Accuracy Testing of Validated and Non-validated Home BP Devices Sold on the Online Market.
This study is looking into how accurate blood pressure machines sold online are. Many people with high blood pressure (hypertension) use these devices at home, but it's not always clear if they give reliable readings. Researchers will compare readings from various home blood pressure monitors – some that have been officially approved and some that haven't – with a more detailed test called 24-hour ambulatory blood pressure monitoring (awake ABPM). This special test measures your blood pressure frequently throughout the day while you go about your normal activities. The goal is to find out if the home devices match the results from the accurate 24-hour monitoring. This information will help ensure people are using trustworthy devices to manage their health.
At a glance
What is this study about?
You might be familiar with high blood pressure, also known as hypertension. It's a common condition where your blood pushes too hard against the walls of your arteries. If not managed, it can lead to serious health problems like heart disease or stroke. Many people with high blood pressure are encouraged to check their readings at home using a blood pressure monitor bought online or from a shop.
This study wants to find out if these home blood pressure monitors, especially those bought online, actually give correct readings. There are lots of different home monitors available, and some have been officially checked and approved for accuracy (we call these 'validated'), while others haven't. The researchers want to compare both types of devices to a very reliable method of checking blood pressure.
To do this, they will use something called 24-hour ambulatory blood pressure monitoring, or 'awake ABPM'. This involves wearing a small device that automatically takes your blood pressure every 20-30 minutes during the day while you're awake and doing your usual activities. By comparing the home monitor readings to these detailed and accurate ABPM results, the study aims to show which home devices are trustworthy and help people make better choices when buying them.
Key takeaways
- The study checks if home blood pressure monitors from online stores are accurate.
- It compares them to a highly accurate 24-hour blood pressure test.
- Both officially approved ('validated') and unapproved ('non-validated') devices are being tested.
- The goal is to help people with high blood pressure choose reliable home monitors.
- Participants must be adults already having a 24-hour blood pressure test.
Who may be eligible?
This study is looking for adult volunteers, aged 18 or older, who are already scheduled to have a special 24-hour blood pressure test called an ABPM. This group of people is ideal because they will already be using the accurate monitoring method that the study wants to compare home devices against.
However, there are some reasons why you might not be able to join. For example, if your upper arm is much smaller than 22cm or larger than 42cm, the blood pressure cuff used in the study might not fit correctly. People who work night shifts, have a specific heart condition called permanent atrial fibrillation, or a serious heart valve problem called aortic stenosis, won't be able to take part. Also, if there's a medical reason why blood pressure can't be measured on your non-dominant arm (the arm you don't write with), you won't be eligible.
Finally, if you are currently pregnant or unable to fully understand and agree to take part, you wouldn't be able to join this study. The researchers need to make sure everyone involved is safe and understands what they are agreeing to.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you scheduled to have a 24-hour blood pressure monitoring (ABPM) test soon?
- Is your upper arm size between 22 cm and 42 cm?
- Are you not currently pregnant?
- Do you not work night shifts?
- Do you not have permanent atrial fibrillation or severe aortic stenosis?

Common questions
What is hypertension?
Hypertension is the medical term for high blood pressure. It means your blood is pushing too hard against your artery walls, which can lead to health problems if not controlled.
What is an 'awake ABPM'?
ABPM stands for Ambulatory Blood Pressure Monitoring. An 'awake ABPM' is a special test where you wear a small device for a day that automatically measures your blood pressure every 20-30 minutes while you are awake and going about your daily life. It gives a very accurate picture of your blood pressure over time.
Why are some home blood pressure devices called 'validated' and others 'non-validated'?
A 'validated' device has been officially tested and shown to give accurate readings compared to medical standards. A 'non-validated' device hasn't gone through these official checks, so its accuracy isn't guaranteed.
Why is it important to know if online blood pressure monitors are accurate?
Many people with high blood pressure use these monitors at home. If the readings aren't accurate, it could mean their blood pressure isn't being managed correctly, which could be risky for their health.
