How is Essential Thrombocythemia diagnosed?
How Essential Thrombocythemia is diagnosed: tests, specialists and the diagnostic journey, told by patients and reviewed against medical sources.
If your blood count is above 450,000 platelets per microliter of blood, your doctor will look for an underlying condition. He or she will rule out all other causes of high platelet counts to confirm a diagnosis of essential thrombocythemia. Blood tests may include:
Complete blood count. This test determines the number of platelets in your blood.
Blood smear. A small amount of your blood is examined under a microscope to view the size and activity of your platelets.
Genetic testing. Special tests can determine whether you have chromosomal abnormalities that can cause a high platelet count and whether you have a JAK2, CALR or MPL gene mutation.
Other blood tests. Your doctor may check the level of iron in your blood or test for markers of inflammation.
Your doctor may also suggest two bone marrow tests:
Bone marrow aspiration. Your doctor extracts a small amount of your liquid bone marrow through a needle. The sample is examined under a microscope for abnormal cells.
Bone marrow biopsy. Your doctor takes a sample of solid bone marrow tissue through a needle. The sample is examined under a microscope to determine whether your bone marrow has a higher than normal number of the large cells that make platelets (megakaryocytes).
Blood Tests
Blood tests can exclude other causes of a high platelet count (“reactive”). This often includes tests for iron deficiency and indicators of inflammation as well as other mimicking blood diseases.
Bone Marrow Biopsy
A bone marrow biopsy may be done to look for classical signs of ET (e.g., an increase in platelet precursors) or to exclude an early phase of MF.
Gene Mutation Analysis of Blood Cells
Physicians may also test for gene mutations like JAK2 (occurring in approximately 50% of cases), CALR (occurring in 23.5% of cases) or MPL (occurring in up to 5% of cases).

Through blood tests and bone marrow biopsy

i had a bit of discomfort in my upper abdomen which is obviously a swollen spleen. i wend for a general check up and turned out i have high platelets!
my head gets dizzy and heavy/light a lot of the time and i get pains in my legs
