24-Hour Ambulatory Blood Pressure Monitoring (ABPM) Service

What is 24-Hour ABPM?

24-hour Ambulatory Blood Pressure Monitoring (ABPM) is a test that measures your blood pressure at regular intervals over a full day and night, while you go about your normal routine. It gives your doctor a more accurate picture of how your blood pressure changes throughout the day and night.

Why is it recommended?

Your GP may suggest ABPM if:

• Your clinic blood pressure readings have been high or variable.

• They want to confirm a diagnosis of high blood pressure (hypertension).

• They want to assess how well your blood pressure is controlled with treatment.

• You experience symptoms such as dizziness or headaches that may be related to blood pressure.

What does the test involve?

• A cuff will be placed on your upper arm and connected to a small monitor worn on a belt or shoulder strap.

• The device will automatically inflate the cuff and record your blood pressure every 20–30 minutes during the day and every 30–60 minutes at night.

• You’ll wear the monitor for up to 24 hours, then return it to the practice. Our clinician will sugget you how long you need to have the machine on.

How should I prepare?

• Wear loose-fitting clothing so the cuff can be comfortably worn on your upper arm.

• Avoid strenuous exercise, caffeine, or alcohol on the day of the test unless advised otherwise.

• Try to go about your normal day, but avoid showering or bathing while wearing the monitor (as it is not waterproof).

During the Monitoring Period

• Try to keep your arm still and relaxed during each reading. You may feel a gentle squeeze from the cuff.

• Keep a diary of your activities will be helpful if you can, including: Times of meals, Exercise, Stressful events, Sleep and wake times, Any symptoms (e.g. dizziness, headache)

Returning the Monitor

• Please return the monitor at the time advised by your GP practice (usually the following day). If you are unable to return it yourself, a reliable family member may do so on your behalf. Ideally, the monitor should be returned to the practice within 30 minutes of being removed at home.

• A healthcare assistant will remove the device.

What happens next?

• The data will be downloaded and reviewed by your GP.

• You may be contacted to discuss the results and next steps.

Important Notes

• Let the practice know if you have any allergies to latex or if you have any concerns about wearing the monitor.

• If the cuff feels uncomfortable or causes pain, contact the practice.

If you have any questions or need to reschedule your appointment, please contact our reception team.
