What is 24 hour ambulatory blood pressure?

24-hour ambulatory blood pressure is a test that continuously measures and records changes in an individual's blood pressure over a 24-hour period.

24-hour ambulatory blood pressure is a noninvasive test that can help doctors assess a person's blood pressure status. By continuously monitoring blood pressure, doctors can obtain blood pressure information at different times of the day, including daytime, nighttime and sleep periods. This can help determine whether abnormal blood pressure is present during the day, insufficient blood pressure drop during the night, and even detect fluctuations in blood pressure to more accurately assess the severity and risk of hypertension.

Some people with abnormal blood pressure can be further diagnosed by medical tests such as blood tests and CT tests to prevent delays in treatment.
