The standard way to test for hypertension is with an inflatable cuff that goes around your arm. It is easy to use, and you can get your blood pressure tested easily at a range of places. You can ask your doctor to test your blood pressure, but you can also test it at some pharmacies, health care centers or at the hospital.
You can also order a home testing kit so that you can check your blood pressure at home. But not all of them are accurate. If you do buy your own blood pressure monitor to use at home, ask your doctor about a reliable one.
