How to detect pneumonia

Pneumonia can be diagnosed by chest X-ray/CT, blood tests, sputum smears and cultures, and other tests. Pneumonia can be diagnosed by the following tests: 1. Chest X-ray or CT examination: can help doctors to see whether there is inflammation, infiltration or consolidation in the lungs and other abnormalities. 2. Blood tests: including white blood cell count, C-reactive protein, procalcitonin and other indicators. These tests can help determine the presence of infection and the degree of inflammation. 3. Sputum smears and cultures: If symptoms such as coughing and expectoration occur, the doctor may ask the patient to cough up sputum for smears and cultures to detect the presence of bacteria, fungi, and other pathogens. 4. Other tests: Such as virus detection, antibody detection, drug sensitivity test, etc., may be selected according to specific circumstances. The comprehensive application of these test methods can improve the diagnosis rate of pneumonia, and determine the type of pathogen, so as to select the appropriate treatment plan. It should be noted that for some special groups, such as the elderly, immunocompromised patients or patients with other underlying diseases, pneumonia symptoms may not be typical, and test results may not be specific. Therefore, doctors will make comprehensive judgments and evaluations according to specific circumstances. If pneumonia symptoms such as fever, cough and dyspnea occur, seek medical attention promptly and carry out relevant examinations and treatment according to the doctor's advice. At the same time, good personal hygiene habits, such as frequent hand washing and wearing masks, can help prevent the occurrence and spread of pneumonia.
