Ambulatory Blood Pressure Monitoring
A wearable device that measures your blood pressure at regular intervals over 24 hours to provide a highly accurate diagnosis.
Ambulatory blood pressure monitoring (ABPM) is a 24-hour automated blood pressure recording performed during normal daily activity and sleep. It is the gold-standard investigation for accurate hypertension diagnosis, overcoming the limitations of single clinic readings.
Book This Evaluation
A portable monitor automatically measures blood pressure throughout the day and night to uncover hidden patterns.
What It Detects
- White coat hypertension — elevated clinic readings with normal ambulatory values
- Masked hypertension — normal clinic readings with elevated ambulatory pressure
- Nocturnal hypertension — elevated night-time blood pressure
- Non-dipping and reverse dipping patterns — abnormal sleep-related blood pressure behaviour
- Masked nocturnal hypertension — isolated elevated night-time pressure despite normal daytime readings
How It's Performed
A blood pressure cuff is fitted to the upper arm and connected to a portable device worn at the waist. The device inflates automatically every 20–30 minutes during waking hours and every 30–60 minutes during sleep. Patients maintain a brief activity diary and must keep the device dry.
What Results Mean
- Daytime average ≥135/85 mmHg — hypertension
- Night-time average ≥120/70 mmHg — nocturnal hypertension
- 24-hour average ≥130/80 mmHg — sustained hypertension
- Results guide treatment decisions and medication timing (morning vs. evening dosing)
Who Should Get It
- Elevated or borderline clinic blood pressure readings
- Suspected white coat effect
- Normal clinic readings but evidence of target organ damage
- High-risk patients: diabetes, chronic kidney disease, sleep apnoea, prior stroke
- Monitoring of treated hypertension
