How to check tuberculosis drug resistance

TB drug resistance can be determined by drug sensitivity testing, genetic testing and clinical observation. TB drug resistance can be determined by laboratory tests, mainly including the following methods: 1. Drug sensitivity testing (Drug susceptibility test): This is the most commonly used method to diagnose TB drug resistance. By culturing TB bacteria and adding different anti-TB drugs to the culture medium, the sensitivity of TB bacteria to drugs can be observed. According to the drug susceptibility test results, it is possible to determine whether TB bacteria are resistant and which drugs are resistant. 2. Genetic testing: In recent years, gene detection technology has also been used to detect drug-resistant genes in tuberculosis. By detecting mutations in specific genes in tuberculosis, it is determined whether there are drug-resistant mutations. 3. Clinical observation: During treatment, closely observe the symptoms, signs and treatment response of patients. If the patient is not sensitive to the treatment regimen, symptoms persist or worsen, or adverse drug reactions occur, the possibility of drug resistance needs to be considered. Tips: The above content is for reference only, and the specific examination methods and diagnosis need to be evaluated and selected by professional doctors according to the specific conditions of the patient. If TB drug resistance is suspected or /confirm/ied, seek medical attention promptly and follow your doctor's advice for further testing and treatment.
