Types of blood glucose meters
There are a number of blood glucose meters marketed in the US. All of them must meet the minimum standards set by the US FDA, which are based on standards set by the International Organization for Standardization (ISO).
Key features that you may want to consider and which differentiate different models, include2:
- Audio capability. Monitors with sound systems are suited to people who have vision problems or issues that make reading a screen difficult.
- Performance in low or high temperatures. Temperature is one of the factors that can affect the accuracy of test results. Some monitors are designed to perform better in high heat environments and others are designed to perform better in colder temperatures.
- Display lighting. Getting a screen that is backlit is a good idea, as this makes it easier to see the display in low light or dark.
- Memory. Different units have different size memory capabilities for storage of test results. Memory sizes range from units that store 100 readings to those with large memories that store up to 5,000 readings.
- Required blood drop size. Monitors differ in the amount of blood they require for testing from amounts as small as 0.3 microliters to as much as 1.5 microliters (see below for examples of blood drop sizes).
- Size and handling. The size and handling of a monitor is an important consideration that affect how easily you can transport your unit (whether you can carry it in your pocket or purse) and how easy it is to use. Monitoring units vary widely in the total size of the unit, the size of the display, how easy it is to operate (the size of buttons or switches), and whether the unit allows the use of an attached disk or drum of test strips to eliminate the need for inserting individual strips.
- Cost of test strips. The cost of test strips is an important consideration in purchasing a monitor. Even if you get a free monitor from your doctor or through a special manufacturer offer, you will still have to purchase test strips regularly and this can be costly, depending on your insurance and pricing in your region. Test strips can range from .30 to $1.70 per strip.
- User coding. Whether the unit requires manual entry of user coding for test strip vials.
- Downloadable results. Many monitoring units offer the capability of downloading test results.
- Wireless functionality. Some monitoring units provide a wireless bluetooth computer interface.
- Expanded testing function. Some monitors measure not only blood glucose, but blood pressure and blood ketones, as well. Additionally, some units are designed to communicate with insulin pumps.
