Glucose meters come with testing strips, lancets to prick your finger, and a device to hold the needle. The kit may include a logbook, or you might be able to download the readings onto your computer.

Meters vary in cost and size. Some have added features to suit different needs and preferences. These may include:. Before you begin, wash your hands thoroughly to prevent infection at the finger-prick site.

If you use alcohol wipes instead of washing, be sure to let the site dry before testing. Next, put a testing strip into the meter. Prick your finger with the lancet to get a small drop of blood.

To decrease the discomfort in your finger, you can use the side of your fingertip instead of the tip. Apply some blood to the test strip you inserted into the meter. Your meter will analyze the blood and give you the blood glucose reading on its digital display, usually within a minute.

Finger pricks rarely require a bandage, but you may want to use one if bleeding continues beyond a few drops. If you have type 1 diabetes , you may need to test your blood glucose four or more times per day, including before and after meals and exercise.

You may need to test more often when you are sick. If you have type 1 or type 2 diabetes , your doctor will let you know when and how often to test your blood glucose.

According to the American Diabetes Association , most adults with type 1 or type 2 diabetes who are not pregnant should aim for blood sugar levels in the following ranges:. But these are general guidelines and are not for everyone. Ask your doctor about your individual target levels.

Regular blood glucose monitoring is an essential tool to help you manage your diabetes. Regular glucose monitoring is one way you can learn more about your diabetes. Your doctor will calculate your target blood glucose range based on your age, your type of diabetes, your overall health, and other factors.

Without proper treatment, high blood sugar levels can lead to long-term complications such as:. Additionally, low blood sugar can lead to serious complications such as seizures and coma. Risks from the blood glucose test are minimal and much less significant than the risks of not monitoring your blood sugar levels.

You should never share needles or finger-stick devices for any reason. Sharing testing supplies with someone can increase your risk of contracting or transmitting viruses such as:.

Regular blood glucose monitoring is a way to gather information about how your blood sugar levels respond to your day-to-day activities.

Like the FreeStyle Libre and Eversense, the Guardian Connect sensor is worn on your arm to measure glucose via interstitial fluids. But unlike any other CGM currently on the market, the Guardian Connect compiles time in range data.

This data tells you how long your glucose is in your personal ideal range on any given day. You also need to change out your sensor every 7 days. This straightforward product allows you to program four reminder alarms, and the results can be processed in as quickly as 4 seconds.

You can also store up to test results on the device. The TrueMetrix meter is available at Rite Aid stores and online without a prescription. Keep in mind that you will also need to purchase lancets and test strips separately, both of which Rite Aid also sells.

Similar to the Rite Aid TrueMetrix glucose meter, this version from Walgreens uses blood samples via a traditional finger-sticking process.

What sets it apart from the original TrueMetrix is its Bluetooth capabilities to deliver results to your smartphone. It works on both Android 4. Additionally, this Bluetooth version allows you to store twice as many test results: 1, at a time.

It claims to process your results in about 4 seconds. In addition to the cost of the meter, you will still need to buy lancets and test strips from the same brand.

Walgreens sells the meter and accessories without a prescription. You may consider the Libre, G6, Guardian Connect, or Eversense based on their features, as well as the accuracy and duration of sensor wear. While most insurance and Medicare do cover CGMs, these monitors are more expensive overall.

Depending on your insurance, they may offer coverage for one type of CGM but not another. With a prescription, you may be able to buy a CGM from a medical supply store online. If you do decide to purchase a glucose meter or monitor online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately.

However, you do need one for a continuous glucose monitor. Some smartwatches can connect to CGM systems, allowing you to check your readings on your watch. But none are capable of taking blood glucose readings directly. These seven glucose meters offer benefits — and some drawbacks — to consider when making your ultimate selection.

You can also talk about these monitors with your doctor. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Type 2… READ MORE. It is generally unnecessary in people who manage their diabetes with diet alone or who take medications that do not cause hypoglycemia, especially if they have reached their glucose goals.

Your health care provider can help you determine how frequently to check your glucose based on your situation. Most people with type 2 diabetes who perform glucose monitoring use BGM.

For people taking insulin, CGM may be used if available and affordable. See 'Who should use CGM? How to check your blood glucose — The following steps include general guidelines for testing blood glucose levels.

However, because the instructions can vary between devices, it's best to check the package insert for your glucose meter or talk with your health care provider.

It's important to never share monitoring equipment or fingerstick devices, as this could lead to infection. Lancets that are used more than once are not as sharp as a new lancet and can cause more pain and injury to the skin. Alternate sites are often less painful than the fingertip.

However, results from alternate sites are not as accurate as fingertip samples. This should not be a problem if you always use the same site. However, when your blood glucose is rising rapidly eg, immediately after eating or falling rapidly in response to insulin or exercise , it's more accurate to use the fingertip, as testing at alternate sites may give significantly different results in these situations.

If you have difficulty getting a good drop of blood from your fingertip, try rinsing your fingers with warm water and shaking your hand below your waist.

This can help get the blood flowing. The results will be displayed on the meter after several seconds. Blood glucose meters — There is no single blood glucose meter that is better than others.

Your health care provider or pharmacist can help you choose a meter based on your preferences as well as other factors like cost, ease of use, and accuracy; it should be one that is approved by either the International Organization for Standardization or the US Food and Drug Administration FDA.

Medicare also covers costs of BGM. Accuracy of home BGM — Blood glucose meters are reasonably accurate. However, there can be some variability between meters, so it is always wise to use caution and common sense.

If you get a result that does not fit with how you feel for example, if it says your blood glucose is very low but you don't have any symptoms , take a second reading or use an alternate method for testing your blood glucose such as a different meter.

Blood glucose meters are least accurate during episodes of low blood glucose. See "Patient education: Hypoglycemia low blood glucose in people with diabetes Beyond the Basics ". The accuracy of BGM can be affected by several factors, including the type of blood glucose strip and meter.

Inaccurate readings can be caused by the use of expired strips, improper storage of strips exposure to high temperature and humidity , inadequate cleansing of your skin, and ingestion of vitamin C and acetaminophen. It's a good idea to check the accuracy of your blood glucose meter occasionally by bringing it with you when you have an appointment to get blood testing.

This way, you use your home monitor to check your blood glucose at the same time that blood is drawn and compare the results. If the results differ by more than 15 percent, there may be a problem with your meter or other equipment; your provider can help you figure out what's going on and how to correct the problem.

Help for people with vision impairment — People with vision impairment a common complication of diabetes sometimes have difficulty using glucose meters. Meters with large screens and "talking" meters are available.

If you have impaired vision, you can get help from the American Association of Diabetes Care and Education Specialists ADCES at Continuous glucose monitoring CGM is a way to monitor your glucose levels every 5 to 15 minutes, 24 hours a day.

Because of reliability issues, warm-up periods, and the need to calibrate some of the devices, CGM does not eliminate the need for at least occasional fingersticks. CGM systems are described in detail above see 'Continuous glucose monitoring' above.

Who should use CGM? CGM systems are most often used by people with type 1 diabetes. Periodic use of CGM can also help you and your health care provider determine when your glucose is low or high and how to adjust your medication doses or food intake to prevent these fluctuations.

Devices that combine an insulin pump with a CGM system are also available. See "Patient education: Type 1 diabetes: Insulin treatment Beyond the Basics ".

Advantages — There is evidence that people with type 1 diabetes who use a CGM system consistently and reliably rather than blood glucose monitoring [BGM] have modestly better managed blood glucose levels. The "real-time" CGM devices automatically display your glucose level every five minutes, using numbers, graphics, and arrows so you can easily tell if your level is increasing, decreasing, or stable figure 3.

The receiver recording device can also be set to trigger an alarm if your glucose level gets above or below a preset level, which can be especially helpful for people who cannot feel when they have low blood glucose also known as "impaired awareness of hypoglycemia".

Most CGM systems permit real-time "sharing" of your CGM readings with others eg, family members or caregivers. Some, but not all, of these intermittently scanning CGM devices are able to alert you of low or high glucose readings. You can download glucose results from the CGM system to your computer, tablet, or smartphone, allowing you to see glucose trends over time.

If you take insulin, your health care provider can help you figure out how to use this information to adjust your insulin dose if needed. Drawbacks — CGM systems may show lower glucose values than blood glucose meters, especially when blood glucose levels are rapidly rising.

In addition, the costs associated with CGM are greater than those of traditional glucose meters. Not all continuous glucose meters and supplies are covered by commercial health insurance companies.

Glucose testing — The results of glucose testing with blood glucose monitoring BGM or continuous glucose monitoring CGM tell you how well your diabetes treatments are working. Glucose results can be affected by different things, including your level of physical activity, what you eat, stress, and medications including insulin, non-insulin injectable medications, and oral diabetes medications.

To fully understand what your glucose levels mean, it is important to consider all of these factors. When keeping track of your results, you should include the time and date, glucose result, and the medication and dose you are taking. Additional notes about what you ate, whether you exercised, and any difficulties with illness or stress can also be helpful but are not generally required every day.

You should review this information regularly with your health care provider to understand what your results mean and whether you need to make any changes to better manage your glucose levels.

Need for urine testing — If you have type 1 diabetes, your health care provider will talk to you about checking your urine for ketones. Ketones are acids that are formed when the body does not have enough insulin to get glucose into the cells, causing the body to break down fat for energy.

Ketones can also develop during illness, if an inadequate amount of glucose is available due to skipped meals or vomiting. Ketoacidosis is a condition that occurs when high levels of ketones are present in the body; it can lead to serious complications such as diabetic coma.

Urine ketone testing is done with a dipstick, available in pharmacies without a prescription. If you have moderate to large ketones, you should call your health care provider immediately to determine the best treatment. You may need to take an additional dose of insulin, or your provider may instruct you to go to the nearest emergency room.

Meters that measure ketone levels in the blood are also available, but due to their cost, urine testing is more widely used. ADJUSTING TREATMENT. Checking your glucose either with blood glucose monitoring [BGM] or continuous glucose monitoring [CGM] provides useful information and is an important part of managing your diabetes.

If you use insulin, your glucose results will help guide you in choosing the appropriate doses from meal to meal. When you first start treatment for diabetes, you will need to work with your health care provider as you learn to make adjustments in treatment.

However, with time and experience, most people learn how to make many of these adjustments on their own. Your health care provider is the best source of information for questions and concerns related to your medical problem.

The Signos system integrates with the Apple Watch, allowing you to track your nutrition, sleep, and activity in a single app. Signos leans heavily into weight loss promotion territory. Levels is an app that uses CGM data to provide users with insights into how their diet affects their health.

The app supplies real-time blood glucose level data and syncs with Apple Health kit. As you track your glucose levels, the app will provide daily recommendations for sleep, exercise, and stress management.

Devices that are compatible with the Levels ecosystem include Dexcom G6 and Freestyle Libre. The FreeStyle Libre first debuted on the market in Like other CGMs , it uses interstitial fluids instead of blood to measure blood glucose.

You use the Libre by wearing a sensor on your upper arm. To keep the Libre system working, you have to reapply a new sensor to your arm every 14 days. One downside to this CGM is that it can be a little confusing to keep track of their latest models that have the same names. Some users also report inaccurate readings as well as skin irritation from applying the sensors.

The Dexcom G6 is a sensor you wear on your abdomen that transmits information to a corresponding app you can download on your phone, tablet, or smartwatch.

Users like the fact that the sensor transmits this data automatically every 5 minutes. What sets the Dexcom G6 apart from other types of CGMs is its ability to complement other devices you might have for your diabetes management. These include insulin pumps.

One of the most common complaints is that you have to change out your sensor every 10 days, versus longer wear on other CGM devices.

The manufacturer, Senseonics, a publicly traded company, started experiencing challenges in Senseonics has scaled back its workforce but continues to support the Eversense system.

Like the FreeStyle Libre, Eversense measures interstitial fluids via a sensor applied to your upper arm. The key difference is that the sensor is implanted subcutaneously, or under the skin, and is worn for 90 days at a time.

Once the sensor is applied, the Eversense system sends data to your smart device automatically every 5 minutes. It also alerts you via a vibration alarm if your blood glucose falls out of your ideal range. Overall, users appreciate how this sensor is changed every 90 days versus 7 to 14 days like other brands.

However, some have experienced sensitivity alerts when wearing the sensor in direct sunlight. The PROMISE study evaluated the Eversense, concluding that the monitor sustained accuracy and safety up to days.

Like the FreeStyle Libre and Eversense, the Guardian Connect sensor is worn on your arm to measure glucose via interstitial fluids.

But unlike any other CGM currently on the market, the Guardian Connect compiles time in range data. This data tells you how long your glucose is in your personal ideal range on any given day. You also need to change out your sensor every 7 days.

This straightforward product allows you to program four reminder alarms, and the results can be processed in as quickly as 4 seconds. You can also store up to test results on the device. The TrueMetrix meter is available at Rite Aid stores and online without a prescription.
