<human>: Is there a way to tell if a person has high blood pressure?
<bot>: Yes, there are several ways to determine whether someone has high blood pressure. One of the most common methods is to take their blood pressure and compare it with normal values for that individual's age, sex, and height. Other tests may be done such as measuring the thickness of the walls of the arteries, looking at the heart rate or using an ultrasound machine to measure the flow of blood in the body.
