Interstitial pneumonia is diagnosed.

Tests for interstitial pneumonia include lung function tests, HRCT, blood tests, lung biopsies, and other tests, depending on the patient. Interstitial pneumonia is a diffuse disease of the lungs that mainly involves the interstitial tissue, alveoli, and bronchioles. There are many types and complex etiologies. For suspected patients or high-risk groups, the following are some common tests: 1. Pulmonary function test: This is the basic method to evaluate lung function, including vital capacity, total lung volume, residual volume and other indicators. For interstitial pneumonia, restrictive ventilation dysfunction and diffusion function may occur. 2. High-resolution CT (HRCT): HRCT has important value in the diagnosis of interstitial pneumonia. It can provide information on the fine structure of the lungs and help to detect lung inflammation, fibrosis.3. Blood tests: The doctor may check the patient's blood routine, C-reactive protein, erythrocyte sedimentation rate and other indicators to assess the inflammatory response and overall health.4. Lung biopsy: This is an important method to determine the cause and diagnosis of interstitial pneumonia. Lung tissue is obtained by percutaneous lung puncture or thoracotomy for pathological examination. 5. Other tests: Depending on the circumstances, the doctor may recommend further tests such as blood gas analysis, autoantibody testing, and virus testing. It should be noted that the diagnosis of interstitial pneumonia requires a combination of clinical manifestations, imaging, and laboratory results. In addition, for some special groups, such as the elderly, immunocompromised, long-term smokers, etc., more attention should be paid to the screening and prevention of interstitial pneumonia. If cough, breathing difficulties, chest pain and other symptoms occur, should seek medical attention promptly, and inform the doctor of the relevant medical history and risk factors. In short, interstitial pneumonia examination methods are diverse, doctors will choose the appropriate examination items according to the specific situation of the patient, to determine the diagnosis and formulate personalized treatment plan. Early diagnosis and treatment are essential to improve the prognosis.
