24 hour blood pressure monitoring is accurate.

24-hour blood pressure monitoring is generally more accurate.

24-hour blood pressure monitoring equipment usually uses ambulatory blood pressure monitoring technology, which can continuously monitor the patient's blood pressure and provide more comprehensive blood pressure information. Compared with traditional clinic blood pressure measurement, 24-hour blood pressure monitoring can capture more blood pressure data, including nighttime blood pressure, daytime blood pressure, activity and rest blood pressure, and the detection results are more accurate. However, the exact accuracy of 24-hour blood pressure monitoring depends on a number of factors, including the quality of the device itself, the patient's cooperation, and the accuracy of data interpretation.

Therefore, it is recommended that the device be worn correctly according to the doctor's requirements to ensure that the device is not disturbed by external factors.
