If the high neutrophil ratio is caused by physiological factors such as strenuous exercise, it can be observed and treated until it recovers on its own, while if it is caused by pathologic factors such as infection, it should be treated with anti-infective treatment. Physiological causes of high neutrophil ratio, such as late pregnancy or childbirth, after strenuous exercise, shower, high temperature, etc., can cause a temporary increase in neutrophil ratio, but pathological elevation can be seen in acute infections, hemorrhage, leukemia, and severe tissue injury. 1. If the elevation is caused by physiological reasons, the value will be restored after stopping the current cause of elevation, but if it is caused by pathological reasons, we need to find the cause of the disease and choose the appropriate treatment. 2. Infections should be treated promptly with anti-infection (levofloxacin), and acute hemorrhage should be stopped promptly with blood transfusion. When leukemia to find a specific type of targeted treatment, such as acute myeloid leukemia to be cytarabine, erythromycin and other drugs such as chemotherapy. If the neutrophil ratio is high, you should go to the hospital in time to complete the relevant examinations, and under the guidance of a professional physician to find out the reasons for the increase in neutrophils and receive targeted treatment.
