If the visit 1 office BP measurement is high-normal (thresholds outlined in section I, Recommendation 3) annual follow-up is recommended.
If the visit 1 mean non-AOBP or AOBP SBP is 180mmHg and/or DBP is 110mmHg then hypertension is diagnosed.
If at the last diagnostic visit the patient is not diagnosed as hypertensive and has no evidence of macrovascular target organ damage, the patient’s BP should be assessed at yearly intervals.

If hypertension is not diagnosed, measure the person's clinic blood pressure at least every 5 years subsequently, and consider measuring it more frequently if the person's clinic blood pressure is close to 140/90mmHg.
