It does not matter if the average platelet volume is a little low. The average platelet volume is the average of all platelets in the blood, and the low platelet volume is mostly seen in physiological changes, for example, after the occurrence of intracranial hemorrhage, gastrointestinal hemorrhage and other serious bleeding disorders, the bone marrow will reactively generate platelets to increase the number of platelets, which leads to the small platelet volume, which may lead to the average platelet volume is a little bit small. It may also be caused by pathological diseases, such as primary thrombocythemia and other myeloproliferative tumors, the patients of this disease, the bone marrow megakaryocyte proliferation is obviously active, the production of platelets increased significantly, there may also be a small volume of platelets, which leads to the average platelet volume is small. Patients need to consult the hematology department in time to clarify the specific cause of the disease and then treat the cause of the disease.
