How to know TB drug resistance

To know whether tuberculosis drug resistance, can be through sputum TB culture and drug sensitivity test, molecular biology detection, clinical symptoms and treatment response, imaging examination and other methods, comprehensive judgment helps to improve diagnostic accuracy. Drug resistance is determined by culturing TB bacteria and testing their susceptibility to multiple anti-TB drugs. 2. Molecular biological tests: GeneXpert MTB/RIF test, which can quickly detect TB bacteria and detect rifampicin resistance at the same time. 3. Clinical symptoms and treatment response: 4. Imaging examination: Chest X-ray or CT examination helps to understand the situation of lung lesions and judge the treatment effect. It should be noted that the diagnosis of drug-resistant tuberculosis requires a combination of methods, doctors will choose the appropriate detection means according to the specific situation. At the same time, for tuberculosis patients, should follow the doctor's advice standard treatment, regular review, in order to improve the cure rate, reduce the occurrence of drug resistance.Key information: TB drug resistance diagnosis methods include sputum culture and drug sensitivity test, molecular biology detection, clinical symptoms and treatment response, imaging examination, etc., comprehensive judgment is helpful to improve the accuracy of diagnosis. Patients should follow the doctor's advice to standardize treatment and review regularly.
