If you have diabetes, you know monitoring and controlling your blood sugar is one of the most important parts of managing the disease. Whether you have type 1 diabetes or type 2 diabetes, accurate testing can not only help you make adjustments to your diet and daily routine, but it can also help reduce symptoms and prevent possible diabetes health complications, such as nerve damage (neuropathy) and kidney problems. But to properly monitor blood sugar, you’ll need a functioning, high-quality blood sugar monitor (also called a glucose meter). All of these monitors work similarly, but some models include features and options that may be better suited to your specific needs. Speaking with your doctor or a certified diabetes educator is the best way to find a blood sugar monitor to match your health goals and budget.

Some Features to Look for in a Blood Sugar Monitor

Accuracy Some tests have found monitors to be off by as much as 11 percent, which can make managing diabetes with precision trickier. Something to keep in mind is that blood sugar monitors must be calibrated to each batch of test strips you purchase, either by entering a code or downloading a smartphone app. If done incorrectly, your results won’t be accurate.
