Three glucose monitors on blue background.

Home glucose monitors can help you keep tabs on your diabetes and lower your risk of complications. Along with treatment, using a home monitor can help you identify the things that make your blood sugar increase or decrease, from exercise to illness, stress to dehydration, and more.

The Centers for Disease Control and Prevention (CDC) recommends checking your blood sugar as advised by your doctor. How often you should check depends on a number of things, including:

  • The type of diabetes you have.
  • What are the medications you are taking?
  • How many meals do you eat?

Some doctors may recommend you only test a few times a day, while others may think continuous monitoring is more appropriate, as each situation is unique and may change over time.

Selecting a great diabetes monitor can be difficult because of all the options. We rounded up the best monitors available. Before you start, it is a good idea to talk to your doctor about these options.

Above all, we included glucose monitors that are reportedly the most accurate. Since home meters are designed to help you monitor your glucose in between laboratory work from your doctor’s visits, it’s important that your device provides the most accurate results possible.

Getting as close to the quality of the test as possible can help provide peace of mind and better diabetes management.

Other items we looked at include.

  • Consistent performance. While accuracy is of utmost importance, consistency is key. The meters on this list provide consistent results from test to test.
  • Price and overall affordability. Meters (and accessories) range in price considerably. The ones on this list are either low cost out of pocket or available through insurance.
  • Insurance coverage. Yes — insurance. It’s always a good idea to check with your insurance carrier to see which home glucose monitors are covered in part or in full by your policy.
  • Accessibility. Monitors on this list let you hear or feel alarms when needed or offer other helpful accessibility features, so they aren’t all read-only.
  • Durability. Whatever glucose monitor you choose, it needs to stand the test of time and perform reliably even after repeated use.
  • Portability. Most if not all the glucose meters on this list include carrying cases or are otherwise portable, so they can go wherever your life takes you.
  • Special features. Whether it’s Bluetooth connectivity you’re looking for or discreet vibration alarms, you’ll find a variety of special features included in these picks.
  • Overall ease of use. Reading your blood sugar should be simple, even if you’re just starting out. We chose devices that are straightforward and easy to use.
  • User experiences and reviews. We also took into account reviews, both good and bad, from real people like you who are using these readers in their everyday lives.

We included the meters in a variety of price points. The cost of bloodglucose meters can be different depending on features, insurance coverage, and location. The cost is subject to change over time, so be sure to check with your carrier for the most accurate price.
