Increased neutrophil counts are usually suspected as a result of bacterial infections or abnormalities in the bone marrow hematopoietic system, and require antibiotic treatment or treatment for bone marrow abnormalities. 1. Bacterial infections can cause an increase in neutrophil count. Neutrophils have phagocytosis, which can kill invading bacteria, so neutrophils are increased by routine blood tests, and the clinical symptoms are often upper respiratory tract infections or fever, pain, and so on. Antibiotics are often used for treatment (such as amoxicillin, cephalosporins, etc.). 2. Bone marrow hematopoietic abnormalities can lead to increased neutrophils, such as acute granulocytic leukemia. The function of the white blood cells that cause the increase is abnormal, and there is often no defense resistance. Chemotherapy is often needed (hypertriglyceride, cytarabine, etc.), and antibiotic treatment (e.g., cephalosporins, etc.) is needed at the same time if there is an infection. The use of the above drugs needs to be under the guidance of a specialized doctor. If any of the above situations occurs, please consult a doctor for reasonable and standardized diagnosis and treatment in a timely manner.
