The platelet pressure product mainly reflects the platelet count, with a normal value of 0.11%-0.23%. The normal value varies with the laboratory equipment, relevant reagents and test methods used in each region, and should be compared with the standard value provided by the local laboratory. A high platelet pressure product indicates a high platelet count or a high average platelet volume, mainly in diseases such as post-splenectomy, leukemia in remission, and myelodysplastic syndrome; a low platelet pressure product is considered to be a decrease in platelet count or a decrease in average platelet volume, seen in hypersplenism, etc.
