Decreased white blood cell count refers to a decrease in the number of white blood cells, which are divided into five types in the blood, including eosinophils, neutrophils, basophils, lymphocytes, and monocytes. Among them, the reduction of classified cells will affect the number of white blood cells.
1. Patients suffering from aplastic anemia, granulocyte deficiency, hypersplenism, or some physical or chemical injuries have low neutrophil counts due to lack or destruction of neutrophils, which can affect the total number of white blood cells.
2. In addition, immunodeficiency diseases, as well as the application of chemicals (cytarabine) and adrenocorticotropic hormones in clinical practice, and exposure to radiation may cause low lymphocyte counts, which may also affect the total number of white blood cells.
There are many reasons for the decline in white blood cell count, and there are limitations in determining the clinical significance of white blood cell count alone. Further examination should be conducted, combined with relevant information to make a comprehensive judgment, clarify the cause, and timely treatment under the guidance of physicians.
