At-home blood pressure monitors make it convenient for people to check their readings, but many of them still want assurance that the numbers are accurate for health reasons. Differences between readings at home and at the doctor's clinic may reveal that something is wrong with an at-home monitor. Hence, if you have been checking up on your blood pressure at home, it's more than likely you've gotten skewed results.

A study published in the American Journal of Hypertension, in 2017, suggests that 70 percent at-home blood pressure monitors are wrong and that inaccuracy could have serious health consequences. City experts advise you to regularly visit the doctor to get accurate readings, and not to solely rely on at-home blood pressure monitor.
