Platelet volume distribution width, also known as platelet distribution width, refers to the dispersion of platelet size. If the platelet volume distribution width is low in routine blood tests, but other indicators are normal, it means that the platelet homogeneity is high and the morphology and volume are relatively consistent, so don’t worry too much and pay attention to review. If the platelet volume distribution width is low and other indicators are abnormal, it may be caused by diseases, such as aplastic anemia and acute leukemia. 1, aplastic anemia: in patients with aplastic anemia, the average volume of platelets can be reduced due to the reduction of bone marrow hematopoietic function in the body, resulting in a low platelet volume distribution width, while white blood cells, hemoglobin and platelets can be reduced. This may be accompanied by a decrease in white blood cells, hemoglobin, and platelets, i.e., trilineage reduction. Such patients can be treated with immunosuppressive therapy or hormonal hematopoietic therapy to improve accordingly; 2, acute leukemia: some acute leukemia patients after chemotherapy, there will be a period of myelosuppression, which will cause a decrease in platelets in the body, which will lead to low platelet volume distribution width, accompanied by a decrease in the absolute value of neutrophils, hemoglobin, can be used under the guidance of doctors Recombinant human platelet thrombopoietin can be used under the guidance of a doctor to improve the situation of low platelets in the body. For patients with low platelet volume distribution width, it is recommended to clarify the cause of the disease in conjunction with other test results, develop a treatment plan for the cause, communicate with the doctor more during treatment, and actively cooperate with the treatment.
