High granulocytes need to be judged according to specific granulocyte types, such as neutrophils, eosinophils and basophils, etc. Commonly, high neutrophils usually suggest that the patient is suffering from traumatic hemorrhage, transient hypoxia, chronic nephritis and other conditions. 1. High neutrophil usually suggests that the patient is suffering from traumatic bleeding, transient hypoxia, etc. At the same time, such as chronic nephritis, granulocytic leukemia, diabetic ketoacidosis and other diseases, as well as advanced cancers, will lead to the patient’s body neutrophil index rise. 2. Elevated eosinophils usually indicate the presence of food allergies, bronchial asthma, intestinal parasitic infections, chronic leukemia and other conditions. 3. Elevated basophilic granulocytes are commonly seen in Hodgkin’s lymphoma, metastatic cancer, chronic granulocytic leukemia, and myelofibrosis. Leukocytes can be categorized into granular leukocytes and non-granular leukocytes according to their morphology, and granular leukocytes refer to granulocytes. Granulocytes contain special staining particles, and according to the different staining, they are also divided into neutrophils, eosinophils and basophils, and the most common granulocytes in the clinic are neutrophils. Therefore, the meaning of high granulocyte needs to be judged according to the actual elevated granulocyte type, and cannot be generalized. It is recommended that patients with elevated granulocytes undergo further examination to determine the specific type of granulocyte that is elevated, and then take appropriate therapeutic measures under the guidance of a physician according to the actual situation.
