Preparing for your appointment
By Mayo Clinic staffIf your doctor thinks you have secondary hypertension, you'll likely need an appointment to confirm that you have the condition. Your doctor may order blood tests, urinalysis, an ultrasound or an electrocardiogram as part of your appointment.
Your doctor should tell you if there are any special instructions to follow before your tests. You may have to fast for nine to 12 hours if you're having a blood test so that your doctor gets the most accurate results.
Your doctor may also ask about your family history of high blood pressure. If you don't have a family history of high blood pressure, it's possible your blood pressure could be caused by another medical condition.
