Multiple Blood Pressure Readings Should Be Taken

One blood pressure reading is not enough to get an accurate measurement. While the specifics of how many readings are necessary can change based on many factors, the essential need for multiple measurements does not.

To ensure an accurate reading, your doctor should be checking your blood pressure over time, and watching the how the values change between office visits. More than this, though, he should actually be taking your blood pressure more than once during each office visit.

Because things like temperature and stress can change blood pressure, more than one reading in a single office visit allows the ability to correct for these variations. For example, your blood pressure is often higher at the beginning of an office visit than at the end. Taking a reading at both the beginning and the end gives a more accurate average reading.

Your doctor should be checking your blood pressure:

  • In both arms, not just one
  • At both the beginning and the end of your appointment
