If your blood count is above 500,000, your doctor will likely look for an underlying condition. In most cases, signs and symptoms of the underlying condition help guide the diagnosis. Your doctor may also:
•Check the level of iron in your blood
•Test for markers of inflammation
•Order genetic testing to help determine if you have a blood and bone marrow disorder
•Conduct a bone marrow aspiration and biopsy to collect and examine bone marrow tissue
If you have thrombocytosis, making healthy lifestyle choices can help reduce your risk of complications. These choices include:
•If you smoke or use other tobacco products, quit.
•Avoid secondhand smoke.
•Manage other health conditions you might have, including high blood pressure, high cholesterol and diabetes.
•Avoid over-the-counter pain medications, with the exception of acetaminophen (Tylenol, others). Keep in mind that some cold medications may also contain pain medications, so read the labels carefully and talk to your doctor before taking any over-the-counter pain medications.
•If you take blood-thinning medications to manage thrombocytosis, tell your doctor or dentist before having any procedures done. These medications can increase your risk of bleeding during the procedure.
