Blood Pressure ScreeningSkip to the navigation
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
Your doctor can let you know how often you should get your blood pressure checked. It may depend on what your blood pressure is and your risk for heart disease. You can get your blood pressure checked during any routine medical visit.
The USPSTF makes these recommendations about how often to check your blood pressure:footnote 1
- Get your blood pressure checked every year if any one of the following is true:
- You're age 40 or older.
- You're African-American.
- You're overweight or obese.
- The top number of your blood pressure is 130 to 139, or the bottom number is 85 to 89, or both.
- You can get your blood pressure checked every 3 to 5 years if all of the following are true:
- You're age 18 to 39.
- And the top number of your blood pressure is lower than 130, and the bottom number is lower than 85.
- And you're not African-American, overweight, or obese.
Making sure that blood pressure is actually high
After measuring your blood pressure, your doctor may ask you to test it again when you are home.footnote 1 This is because your blood pressure can change throughout the day. And sometimes blood pressure is high only because you are seeing a doctor. This is called white-coat hypertension. To diagnose high blood pressure, your doctor needs to know if your blood pressure is high throughout the day.
So your doctor may ask you to monitor your blood pressure at home to make sure that it actually is high. You may get an ambulatory blood pressure monitor or a home blood pressure monitor. These devices measure your blood pressure several times throughout the day.
Screening in children and teens
Children and teens typically have their blood pressure checked during routine well-child visits and checkups. Blood pressure checks typically start after age 3. After age 18, men and women can follow the adult screening guidelines.
