High platelets are called thrombocytosis or thrombocythemia, depending on the underlying cause.
Here's a more detailed explanation:
-
Thrombocytosis: This term refers to a high platelet count that is caused by another underlying condition, such as an infection, inflammation, iron deficiency, surgery, or certain medications. It is also known as secondary thrombocytosis.
-
Thrombocythemia: This term refers to a high platelet count that is not caused by another underlying condition. It is a myeloproliferative neoplasm, meaning it's a blood cancer where the bone marrow produces too many platelets. Thrombocythemia is sometimes referred to as primary or essential thrombocythemia.
In summary, while both terms indicate an elevated platelet count, understanding the distinction between them is crucial for proper diagnosis and treatment. Thrombocytosis is a response to another issue, while thrombocythemia is a condition in itself.
