A high platelet level may be detected in a routine blood test known as a complete blood count. It's important to determine whether it's reactive thrombocytosis or essential thrombocythemia to choose the best treatment options.
Thrombocytosis involves having an elevated level of platelets in your blood. Too many platelets can cause a stroke, heart attack or clot in your blood vessels.
Your platelet count may be high for only a short time. This can be caused by: Recovery from serious blood loss; Recovery from a very low platelet count caused by drinking too much alcohol and having low levels of vitamin B12 or folate; Acute (short-term) infection or inflammation
Thrombocytosis, or a high platelet count, is diagnosed when platelet levels are greater than 450,000 platelets per microliter of blood. It's not always obvious when to worry about a high platelet count. Many times, a high platelet count isn't serious and may not cause symptoms.
Inflammatory conditions like autoimmune diseases, cancer or trauma, as well as certain infections and iron deficiency, are common causes of a high platelet count. Treatment is directed at the stimulus, and the platelet count returns to normal once resolved.
Thrombocytosis refers to an increased platelet count which, in this review, is >450,000/microL (>450 x 10 9 /L). This topic discusses our approach to the adult or child with unexplained thrombocytosis. Clinical manifestations and diagnosis of specific causes of thrombocytosis are discussed separately.
Have a very high platelet count. Your doctor might prescribe platelet-lowering drugs such as hydroxyurea (Droxia, Hydrea), anagrelide (Agrylin) or interferon alfa (Intron A). In emergencies, platelets can be filtered from your blood with a machine. This procedure is called plateletpheresis.
A platelet count (PLT) is a quick, common test that counts the number of platelets in your blood. It’s important not to panic if you see your platelet counts flagged as “high” or “low” on your test results. A range of conditions and even medications — many of them harmless — can cause abnormal platelet levels.
High platelets is a condition in which the blood contains more platelets than usual. Platelets, or thrombocytes, are small blood cell fragments that assist in blood clotting and help stop bleeding. Clinicians can identify a high platelet count through routine blood tests.
When there are too many platelets in the blood, this is referred to as thrombocytosis. A normal platelet count is 150,000 to 450,000 platelets per microliter (mcL) of blood. A diagnosis of thrombocytosis is made when platelets are higher than 450,000 per mcL. This article discusses the types, symptoms, causes, and diagnosis of thrombocytosis.
