Daily blood sugar testing is a vital component of any successful diabetes management plan. It can help determine if you have your blood sugar under control, while also helping identify patterns that can lead to a spike or crash. It also reveals how factors like stress and exercise can impact your blood sugar, and it assists you in examining the effectiveness of any diabetes medications you may be taking.

While the frequency and cadence of your blood glucose testing depends on your specific diagnosis and your physician’s recommendations, it’s up to you to select the glucometer—or at-home blood sugar-monitoring device—that will best support your needs.

The number one thing you should do before purchasing a glucometer is to check with your insurance company about what they will cover. But don’t just check the glucometer. Make sure you’re checking the testing strips compatible with the device. Taking your insurance coverage into consideration will not only help you narrow down devices, but it will also guide you to a budget-friendly and cost-effective option. 

Luckily, a wide variety of glucometers exist on the market today. From the simplest blood sugar readouts to Bluetooth-enabled devices that sync with your smartphone and come loaded with extra features, there is a glucometer out there for every person eager to self-manage their diabetes and avoid long-term complications.

In an effort to simplify your search, our experts combed through dozens of options and identified the nine best glucometers for monitoring your blood sugar. We’re confident that one of these devices will suit your medical needs, monthly budget, and personal preferences.

If you're looking for a kit that has everything you need to accurately read your blood sugar levels, AccuChek Aviva Plus Meter is a great starting point. But not every glucometer has an intuitive design. One Touch Ultra2 System is a user-friendly option that offers plenty of easy-to-follow tutorial videos so that you can guarantee an accurate reading. Ultimately, the device needs to work for your daily life, depending on your personal diagnosis. Consider what features will make monitoring your blood glucose levels feel less like a chore to find a glucometer that fits your lifestyle.

What to Look for in a Glucometer

Insurance coverage: Akankasha Goyal, an endocrinologist at NYU Langone Health, says the most important consideration when researching glucometers is if it will be covered under your insurance company. “It has to be cost effective at the end of the day because people check their blood glucose at least once or twice per day,” she says. 

You don’t just want to select a device that is covered under your health insurance, but you also want the test strips, or a portion of the strips, to be covered as they are the item that really adds up when it comes to price. So when purchasing a meter, pay attention to what specific test strips it requires and how expensive they would be under your health insurance. That should help you narrow down the options available on the market.

Accuracy: The quality of your glucometer and the quality of the testing strips used in your glucometer can dramatically impact the overall accuracy of your blood glucose monitoring tests. Some meters are known for giving readings that show blood glucose levels up to 15 percent higher or lower than they actually are. That variance is accepted by the Food and Drug Administration, but the more accurate readings you can get from your glucometer, the better.

Ease of use: Once you know what your insurance company will cover you can start to differentiate devices based on the additional features they offer. Considering most people need to use their glucometers multiple times per day, it’s important to pick one that you find easy and as comfortable as possible to use. For some, that means a very simple interface that just reports and records the numbers you need. For others, that means features like Bluetooth connectivity so you can easily keep track of your data on your smartphone.

Looking for a larger screen? Then you can likely eliminate any monitors that make it more difficult to read the numbers. Looking for a device easy to carry around? Then you should definitely consider size and where you would likely store the device when taking on the go. Regardless, your glucometer should empower you to manage your health successfully on a daily basis.

Data display: When using a glucometer, reading and understanding your blood glucose reports needs to be a quick and somewhat automatic process. Many people prefer LED screens with high contrast and large readouts so they don’t strain their eyes as they read off their numbers on the handheld device multiple times per day. It’s also important to pick a device with data review settings that feel intuitive to you so you can reduce the burden of frequent testing.
Storage size and retrieval: 
Most glucometers store about 50 to 100 readings, but there are others on the market that can store up to 500 readings. The difference can matter for some because more readings allow you to discover patterns in when your blood glucose levels dip and rise. Dr. Goyal recommends purchasing a device with more memory storage, but only if your insurance company covers the glucometer. 
Blood-sample size: 
Glucometers require different sizes of blood droplets on the test strips in order to accurately determine your blood glucose levels. “Less expensive meters tend to require a larger amount of blood,” says Matt Petersen, vice president of medical information and professional engagement at the American Diabetes Association. If pain is a key factor in your decision then you will want to consider a more expensive device that will allow for a smaller drop of blood. But if this consideration isn’t a deal breaker for you then you can likely get away with using a more inexpensive device that requires more blood. 

There are a lot of choices but fundamentally they all work. The choices come down to cost, your personal desire for the features, etc."—Matt Petersen, vice president of medical information and professional engagement at the American Diabetes Association
