Allergic reactions, physical trauma and major surgery can cause a temporary elevation in platelet count, explains MedlinePlus. Additional causes of a high platelet count include polycythemia vera, primary thrombocythemia, chronic myelogenous leukemia and certain medications.


What causes high platelet count? Thrombocytosis is the medical term used to describe the display of elevated platelet count. The higher end of the normal platelet count range may vary from lab to lab, but is typically around 350 to 450 × 10 9 / L. . Doctors can detect thrombocytosis during routine blood tests.


The treatment for elevated platelet count will depend on the underlying cause. Drugs that reduce the platelet count, for example hydroxy carbamide and busulfan can be used. However, if the elevated platelet count is accompanied by an increase in the viscosity, then blood thinners that reduce the viscosity of blood (aspirin, warfarin) can be used.


What Are the Causes of Elevated Platelet Count?. Platelets are also called thrombocytes. They are small fragments of large bone marrow cells (megakaryocytes) that clump together to assist in the clotting of blood. Thrombocytes are smaller than red and white blood cells. A normal platelet count is about 150,000 to 400,000 per milliliter of blood.


Answer. A high platelet count is called thrombocytosis. By definition, any platelet count over 450 thousand is considered to be high. However, only levels above 750 thousand are routinely worked up unless other concerning symptoms accompany the thrombocytosis.


According to the Mayo Clinic, elevated platelet count, also known as thrombocytosis, is a disorder in which excess platelets are produced, leading to abnormal blood clotting or bleeding. Platelets are small fragments of the red blood cells produced in bone marrow.


In general, a platelet count more than 450,000 cells per microliter is considered elevated; this is known as thrombocytosis. There are numerous causes of thrombocytosis and fortunately, the majority are benign and transient. Let's will review some of the most common causes.


High MPV is due to the destruction of platelets. Some of the causes of high MPV are mentioned above. You need to be aware of these causes, and once you notice any signs, it is highly advisable to go to your doctor for a series of tests immediately.


Even though the platelet count is elevated for a short time (or even indefinitely after splenectomy), secondary thrombocytosis does not typically lead to abnormal blood clotting. Primary thrombocytosis, or essential thrombocythemia, can cause serious bleeding or clotting complications.


An elevated platelet count is known as thrombocytosis. The laboratory where the test was performed will be able to tell whether a platelet count of 420,000 represents an elevated value for this laboratory. An elevated platelet count can be observed in people without significant medical problems.
