<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing severe headaches and blurred vision lately. I went to see an ophthalmologist who referred me to you, and he mentioned that it might be malignant hypertension.  <response>: In that case, we need to perform a series of medical tests to confirm the diagnosis. Your first test will be a Hematologic test or a blood test, which will tell us about your blood disorders, such as anemia or abnormal platelet counts. We will also need to conduct a Complete Blood Count CBC to measure your white and red blood cell counts.Patient: Alright, I understand. What about the other tests?
