Ideal blood pressure is categorized as normal. Increased blood pressure may be categorized as elevated, stage 1 or stage 2 depending on the specific numbers. A diagnosis of high blood pressure is usually based on the average of two or more readings taken on separate visits.

Blood pressure categories include normal blood pressure, defined as a systolic pressure less than 120, and a diastolic pressure less than 80. Elevated blood pressure is defined as a systolic pressure 120 to 129, and a diastolic pressure less than 80.
