White blood cells are white blood cells, and a high white blood cell count is an elevated white blood cell count. The normal range of white blood cell count is: adults (4-10)*10^9/L, children (5-12)*10^9/L, and newborns (15-20)*10^9/L. Elevated white blood cell count is >10*10^9/L. Elevated white blood cell counts are categorized as reactive agranulocytosis and abnormally proliferative agranulocytosis. Reactive agranulocytosis is seen in infections, poisoning, tissue trauma, malignant tumors, acute hemorrhage, and rheumatoid arthritis. Abnormal proliferative agranulocytosis is seen in acute and chronic granulocytic leukemia. When high white blood cells should go to the hospital in time to find the cause of the disease, early detection, early treatment.
