Results

Blood pressure for adults age 18 and older (mm Hg)2
Normal:

Systolic

119 or below

Diastolic

79 or below

Prehypertension:

Systolic

120 to 139

Diastolic

80 to 89

Hypertension:

Systolic

140 or above

Diastolic

90 or above

Blood pressure readings of less than 90/60 mm Hg are normal as long as you feel well. In general, the lower your blood pressure, the better. But if you have low blood pressure and feel lightheaded, faint, or like you may vomit, talk to your doctor.

What Affects the Test

Blood pressure normally goes up and down from day to day and even from moment to moment. Blood pressure tends to be higher in the morning and lower at night. Stress, smoking, eating, exercise, cold, pain, noise, medicines, and even talking can affect it. A single high reading does not mean you have high blood pressure, and a single normal reading does not necessarily mean you do not have high blood pressure. The average of several repeated measurements throughout the day is more accurate than a single reading.

Your blood pressure may only be high when you go to your doctor's office. This is called white-coat (or office) hypertension and may be caused by stress about seeing your doctor. When you regularly check your blood pressure at home, you may find that your blood pressure is lower when you are not at the doctor's office.

What To Think About

Do not adjust your blood pressure medicines based on home blood pressure readings unless your doctor tells you to.
