What is CGM accuracy? Have you wondered if Continuous Glucose Monitors (CGMs) truly show the full picture of your sugar levels? You are certainly not alone. For many people managing or preventing diabetes, accuracy is a top concern. What good is real-time data if it is unreliable?
This article breaks down CGM Accuracy MARD. It explains what accuracy means for your CGM device. We look at what affects it. We also explore why the Sibionics GS1 is a trusted option in Kenya.
CGM Accuracy MARD refers to how closely a glucose monitor‘s readings match actual glucose levels in your bloodstream. Importantly, CGMs measure glucose in the interstitial fluid just under your skin. This is slightly different from blood readings. Modern CGMs, however, have greatly closed this gap.
Accuracy matters greatly. Correct glucose data helps you make smart decisions about food, activity, and medicine. A minor error could cause you to take too much or too little insulin. This is especially vital for people on insulin treatment.
The standard way to measure CGM Accuracy MARD is called the Mean Absolute Relative Difference (MARD). This calculation compares the CGM device readings to lab-grade blood glucose values. A lower MARD percentage indicates better accuracy. Therefore, like in golf, a lower score is better.
For reference, most good modern CGMs have a MARD between 8% and 10%. This means the readings are typically within 10% of the true glucose value. This is a massive improvement over older devices. The Sibionics GS1 glucose sensor boasts a low MARD, making it competitive globally. This offers confidence to users and doctors.
Even the best real time glucose monitor can be influenced by certain factors:
Understanding these factors helps you trust your device in the right context.
When your glucose levels change fast, you need a glucose sensor that keeps up. This happens when you exercise or eat a high-carb meal. In such moments, CGM Accuracy MARD is more than just a specification. It becomes peace of mind.
Real-world usage shows the Sibionics GS1 performs with great stability. It delivers consistent and timely insights. This is true whether you are fasting, exercising, or managing post-meal spikes. This is a key reason many people are switching to this device.
The Sibionics GS1 CGM device is certified and approved locally. It has the CE-mark and is registered with Kenya’s Pharmacy and Poisons Board. Therefore, it is not only accurate but also affordable. This makes it an accessible choice in the market.
Key advantages include:

Every health decision counts when managing diabetes. From diet to medication, your glucose data is your guide. Consequently, CGM Accuracy MARD is a critical factor when choosing a device. You need a tool that you can trust completely.
The Sibionics GS1 smart glucose meter was designed for reliability. It is a powerful tool for transforming your health.
If you are only using a finger-prick device, or if your current diabetes patch is unreliable, now is the time to switch.

A: Most top-rated CGM devices are accurate enough for daily decisions. However, if a reading does not match how you feel, you should confirm it with a finger-prick test.
A: No. Factors like hydration, sensor site, and personal habits can affect your results. Proper placement and consistent use significantly boost reliability.
A: If your CGM device is factory-calibrated, like the Sibionics GS1, daily checks are not necessary. It is wise to test occasionally, especially when symptoms do not match the reading.
A: Yes. Lying directly on the sensor can temporarily restrict blood flow to the area. This results in a “compression low” and a false reading on your smart glucose meter.
A: A MARD below 10% is generally considered excellent for a real time glucose monitor. Values below 8% are best-in-class, showing very high accuracy.
A: CGMs measure interstitial fluid, which lags slightly behind blood glucose. This lag is usually only 5–10 minutes. This means the reading may be a little behind during fast drops or spikes.
A: Yes. The Sibionics GS1 holds the CE-mark. This means it meets European health, safety, and performance standards, which are recognized worldwide.
A: Modern glucose sensors are designed to maintain their accuracy for their entire life. The Sibionics GS1, for example, is reliable for the full 14 days.
A: Yes. Severe irritation or infection at the sensor site can affect how the sensor works. You should remove the sensor and apply a new one to a clean site if this occurs.
A: You can find the official MARD and other performance data on the Sibionics official site or in the product’s instructions for use. The MARD is listed as 8.83% in published reports.
