A large number of studies have been done in the general population comparing ambulatory blood pressure monitoring (ABPM) to casual, office based and home measures of blood pressure (BP). The results have clearly demonstrated that ABPM gives a more accurate representation of BP and arguably should be used as part of routine patient care. ABPM has been shown to reveal patients both with white-coat and with masked HTN, nocturnal HTN and lack of nocturnal dipping. Ambulatory BP measures afford us a non-invasive, highly accurate way to evaluate and treat kidney transplant recipients.
