White blood cell types such as acute leukemia, chronic granulocytic leukemia, chronic lymphocytic leukemia, etc., may have high white blood cell counts, low white blood cell counts, or normal white blood cell counts. Whether the white blood cells are high or low cannot be generalized and should be judged in the light of the actual situation. 1. Acute leukemia: Most patients with acute leukemia will have increased white blood cells, while a few may have decreased white blood cells. In the blood smear, there are varying numbers of primitive and naïve cells, and some patients may have thrombocytopenia. 2. Chronic granulocytic leukemia: patients with chronic granulocytic leukemia may have a significant increase in white blood cells, as well as an increase in eosinophils and basophils. 3. Chronic lymphocytic leukemia: patients with chronic lymphocytic leukemia may have a continuous increase in lymphocytes, accompanied by elevated white blood cells, thrombocytopenia or anemia. It is suggested that patients with leukemia can undergo relevant examinations to clarify the situation of white blood cells, and specific diagnosis and treatment should be carried out under the guidance of physicians.
