Diagnostic algorithm for the diagnosis of hypertension

• mean automated office BP (AOBP) or office BP measurement (OBPM) sBP is ≥180 mmHg or dBP is ≥110 mmHg = HTN
• if diabetic, OBPM ≥130/80 mmHg for ≥3 measurements on different days = probable HTN, rule out white coat HTN
• if not diabetic and AOBP ≥135/85 mmHg or OBPM ≥140/90 mmHg, rule out white coat HTN
• ambulatory BP monitoring (ABPM) daytime mean ≥135/85 mmHg OR ABPM 24 hr mean ≥130/80 mmHg = HTN
• Home BP monitoring (HBPM) series mean ≥125/85 mmHg = HTN
