A too high platelet count is an abnormally high number of platelets in the peripheral blood. First of all, the specific cause of the abnormally high platelet count should be clarified. If the platelet count is reactively increased due to severe trauma, surgery or infection, the primary cause needs to be actively controlled, such as controlling infection, treating trauma, etc. At the same time, appropriate anti-platelet medication should be given, including aspirin, Bolivar and other drugs, with the aim of preventing the formation of blood clots. If the platelets are too high, caused by primary thrombocytosis, firstly, a blood cell separator can be applied to separate the excessive platelets from the peripheral blood to reduce the number of platelets, while taking drugs such as hydroxyurea for treatment, and also subcutaneous injection of interferon and other drugs for treatment, both of which can reduce the number of platelets. The platelets are too high, and different treatments should be given according to the specific condition.
