A mean platelet volume of 7.2 is within the normal range and is not serious. The normal range of mean platelet volume is 7fL~11fL, generally more than 11fL belongs to the high mean platelet volume. Mean platelet volume refers to the average volume of individual platelets, simple slight high generally does not have clinical significance, indicating that the bone marrow hematopoietic function is better, generally do not need special treatment. If the mean platelet volume is obviously high or accompanied by obvious coagulation abnormalities, it may suggest disease-related. Significantly high mean platelet volume is most commonly seen in immune thrombocytopenic purpura, myelodysplastic syndromes, and acute leukemia in remission. Decreased mean platelet volume is common in people with poor bone marrow hematopoiesis or decreased platelet production, and can also be seen in patients with leukemia. In addition, if the mean platelet volume decreases consistently with the platelet count, it is one of the indicators of bone marrow hematopoietic failure. If the average platelet volume is abnormal, it is recommended to go to the regular hospital to improve the relevant examination, the doctor combined with the patient’s examination results and clinical manifestations to make professional judgment, treatment for the disease, so as to improve the average platelet volume, the patient should not be self-diagnosis and treatment in order to avoid delaying the condition.
