For a diabetic, a blood sugar meter—also known as a glucose meter or simple, glucometer—is an essential tool. When a device becomes a part of our every day habits, qualities such as convenience, portability and easy-of-use become important. Thanks to recent innovations, glucose meters have become smaller and smaller, fitting neatly into our lives and integrating with our technologies. What makes a good one for you will likely include these and other qualities.


Familiarity can be an important factor when choosing a glucose meter. A manufacturer or brand you know and trust can be important for your selection. Recommendations from your health care team is also likely a factor in choosing, as is coverage offered by your health insurance. Coverage intersects with cost considerations, as well. Tracking your numbers is important, which you can do yourself or opt for a glucose meter that will handle that storing and tracking task for you.

When choosing a glucose meter, it is important to determine which features are most important for your needs. Not all blood sugar meters are the same. For example, while the majority of meters have the ability to download your test results to a computer, only a few have a backlight display. A backlight can be important if you often test your blood at night. Newer innovations also include convenient integration with your smartphone.

Blood Sample

One feature that is especially important to many people is the size of the blood sample taken . Blood samples range from a sizable 3.0 microliters down to a very small 0.3 of a microliter. A smaller sample is of particular concern for parents of children with diabetes.

There are also meters that will check your blood sugar and your blood ketones.

Other meters will check your blood pressure in addition to your blood sugar. Some meters have substantial storage of previous test results while others do not. So, finding the right blood sugar meter may start with determining your needs.

The chart below lists meters that require only a 0.3 microliter blood sample, which is currently the smallest amount any blood sugar monitor can measure. Only a handful of meters have this technology. If blood sample size is important, check out these meters.
