The number of readings needed from ambulatory blood pressure monitoring to diagnose hypertension or determine adequacy of blood pressure control, is largely based on opinion and is not consistent among major guidelines. To address this issue empirically, Agarwal and Tu examined 24-hour ambulatory blood pressure data from 360 individuals who had chronic kidney disease and hypertension, and 38 healthy controls. Almost all were white males. They determined that 15 randomly selected or 40 serial recordings of systolic or diastolic blood pressure taken over a 24-hour period is sufficient to accurately evaluate blood pressure control.
