High platelet count: There are many causes for a high platelet count. Many times it is reactive--in response to another medical issue like an infection or having no spleen but there are many other causes. It can also be a problem with the bone marrow function. The cause should be evaluated by a physician.

A 45-year-old member asked:

What causes a high platelet count and hypothyroid?

No one thing: No one thing would cause both of the conditions listed. However, in women, hypothyroidism can cause long heavy periods, which, over time, could lead to iron deficiency. Too many platelets is a common finding in iron deficiency anemia, and so it could be indirectly related to the hypothyroidism. However, too many platelets can have other causes as well, so it's best to ask your own doc about this.

Hematology 28 years experience
Thrombocytosis: A high platelet count can be seen in many different conditions, both benign and malignant: iron deficiency anemia, following splenectomy and other types of surgery, in association with cancer, and as a result of a group of bone marrow disorders known as myeloproliferative neoplasms. It is very important that a high platelet count be evaluated promptly by a hematologist.

Error,prodctn,distru: A random low platelet count is often the result of the nature of the test. Platelets are frail & may clump in the specimen before the test is run so a falsely lowered count is found.Low production during illness or bone marrow failure usually shows up in several blood cells. Increased destruction by immune factors or loss with bleeding disorders are seen. Platelets only last a few days at best.
