The normal range for mean platelet volume in adults is 7-11 fL, and if it is lower than 7 fL, the indicator is low. If the average platelet volume is 8.4, it is within the normal range and should not affect the body much.
Mean platelet volume refers to the average volume of platelets in the peripheral blood, and testing platelets helps in the diagnosis of bleeding disorders. Clinically, low mean platelet volume is mostly caused by low hematopoietic function of bone marrow, most commonly aplastic anemia.
In addition, patients with malignant tumors may also have low mean platelet volume after chemotherapy, as the hematopoietic stem cells are damaged by the chemotherapeutic drugs, resulting in bone marrow suppression. When the bone marrow suppression is relieved, the low mean platelet volume will gradually recover until normal.
If there is a low mean platelet volume, it is important to consult a doctor in time to avoid the occurrence of adverse conditions.
