Classification of cells in sputum

Microscopic examination of sputum is to observe white blood cells, red blood cells, epithelial cells and dust cells, as well as fibers, crystals, fats, parasites, etc. in the sputum, which helps to diagnose the diagnosis of certain characteristic diseases of the respiratory system. Leukocyte neutrophils are found in respiratory tract inflammation, such as bronchitis, pneumonia, etc.; eosinophilia is seen in patients with chronic bronchial asthma, allergic bronchitis, paragonimiasis, and tropical eosinophilia. Basic Information Specialist classification: Respiratory examination classification: sputum examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not take saliva as a specimen, and send the specimen immediately after collection. Normal value A small amount of neutrophils, epithelial cells and dust cells. Clinical significance 1, leukocyte neutrophil increase in respiratory tract inflammation, such as bronchitis, pneumonia, etc.; eosinophilia found in chronic bronchial asthma, allergic bronchitis, paragonimiasis, tropical eosinophilia patients. 2, red blood cell sputum can appear in large numbers, a small amount of red blood cells can be seen in purulent or mucopurulent sputum. 3, epithelial cell squamous epithelial cells increased in acute laryngitis, pharyngitis; ciliated columnar epithelial cells increased in bronchial asthma, acute bronchitis; round epithelial cells increased in the lung inflammation. 4. Pigment cells (macrophages or alveolar epithelial cells containing a pile of yellow or brown hemosiderin particles). Seen in patients with long-term congestion and heart failure in the lungs. A large number of cases appear in idiopathic pulmonary hemosiderosis. 5, elastic fibers indicate destructive lesions of the lung parenchyma, such as lung abscess, lung cancer, progressive tuberculosis. 6, spiral body (Cushman spirochete) found in bronchial asthma, asthmatic acute or chronic bronchitis, tuberculosis and lung cancer. 7, crystallization Cholesterol crystals are found in chronic tuberculosis, lung abscesses, empyema, tumors or liver abscesses that break into the bronchi. Fatty acid crystals are found in lung gangrene, bronchitis, tuberculosis, etc. Bilirubin crystals are more common in lung abscesses. The spindle-shaped crystal (Charcotic crystallization) is found in bronchial asthma and paragonimiasis. 8, parasites can be found in paragonimiasis, eggs of the lung cysticercosis and amoeba trophozoites. 9, tumor cell lung cancer. Precautions The results of the sputum examination are accurate. It is very important to take the samples. Do not take saliva as a specimen. The specimens should be sent immediately after collection to avoid cell and bacteria autolysis. Inspection process Sputum check. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks No adverse reactions.
