnostic tools. So, what is the most accurate way to diagnose pulmonary tuberculosis?

Even if the sputum culture for Mycobacterium tuberculosis is negative, pulmonary tuberculosis cannot be completely ruled out. The diagnosis of pulmonary tuberculosis requires evaluation of clinical symptoms along with corresponding imaging studies. There are multiple testing approaches for tuberculosis, and clinically, a combination of various methods is usually employed for diagnosis. First, chest X-ray or CT scans are used to detect and assist in diagnosing pulmonary tuberculosis and to guide subsequent treatment.
This disease is contagious to some extent and may cause pathological changes in multiple organs. When infected, individuals should identify the source of infection, consume nutritious foods, and eat protein-rich foods to strengthen their immunity.
In daily life, maintain a regular diet, avoid spicy and irritating foods, refrain from overeating, and avoid staying up late. We hope this response has been helpful to you. Wishing you good health and happiness.
