A platelet pressure product of 0.350 is the product of the mean platelet volume and platelet count of 0.350. The magnitude of platelet pressure product is related to the mean platelet volume and the number of platelets. Its normal range is about 0.110% to 0.230%. Platelet pressure product of 0.350 indicates a significant increase in platelet pressure product, which may be due to an increase in the mean platelet volume or an increase in platelet count. 1. Increased mean platelet volume can be seen in diseases such as primary thrombocythemia and megaloblastic anemia. 2. Increased platelet count, which can be seen in myelodysplastic syndrome, acute blood loss, acute hemolysis and other diseases. There may also be other reasons, need to be integrated platelet other indicators for judgment. When the platelet count is 0.350, the patient should consult the doctor for further examination and receive appropriate treatment after clarifying the cause of the disease.
