How to Choose a Glucose Meter That Fits Your Lifestyle

How to Choose a Glucose Meter That Fits Your Lifestyle

If you have diabetes, regularly testing your blood glucose levels is an essential part of your everyday life. Since making sure your levels are in a healthy range is a critical part of your overall wellbeing, choosing a blood glucose meter that is accurate and reliable is an absolute must.

Here are 10 factors to consider when looking for a glucose meter:

10 Blood Glucose Meter Features to Consider


Your blood glucose readings will affect your insulin doses and diet choices, making accurate results from a reliable device crucial for your health.

Surprisingly, a recent study found that not all FDA-approved glucose meters meet accuracy standards. Of the top commercially available meters, a whopping 66% didn’t pass accuracy tests!

Since every glucose meter on the market has varying technology and accuracy performance, your blood glucose readings will likely fluctuate from one meter to another. You should pick one meter and stick with it for your daily management to ensure you receive consistent readings for making treatment decisions.

There are also several factors that can affect accuracy:

  • Variations in the proportion of red blood cells in your blood (your hematocrit)
  • Environmental conditions (altitude, temperature)
  • Manufacturing variability

To ensure that your device is reliable, make sure it utilizes the most innovative technology possible to detect and correct these variations.

Blood Sample Size

The larger blood sample a meter requires, the bigger the blood drop you will need to provide. This can cause difficulties if you have poor circulation or other health conditions, and can sometimes cause an increase in errors or wasted test strips if you can’t get a big enough blood drop.

Choosing a meter that only requires a micro-sized sample — such as 0.5 microliters or less — can be helpful and enable you to use a more comfortable lancing depth and lancet size.

If you plan on testing your glucose levels several times throughout the day, a lancet with a lower gauge (larger finger prick) might become painful. For frequent testing or to get a smaller blood sample, you may able to use a higher gauge lancet (like these 33G ones) which many people find to be less painful.

Ease of Use

If your blood glucose meter is too complicated, takes too long to read, or requires coding, you’ll be less likely to reach for the device when it’s time to test. And that defeats the entire purpose of the meter!

Choosing a simple blood glucose meter is the best motivation for testing as often as you need, so make sure you’re comfortable with the design and technology. Also, check if there are any helpful features — like testing reminders or hypoglycemic and hyperglycemic alarms — that will make your life easier.

Design/Form Factor

The design and form of your meter goes hand-in-hand with its functionality. Modern-day meters come in various shapes and sizes, so there’s definitely one that will suit your lifestyle.

Here are a few questions to ask yourself before you choose a meter:

  • Would you prefer a compact meter for discreet, on-the-go testing or a larger device that’s easier to grip and hold?
  • Are the numbers on the display large enough to read?
  • Does the display make it easy to view results in dim lighting or at night?

No Coding

Some blood glucose meters require manual coding, which means inputting a code every time you start using a new pack of test strips. A meter that is “No Code” means it’s already calibrated, saving you an extra step in the testing process.

Most brands are migrating toward code-free technology, but there are still a few on the market that require it for calibration. It’s important to correctly match the code as an error could cause inaccurate readings. If you’d prefer a code-free device, make sure the one you choose clearly states that it’s “No Code.”

Data Capabilities

How do you want to maintain your readings? Do you prefer writing them down by hand every day or would storing them all on the meter be ideal?

Fortunately, today’s blood glucose meters include a world of options. What you need to check is the amount of storage for each device you’re considering since this will vary widely across brands. Some can hold hundreds or thousands of readings as well as time and date stamps, while others might only be able to store a maximum of 100.

There are also meters that can keep track of averages by certain time periods (usually 14, 30, or 90-day intervals), the time of day, and mealtimes. This is a useful feature that automatically tracks glucose level averages, so you can have a big-picture view of your health patterns.


Meters have become very tech-savvy, with many offering Bluetooth® wireless connections allowing you to more easily capture, analyze, and share your readings. Some meters also have a data download feature that lets you transfer results through a data port.

There are mobile management apps that wirelessly connect a meter and smartphone to automatically sync and store your readings. Even if you don’t use a meter with connectivity capabilities, many mobile apps allow you to record your readings manually. This makes it easy to track your blood glucose, share readings with your family and/or physicians, and identify certain trends in your readings.

Speed of Results

Waiting an eternity for results — especially if you’re testing multiple times a day — is incredibly inconvenient. Meters will typically list their average testing time to give you an idea of how long you’re likely to wait. Most people find a test of 5-6 seconds or less to be ideal.


The first and most important note about the affordability of a blood glucose meter is that the price will be one flat cost, but the test strips will need to be purchased on an ongoing basis.

The cost of the meter will depend on its features. For example, a device with Bluetooth capabilities will be a bit more than one without. Whatever the capabilities, the meter should last for at least a few years.

Many major brands have free meter programs that offer an upgrade to the latest device at no cost, but there are certain qualifications you must meet.

Test Strips

Test strip costs will vary based on the amount you need and the brand. If you’re testing several times throughout the day you’ll need more strips, so you should factor in these costs.

Health Insurance

The cost of a meter will depend on whether you’re going through your health insurance. On average, copay costs are between $20 and $80. However, your insurance plan can dictate the brands that are available to you, which can be limiting.

You don’t necessarily have to go through your insurance. Many meters are affordable enough to purchase outside of a prescription. Some are even cheaper and offer features and benefits that others may not.

Alternate Site Sampling

Some meters will let you collect a blood sample from parts of your body besides your finger, like your hand, upper arm, calf, or thigh. If you test a lot throughout the day, this can be a huge benefit that gives your fingers a much-needed break.

However, it’s important to note that test results from alternate sites are considered less accurate than testing using your fingertip. This is because of physiological differences in the circulation in these areas.

Be aware that some situations may not make alternate site testing feasible. You shouldn’t use alternate test sites to:

  • Calibrate a continuous glucose monitor (CGM)
  • Check for hypoglycemia or hyperglycemia
  • Test your levels within 2 hours of eating, taking medication or insulin, or exercising

Always ask your doctor before you use alternative testing sites.

We recommend thoroughly evaluating all of the above features before choosing a blood glucose meter. There are dozens of options out there, so you’re sure to find a meter that’s right for your unique lifestyle!
