Managing diabetes effectively often involves regular blood sugar monitoring, which can be easily done at home with the right device. A blood sugar monitor, also known as a glucose meter, is an essential tool for individuals with diabetes to track their glucose levels, helping them make informed decisions about diet, exercise, and medication. This guide will walk you through everything you need to know before buying a home blood sugar monitor, helping you select a device that fits your specific needs and lifestyle.
Why Home Blood Glucose Monitoring is Essential:
- Immediate Feedback: Blood glucose levels can fluctuate rapidly due to various factors like food intake, physical activity, stress, and medications. Home monitoring provides immediate feedback, allowing individuals to identify patterns and manage their condition proactively.
- Personalized Management: The data from regular home monitoring helps create a tailored diabetes management plan. This data guides dietary choices, exercise routines, and medication adjustments in collaboration with healthcare professionals.
- Prevention of Complications: Keeping blood glucose levels within the target range reduces the risk of short-term and long-term complications of diabetes, such as hypoglycemia (low blood sugar), hyperglycemia (high blood sugar), and organ damage.
- Increased Awareness: Consistent monitoring empowers individuals to recognize how their body responds to different activities and foods, improving overall awareness of their health.
Key Factors to Consider When Choosing a Blood Sugar Monitor
Selecting the right blood sugar monitor involves careful evaluation of multiple factors, including device functionality, ease of use, and cost. Here are some of the key aspects to keep in mind:
-
Accuracy and Reliability:
- Quality Standards: Look for monitors that meet international standards such as ISO 15197, which mandates the accuracy of blood glucose testing systems.
- Clinical Data: Opt for devices that have peer-reviewed studies demonstrating their accuracy.

- Data Management: Choose a monitor that can download data easily to a computer or mobile device using Bluetooth or a USB connection for analysis and sharing with your healthcare provider.
- Meal Markers: Some meters allow users to mark tests as before or after a meal.
- Averaging: It is beneficial to have features for calculating averages of blood glucose readings, e.g. 7-day, 14-day, and 30-day averages.
- Alerts: Look for alarms that will notify you of potentially high or low readings.
-
Testing Strip Requirements:
- Sample Size: Opt for devices that require only a small blood sample, as larger samples may be more painful and time-consuming.
- Availability and Cost: Check the cost and availability of test strips as they are an ongoing expense that you will need to budget.
-
Cost:
- Initial Investment: The initial cost of the device may vary, so budget according to your needs.
- Ongoing Costs: Remember to factor in the long-term cost of test strips, lancets, and control solutions. Insurance providers may cover a portion of the cost of a blood sugar monitor.
Understanding the Types of Blood Sugar Monitors
There are several types of blood sugar monitors available, each with its specific characteristics. Understanding these differences is vital in choosing the device best suited to your needs:
-
Traditional Blood Glucose Meters:
- How They Work: Require a finger prick with a lancet to draw a small blood sample that's then placed on a test strip inserted into the meter. The meter measures the glucose level using an electrochemical reaction on the strip.
- Advantages: Affordable, accurate and suitable for most patients with diabetes.
- Disadvantages: Can be less convenient for frequent testing, may cause discomfort to some due to finger pricks.
-
Continuous Glucose Monitors (CGMs):
- How They Work: Use a small sensor inserted under the skin to continuously measure glucose levels in interstitial fluid. The data is transmitted wirelessly to a compatible device.
- Advantages: Provide real-time glucose readings and trends, alert for highs and lows. Does not require frequent finger pricks.
- Disadvantages: More expensive than traditional meters and may require an initial setup process. May not be suitable for all people with diabetes, and can be subject to small levels of variation in readings versus traditional fingerprick methods.
-
Flash Glucose Monitoring (FGM) Systems:
- How They Work: Use a sensor placed on the skin, which must be scanned by the handheld reader to obtain a reading. FGM systems are generally a good compromise between accuracy and convenience of use.
- Advantages: Does not require fingerpricks and provides an overview of glucose trends, though not as continuous as CGM.
- Disadvantages: Can be expensive and the sensor must be replaced every 10-14 days, and the sensor may not be covered under insurance plans in some regions.
| Monitor Type | Method | Advantages | Disadvantages |
|---|---|---|---|
| Traditional Glucose Meter | Finger Prick | Accurate, affordable | Inconvenient with frequent testing |
| Continuous Glucose Monitor | Subcutaneous Sensor | Real-time monitoring, alerts, no finger pricks | Expensive, initial setup may be complex, readings can be different to fingerprick method in some cases |
| Flash Glucose Monitor | Scan Sensor | No finger pricks, good overview of glucose levels, easy to use | Sensor replacements needed, reading only shown when scanned |

Diagnosed with type 1 diabetes in 1946 at the age of 12, Dr. Richard K. Bernstein never set out to be a doctor. Not only that but according to statistics from the American Diabetes blood sugar level type 2 diabetes Association, he should have been long dead by now. That he is very much alive and, in fact, in excellent health, can be attributed to two primary causes. The first is that he was originally trained as an engineer and attacked his disease as a problem to be solved and not a condition is blood sugar and glucose the same to be treated. The second is that he was fortunate enough to still be alive when the first blood glucose meters arrived on the scene. In 1969, after following ADA guidelines for more than twenty years, Dr. Bernstein had many of the debilitating complications of the disease. Sick and tired of being at the mercy of his disease, he obtained one of the early blood glucose meters and became the first diabetic ever to monitor his own blood sugars. Dr. Bernstein used himself as a guinea pig and began testing his blood glucose throughout the day, hoping to discover what made it go up and down. After considerable trial and error, not to mention research, he discovered that he could normalise his blood blood sugar level low in morning glucose through diet, exercise and medication—and that he could help others do the same. When the then-engineer Richard Bernstein tried to persuade the medical community that he had found the answer, the medical community roundly ignored him—even told him that it was impossible. So, in his mid-forties, he decided the leave his successful career in business and go to medical school. These facts combined with Dr. Bernstein’s sheer determination to solve the problem of diabetes led to his revolutionary method of blood glucose normalisation, which he demonstrates in the groundbreaking, perennial bestselling book, Diabetes Solution. Today, many thousands of patients and readers later, Dr. Bernstein continues to see and train patients, maintains a busy schedule that includes a monthly question-and-answer teleconference, and continues to refine his cutting edge program of blood glucose normalisation. He reaches more patients than he ever could have back when he first opened his practice—and slowly the standard of care has been changing to mirror his ideas.
