Advantages of BGMs:
- Affordability: Generally less expensive compared to CGMs.
- Accuracy: Provide highly accurate readings when used correctly.
- Portability: Small and easy to carry.
- Easy to use: Simple operation with minimal training.
Disadvantages of BGMs:
- Requires finger pricking: Can be painful and inconvenient for some.
- Not continuous: Provide readings only at specific times and don't provide trends.
- Ongoing Cost: Need to purchase test strips and lancets regularly.
Continuous Glucose Monitors (CGMs)
CGMs offer a more modern approach by measuring glucose levels continuously throughout the day and night. They involve inserting a small sensor just under your skin. Here's how it works:
- Sensor Insertion: A tiny sensor is inserted beneath the skin, typically on the abdomen or upper arm.
- Glucose Monitoring: The sensor measures interstitial fluid glucose levels and transmits data wirelessly to a receiver or smartphone.
- Real-time Data: Provides continuous, real-time glucose readings and trends throughout the day.
Advantages of CGMs:
- Continuous Data: Provides real-time, dynamic glucose data, allowing you to see patterns and trends.
- No Finger Pricking: Eliminates or reduces the need for finger prick blood samples.
- Alerts and Alarms: Can be set to alert you of highs and lows.
- Improved Control: Enables more precise adjustments to insulin doses and lifestyle changes.
Disadvantages of CGMs:
- Cost: More expensive than traditional BGMs.
- Requires Insertion: Insertion of the sensor can be bothersome to some.
- Calibration Required: Some CGMs need calibration with finger stick measurements.
- Not always 100% accurate Can have some lag compared to real blood samples, depending on device
| Monitor Type | How It Works | Advantages | Disadvantages |
|---|---|---|---|
| Traditional Blood Glucose Meter | Requires blood from finger prick, placed on test strip to get a reading | Affordable, accurate, portable, easy to use | Requires finger pricks, not continuous, ongoing cost for strips and lancets |
| Continuous Glucose Monitor (CGM) | Tiny sensor under skin to measure interstitial fluid glucose, data transmitted | Continuous data, minimal finger pricks, alerts for highs and lows, better management, see trends | More expensive, sensor insertion may be bothersome, may require occasional calibration, lag compared to BGMs |
Key Features to Consider When Choosing a Blood Sugar Monitor
When selecting a blood sugar monitor, consider the following features:
Accuracy and Precision
The accuracy of a glucometer is paramount. Look for a device that meets the ISO 15197:2013 standard for accuracy. This standard ensures that the readings fall within a specified range of error compared to a laboratory blood test. Precision refers to the consistency of results from multiple tests. A reliable monitor will give consistent results, making it easier to track trends and patterns in your glucose levels. The higher the accuracy and precision, the more dependable your data will be for managing diabetes.
