It's easy to walk into a pharmacy and find a simple blood pressure testing device, but these results are often not accurate for the average person since walking around and doing errands during the day and then measuring blood pressure in a store can often make for inaccurate results. Many doctors are suggesting that home blood pressure monitors be used by patients with high blood pressure to eliminate the prospect of a false reading since a person can take their pressure when they wake up which might be the most accurate time to measure it on a regular basis.
