In-Clinic vs At-Home Blood Pressure

Understanding At-Home vs. In-Clinic BP Readings

Your blood pressure is typically lower at home.

It’s important to know that the blood pressure (BP) measurements you take at home may be different from the readings you have taken at a clinic. At-home measurements tend to be more accurate.

That’s because some people’s BP rises abnormally high at the doctor’s office due to stress. Other people may have lower-than-normal BP at the doctor’s office. Measuring and tracking your BP at home can give your doctor more reliable data on which to base your treatment.

The American Heart Association has different guidelines for what qualifies as Stage 1 or Stage 2 hypertension, depending on where the reading was taken (see below). When your doctor goes over your at-home measurements, he or she should take this difference into account.
