Types of Blood Glucose Monitors

There are several types of blood glucose meters available, each with its own features, advantages, and disadvantages. Understanding these differences can help you select the most suitable monitor for your lifestyle and needs.

Traditional Blood Glucose Monitors

Traditional meters use a small blood sample to measure glucose levels. They consist of several components:

• The Meter: A handheld device that reads the test strip.
• Test Strips: Disposable strips where a blood sample is applied.
• Lancing Device: Used to prick the skin and obtain a blood drop.
• Lancets: Small, sharp needles that go into the lancing device.

How they work: A tiny drop of blood is applied to the test strip. The meter then processes the chemical reaction on the strip to display a glucose reading, typically in mg/dL (milligrams per deciliter) or mmol/L (millimoles per liter).

Pros:

• Generally affordable.
• Accurate results.
• Widely available.

Cons:

• Requires regular finger pricking, which can be uncomfortable for some individuals.
• Test strips and lancets need to be purchased regularly.
• Can be less convenient compared to other types.

Continuous Glucose Monitors (CGMs)

CGMs are wearable devices that provide real-time glucose readings throughout the day and night. Unlike traditional monitors, they do not require regular finger pricks. CGMs consist of two main components:

• Sensor: A small filament inserted under the skin, typically in the abdomen or arm.
• Transmitter: A device worn on top of the sensor, which wirelessly sends glucose readings to a receiver or smartphone.

How they work: The sensor continuously measures glucose levels in the interstitial fluid (the fluid between the cells), which reflects the glucose level in the blood.

Pros:

• Real-time data with continuous monitoring.
• No finger pricking required (except occasionally for calibrations).
• Provides valuable insights into blood sugar trends and patterns.

Cons:

• More expensive compared to traditional meters.
• Requires insertion of a sensor, which may be uncomfortable for some.
• Accuracy may require calibration using finger prick measurements.

Flash Glucose Monitors (FGMs)

Flash Glucose Monitoring systems are a middle ground between traditional and continuous monitors. Similar to CGMs, FGMs have a sensor that is inserted under the skin; however, they do not continuously transmit data. Instead, the user must "scan" the sensor with a handheld device to obtain a glucose reading.

How they work: A sensor is inserted under the skin and uses near-field communication technology. Data is scanned using the sensor reader or a smartphone app.

Pros:

• No finger pricks for routine glucose checks.
• Provides glucose trends and patterns.
• Less expensive compared to CGMs.

Cons:

• Requires scanning to obtain readings.
• Accuracy may need to be verified using finger prick measurements.

Key Features to Consider When Choosing a Monitor

Choosing the right blood glucose monitor involves careful consideration of its features. Here are some crucial aspects to evaluate:

1. Accuracy:

   • The monitor should provide consistent and reliable results.
   • Look for meters that meet ISO (International Organization for Standardization) standards.
   • Scientific studies on meter accuracy usually are published in respected publications like the Journal of Diabetes Science and Technology and may include data comparing different brands. A few years ago, some data compared different brands of test strips as well, and the conclusion was that brand specific test strips work best for the brands they are made for.
   • A study published in the Diabetes Technology & Therapeutics journal analyzed the variability and errors from different types of BG meters. For the finger stick meters, there was shown to be a variance in accuracy based on the testing conditions - specifically the temperature and humidity.
   • Always check user reviews and compare with research information when selecting a device.

2. Ease of Use:

   • A large, clear display and simple menus make the meter user-friendly.
   • Consider the size and design, particularly if portability is needed.
   • Ergonomic considerations are important, especially for older users or those with limited dexterity.

3. Data Storage and Management:

   • Many meters can store a large number of readings and provide averages.
   • Data transfer capabilities, such as Bluetooth or USB connections, allow for easy sharing with healthcare providers.
   • Cloud-based or application-based options can offer enhanced analysis.

4. Cost:

   • Compare the initial cost of the meter and the ongoing cost of test strips, lancets, or sensors.
   • Check insurance coverage and compare pharmacy costs before making the decision to purchase.
   • Consider that in addition to the monitor itself, the test strips will be needed ongoing, so choosing a brand that meets your budget is important.

5. Testing Method and Pain Factor:

   • Traditional meters require finger pricks, while CGMs and FGMs use sensor insertions.
   • The lancing devices should be designed to minimize discomfort when drawing blood.
   • If minimal finger pricks are a priority, then consider using an FGM or CGM.

6. Additional Features:

   • Some meters may offer features such as reminders, meal markers, and hypo/hyper alerts.
   • The availability of phone app integrations or Bluetooth transfer features may improve user satisfaction.
