The U.S. Preventive Services Task Force recommends screening for adults 18 and older for high blood pressure.¹

Tests and programs for high blood pressure vary widely in reliability. Results from automated blood pressure testing, such as you might do at a grocery store or pharmacy, may not be accurate. Any high blood pressure measurement discovered during a blood pressure screening program needs to be confirmed by a doctor or another health professional.

Rechecking blood pressure

The Seventh Joint National Committee (JNC 7) on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends:²

• Healthy adults with normal blood pressure (119/79 mm Hg or below) should have their blood pressure checked at least every 1 to 2 years. This can be done during any routine medical visit.
• Adults who are prehypertensive (120–139 and/or 80–89 mm Hg) should have their blood pressure checked as often as recommended by their doctor, or at least yearly. This can be done during any routine medical visit.
• Adults with other risk factors for heart or blood vessel disease or evidence of disease caused by high blood pressure need to have their blood pressure checked more often.
