Blood pressure testing is important for most people, and this is why it's a routine part of most doctor's appointments. Some people need blood pressure testing quite often. Young adults (people 18 years old and older) should have a blood pressure test at least once every two to five years. Some young adults have an increased risk of high blood pressure, so these people may need a blood pressure test each year. Older adults (people 40 years old and older) may also need a blood pressure test each year. There are some other people who may need yearly testing. For example, people with chronic health conditions, like high blood pressure, low blood pressure, or heart disease, might need yearly testing. Some of these people may even need testing more often than that.
