Mean platelet volume is the average of platelet volume. If it is only slightly low and there are no other symptoms or abnormal test results, it is usually a physiological cause and there is no need to worry too much. If the average platelet volume is significantly low, it is often related to leukemia, aplastic anemia or chemotherapy, but other tests are needed to clarify the cause and treatment. 1, leukemia: most leukemia patients will have a low average platelet volume, and in severe cases, it is also accompanied by hypersplenism, leukemia patients can use chemotherapy to destroy the proliferating leukemia blood cells inside the bone marrow, thus improving the average Aplastic anemia: Patients with aplastic anemia have reduced hematopoietic stem cells due to the failure of bone marrow hematopoietic function, resulting in low average platelet volume. The average platelet volume may also be low due to hematopoietic stem cell suppression and bone marrow suppression.
