If the platelet volume is only slightly low and there are no other symptoms or abnormalities, it is generally not important; however, if it is severely low, it often indicates that there may be abnormalities such as hematopoietic failure, which is a more serious condition. Platelets are cells in the blood that are mainly involved in the clotting process. Platelet volume is also known as platelet volume, the normal range is 7~11fl, more than normal is the increase of platelet volume, and lower than normal is the decrease of platelet volume. 1. If the platelet volume only deviates from the normal range, and there are no uncomfortable symptoms, and no obvious abnormalities in other tests, it usually does not matter, and only needs to be observed and followed up. 2. However, if the platelet volume is obviously small, it is common in bone marrow hematopoietic failure diseases, such as aplastic anemia or some acute myeloid leukemia. Of course, some sepsis may also cause low platelet volume. These conditions are serious and require prompt medical attention. For example, acute myeloid leukemia is treated with cytarabine chemotherapy. If low platelet volume is accompanied by other manifestations, it is recommended to consult a doctor in time to identify the cause and treat the cause under the guidance of a physician.
