Leukocyte is a general term for a group of cells in the blood, mainly including monocytes, lymphocytes, and neutrophils. The normal value of white blood cells is (4-10) x 109/L, and anything above this range is called leukocytosis. A high white blood cell count does not necessarily mean that you have leukemia. High blood leukocytes are common in inflammatory infections, bleeding, poisoning, and severe burns. When they are particularly high, leukemia is certainly not excluded.

　　Generally speaking, the symptoms of leukemia are mainly anemia and some related symptoms such as: weakness, pallor, loss of appetite, weight loss and so on. Easy to bruise or bleed, such as: bleeding from the dental bed, nosebleed. Highly susceptible to infections, e.g., sore throat, bronchitis with headache, low-grade fever, sore mouth, and skin rashes. Enlarged lymph nodes, especially in the throat, armpits and groin. Feeling of discomfort under the left hypochondrium. In severe cases, there is a sudden onset of high fever, clouded consciousness, and inability to speak or move limbs. The diagnosis of leukemia requires further tests, such as bone marrow imaging, to make a definitive diagnosis. Leukemia is a malignant clonal disease of hematopoietic stem cells.

　　Therefore, high blood leukocyte count does not necessarily mean leukemia. If you suspect that you have the above symptoms of leukemia, it is best to go to the hospital for a comprehensive examination and a clear diagnosis of the disease in order to target the treatment. If the white blood cells are elevated due to inflammation, sensitive antimicrobial and anti-inflammatory drugs should be taken to actively treat the disease, and the white blood cells can be normalized after the inflammation is under control. Many physiological factors can cause an increase in the total number of white blood cells. For example: strenuous exercise; physical labor; prolonged exposure to cold air in winter; after a full meal, shower, there is often a slight increase in the number of white blood cells, but these causes of white blood cell elevation does not need to be treated.
