Ambulatory Blood Pressure Monitoring (ABPM) is a diagnostic test that measures blood pressure at regular intervals over a 24-hour period while the patient carries out their normal daily routine, including during sleep. It provides a detailed profile of blood pressure behaviour across a full day and night cycle, offering insights beyond what can be obtained from isolated clinic readings.

ABPM is particularly useful for identifying white coat hypertension, masked hypertension, and evaluating blood pressure variability. It plays a key role in confirming a diagnosis of hypertension, assessing treatment efficacy, and guiding personalised cardiovascular risk management.
