A high platelet count and platelet pressure product indicates that the number of platelets in the peripheral blood exceeds the normal range before an increase in platelet count and platelet pressure product occurs. In clinical practice, there are two causes of increased platelet count and platelet pressure: first, reactive platelet count, which is the increase in platelet count caused by other causes, most commonly acute infections, such as acute appendicitis, acute tonsillitis, acute gastroenteritis, acute cholecystitis, etc., can cause an increase in platelet count, and certain major surgeries, bleeding, trauma, hemolysis, etc., may induce an The platelet count may increase, thus causing a high platelet pressure. Secondly, primary thrombocytosis is an abnormal increase in the number of platelets caused by bone marrow diseases, the most common in clinical practice is primary thrombocytosis, true erythropoietic disease and other myeloproliferative diseases, the number of platelets often appears abnormally high, platelet pressure will also appear significantly higher.
