Neutrophil ratio refers to the ratio of neutrophils to total white blood cells and is one of the data in routine blood tests. If the neutrophil ratio is high, but the white blood cells are in the normal range and the body does not have any abnormal symptoms, it is generally considered physiologically high. If the neutrophil ratio is high, the absolute neutrophil value is elevated and the white blood cells are elevated, and there are other abnormal symptoms, then it is considered pathologically high. Physiologically high: Some women may have a temporary high neutrophil ratio due to pregnancy, childbirth, ovulation, etc. In addition, after strenuous exercise and overexertion, or fear, anger, tension and other emotional stimulation, may also lead to high neutrophil ratio, generally no special treatment, regular review can be. Pathological high: 1, acute infections: such as Staphylococcus aureus, hemolytic streptococcus, Streptococcus pneumoniae, dysentery bacillus and other bacterial infections, hemorrhagic fever, epidemic B encephalitis and other viral diseases, can cause neutrophils, leukocytes, resulting in high neutrophil ratio, need to be combined with bacterial culture, pathogenetic examination to identify. For bacterial infections, the main treatment is to use sensitive antibiotics, and in the case of viral infections, symptomatic treatment is usually given. 2. Tissue necrosis: diseases such as intestinal obstruction, acute myocardial infarction, acute pulmonary infarction, etc., as well as severe trauma and large burns may also stimulate the body to increase granulocytes and leukocytes, resulting in a high neutrophil ratio, which can be judged by ultrasound, CT, and arteriography. In the case of acute infarction, timely thrombolytic therapy is required. In case of severe trauma or intestinal obstruction, surgical treatment may be required. 3. Tumor diseases: such as multiple myeloma, liver cancer, gastrointestinal tumor, lung cancer, prostate cancer, pancreatic cancer, etc., may lead to high neutrophil ratio and need to be clearly diagnosed by tissue biopsy. These tumors are mainly treated by surgery, radiotherapy, chemotherapy and targeted therapy, etc.; 4. Hematological system diseases: such as true erythrocytosis, acute hemolytic anemia, recovery period of megaloblastic anemia treatment, etc., in which leukocytes and neutrophils can have a certain degree of increase, so the neutrophil ratio will be high, and the type of disease needs to be clarified by bone marrow examination, and the above hematological system diseases are mainly Perform medication; 5. Poisoning: lead poisoning, mercury poisoning, benzene poisoning, sleeping pill poisoning, snake venom poisoning, etc., can also appear neutrophilic, thus leading to high neutrophil ratio, which can be diagnosed by corresponding toxicological analysis or blood test, and patients with poisoning are mainly treated with medication, and those with acute oral poisoning can be treated with emetic gastric lavage, etc. Therefore, it is recommended that patients undergo further testing for related diseases if necessary, and then consult with the attending physician together with the results of other tests in order to clarify the type of disease and receive treatment in a timely manner.
