Blood glucose monitoring -

A1C targets differ based on age and health. Also, more or less stringent glycemic goals may be appropriate for each individual. When you finish the blood glucose check, write down your results and note what factors may have affected them, such as food, activity, and stress.

Take a close look at your blood glucose record to see if your level is too high or too low several days in a row at about the same time. If the same thing keeps happening, it might be time to change your diabetes care plan.

Work with your doctor or diabetes educator to learn what your results mean for you. It can take time to make adjustments and get things just right.

And do ask your doctor if you should report results out of a certain range right away by phone. Keep in mind that blood glucose results often trigger strong feelings.

Blood glucose numbers can leave you upset, confused, frustrated, angry, or down. It's easy to use the numbers to judge yourself. Remind yourself that tracking your blood glucose level is simply a way to know how well your diabetes care plan is working, and whether that plan may need to change.

Checking urine for ketones is important when your blood glucose levels are high or when you are sick. Talk to your doctor to find out if or when you should check for ketones.

Breadcrumb Home Life with Diabetes Get the Right Care for You The Big Picture: Checking Your Blood Glucose. Who should check? People who may benefit from checking blood glucose regularly include those: taking insulin. who are pregnant. having a hard time reaching your blood glucose targets.

having low blood glucose levels. having low blood glucose levels without the usual warning signs. have ketones from high blood glucose levels. How do I check?

An artificial pancreas , also called an automated insulin delivery system AID , mimics how a healthy pancreas controls blood glucose in the body. A CGM, an insulin pump, and a software program that shares information between the CGM and insulin pump make up the artificial pancreas.

The CGM estimates glucose levels and wirelessly sends the information to a software program on a smartphone or insulin pump.

The program calculates how much insulin your body needs, and the insulin pump delivers the insulin when glucose levels rise higher than your target range.

On the other hand, if your glucose levels fall lower than your target range, the artificial pancreas can lower or stop the amount of insulin given by the insulin pump. The artificial pancreas is mainly used to help people with type 1 diabetes keep their glucose levels in their target range.

NIDDK has a long-standing commitment to funding research to better understand diabetes and improve the lives of people with the disease.

NIDDK-funded research helped scientists learn that glucose levels in the fluid between cells could be used to estimate blood glucose levels. NIDDK also supported the Diabetes Control and Complications Trial, which showed that people with diabetes could use blood glucose monitors at home to closely control their blood glucose levels and reduce their risk of health problems.

NIDDK conducts and supports clinical trials for many diseases and conditions, including diabetes. Trials look for new ways to prevent, detect, or treat disease and improve quality of life.

Clinical trials—and other types of clinical studies —are part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of CGMs, such as how CGMs could be made more sensitive, reliable, and comfortable to wear. Researchers are also studying how they might be used to manage different types of diabetes or other medical conditions.

Find out if clinical studies are right for you. Watch a video of NIDDK Director Dr. Griffin P. Rodgers explaining the importance of participating in clinical trials. You can view a filtered list of clinical studies that use CGMs and are federally funded, open, and recruiting at www.

You can expand or narrow the list to include clinical studies from industry, universities, and individuals; however, the National Institutes of Health does not review these studies and cannot ensure they are safe.

Always talk with your health care provider before you participate in a clinical study.

What are some features of continuous glucose monitors? What are the benefits of a continuous glucose monitor? What issues could you have while using a continuous glucose monitor?

What is an artificial pancreas? How does NIDDK support research on continuous glucose monitors? Clinical Trials on Continuous Glucose Monitors What is continuous glucose monitoring? Most CGMs send information without using wires to an app on a smartphone. Other differences between CGM models include whether the sensor is placed on the skin or is implanted how often the sensor has to be replaced how long it takes the CGM to warm up how you adjust the program settings For some CGM models, you may need to do a finger-stick test with a standard blood glucose monitor to calibrate the system and make sure the CGM readings are correct.

Many CGMs work with apps that have special features, such as ways to track the food and beverages you consume, your physical activity level, and the medicines you take the ability to download data onto a computer or smart device so you can easily see trends in your glucose levels an alarm that goes off when your glucose level is too low or too high, helping you prevent emergencies For safety, it is important to act quickly if a CGM alarm sounds when your glucose level is too low or too high.

Compared with a standard blood glucose meter, using a CGM can help you better manage your glucose levels every day have fewer low blood glucose emergencies need fewer finger sticks The CGM will create an alert and might display a graphic that shows whether your glucose level is rising or dropping—and how quickly—so you can choose the best way to reach your target range.

Checking your blood sugar level is one of the best ways to understand your diabetes. It helps you identify and track how different foods, medications, and activities affect your glucose levels. Keeping track of your blood glucose levels over time can also help you and your doctor make any necessary adjustments to your diabetes management plan. Contributor Disclosures. Please Blood glucose monitoring nonitoring Disclaimer at the Citrus aurantium plants of Blokd page. GLUCOSE TESTING OVERVIEW. If you have diabetes, you have an monitoriny Mindful alcohol consumption in your monitoting medical care glucosee monitoring your glucose sugar level is a key part of this. Although diabetes is a chronic condition, it can usually be managed with lifestyle changes, medication, and self-care measures. The main goal of diabetes treatment is to keep your glucose levels in the target range. Checking your glucose is one of the best ways to know how well your diabetes treatment plan is working.

Blood glucose monitoring -

If you use a CGM system, you will need to remove the sensor and replace it on a different part of your body approximately once every 7 to 14 days. Different CGM systems are available; one implantable sensor can last up to days, but it needs to be inserted and removed by a physician, nurse practitioner, or physician assistant.

FREQUENCY OF GLUCOSE TESTING. Studies have proven that people with diabetes who maintain normal or near-normal blood glucose levels reduce their risk of diabetes-related complications. Checking your glucose levels can play an important role in achieving your glucose goals and reducing the risk of complications.

See "Patient education: Preventing complications from diabetes Beyond the Basics ". Type 1 diabetes — For people with type 1 diabetes, frequent glucose testing is the only way to safely and effectively manage blood glucose levels.

People with type 1 diabetes may use blood glucose monitoring BGM with fingersticks and a glucose meter, or continuous glucose monitoring CGM. In people with type 1 diabetes, CGM is generally used if available and affordable.

See 'Methods of glucose monitoring' above and 'Continuous glucose monitoring' below and "Patient education: Type 1 diabetes: Overview Beyond the Basics ". Most people with type 1 diabetes who use BGM alone need to check their blood glucose level at least four times every day. If you use an insulin pump, give yourself three or more insulin injections per day, or are currently pregnant, you may need to test as many as 10 times a day or more.

See "Patient education: Care during pregnancy for patients with type 1 or 2 diabetes Beyond the Basics ". This way you will be able to access your testing equipment wherever you are, making it easier to manage your blood glucose.

Glucose monitoring is useful for people with type 2 diabetes who take insulin or certain medications that can cause hypoglycemia. 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.

This article will be updated as needed on our website www. The exact number of times depends on the type and amount of insulin you use.

Often, testing is advised before meals and at bedtime if you take more than one shot of insulin a day. You may need to test only before breakfast and sometimes before dinner or at bedtime if you use an intermediate- or a long-acting insulin.

You might not need to test your blood sugar every day if you manage type 2 diabetes with medicines that are not insulin. You also might not need to test daily if you manage the condition with diet and exercise alone.

A continuous glucose monitor, on the left, is a device that measures your blood sugar every few minutes using a sensor inserted under the skin. An insulin pump, attached to the pocket, is a device that's worn outside of the body with a tube that connects the reservoir of insulin to a catheter inserted under the skin of the abdomen.

Insulin pumps are programmed to deliver specific amounts of insulin automatically and when you eat. People living with diabetes may choose to use CGMs , especially people who have type 1 diabetes. CGMs measure blood sugar every few minutes. They use a device placed on the skin along with a sensor placed under the skin.

These disposable sensors last for 10 days to two weeks before they need to be changed. Other types of implanted sensors can last up to 6 months. CGMs include a wireless device worn on the body called a transmitter. The transmitter sends information from the sensor to a program that lets you view your blood sugar level.

The program is viewed on a receiver, a smartphone or an insulin pump. Some CGMs show your blood sugar reading at all times. They often include an alarm that goes off if your blood sugar goes up or down too quickly. Other CGMs require that you check your blood sugar by running the receiver over the sensor.

You may need to do this every few hours. Some people have to do it more often. With some CGMs , you still need to do finger-stick blood tests. These tests set the CGM. This is called calibration. The finger-stick blood tests also help keep the CGM readings precise. Check your device's user's guide to learn if you need to do finger-stick blood tests, and if so, how often.

Wine might make some CGM readings less precise. Some medicines also can have an effect on the readings, especially when used with older CGMs. Medicines that may affect blood sugar readings include:. Readings on newer CGMs don't seem to be affected by standard doses of acetaminophen — up to 1, milligrams for an adult.

Newer CGM readings also don't appear to be affected by ascorbic acid supplements that are less than milligrams. If you need to take medicines that may affect the accuracy of the readings, check the package insert that comes with the sensor. Or talk to your healthcare professional. You may be told to double-check your CGM results with a standard blood sugar meter.

Check with your healthcare professional about using a CGM if you are:. These conditions may affect the blood sugar readings from a CGM. Ask your healthcare team what the right blood sugar range is for you.

Your healthcare professional works with you to set target blood-sugar test results based on factors that include:. The American Diabetes Association ADA tends to recommend the following target blood sugar levels. These targets are for most of the healthy people with diabetes who take medicines:.

But the ADA notes that these goals often vary. Your goals depend on your age and your health. Tell your healthcare professional if your blood sugar is often higher or lower than your target range. A blood sugar meter is used to test blood sugar. The meter measures the amount of sugar in a small sample of blood.

Most often, the blood comes from the side of the fingertip. Then the blood is placed on a disposable test strip. With certain CGMs , you still may need a blood sugar meter to set your CGM device daily. Your healthcare professional or a certified diabetes care and education specialist can recommend a CGM device for you.

They also can help you learn how to use your meter. Follow the instructions that come with your blood sugar meter. In general, here's how the process works:. Some meters can test blood taken from another body part such as the forearm or palm.

But these readings may not be as accurate as readings from the fingertips, especially after a meal or during exercise. Blood sugar levels change more often at these times. Using a body part other than the fingertips is not recommended when you set a CGM. That process also is called calibrating.

Talk with your healthcare professional about how often you need to record your blood sugar results. The readings given by many devices can be sent to a computer or smart device.

Bring your record of results with you to checkups with your healthcare professional. Ask what steps to take if you often get results that don't fall within the range of your target goals. There is a problem with information submitted for this request.
