How is thrombocytosis diagnosed?
Finding the underlying condition (such as iron deficiency anemia, cancer, or infection) can aid in the diagnosis and management of thrombocytosis. If no secondary cause is identified, the patient is presumed to have ET.
A blood test for a specific gene, called JAK2, can diagnose thrombocytosis. However, it is positive in only about 50% of the cases. Other gene mutations are also tested, but are only positive in a low percentage of patients.
The patient may have bone marrow removed and examined to help confirm the diagnosis.
