People who have their blood pressure measured as systolic over 130 and/or diastolic over 85 should be diagnosed with elevated blood pressure.

At initial presentation, patients showing features of a hypertensive urgency or emergency (Supplemental Table S3) should be diagnosed as hypertensive and require immediate management (Grade D). In all other patients, at least 2 more readings should be taken during the same visit. If using a non-AOBP measurement, the first reading should be discarded and the latter readings averaged. If using AOBP, the BP calculated and displayed by the device should be used.
If the visit 1 mean non-AOBP or AOBP SBP is 180mm Hg and/or DBP is 110 mm Hg then hypertension is diagnosed (Grade D).
If the out-of-office measurement, although preferred, is not performed after visit 1, then patients can be diagnosed as hypertensive using serial office BP measurement visits if any of the following conditions are met:
i. At visit 2, mean office BP measurement (averaged across all visits) is >= 140 mm Hg systolic and/or >= 90 mm Hg diastolic in patients with macrovascular target organ damage, diabetes mellitus, or chronic kidney disease (glomerular filtration rate < 60 mL/min/1.73 m2);
ii. At visit 3, mean office BP measurement (averaged across all visits) is >= 160 mm Hg systolic or >= 100mm Hg diastolic;
iii. At visit 5, mean office BP measurement (averaged across all visits) is >= 140 mm Hg systolic or >= 90 mmHg diastolic.
