Managing your blood sugar levels is crucial, especially if you have diabetes or are at risk of developing it. A blood sugar monitor, also known as a glucose meter, is an indispensable tool for keeping track of these levels. But how do you use one correctly? This article will guide you through the process, explain different types of monitors, and help you understand the importance of regular monitoring.
Why Monitoring Your Blood Sugar Matters
Monitoring your blood glucose is not just a recommendation, but a necessity for many. Here's why:
- Diabetes Management: For those with type 1 or type 2 diabetes, regular blood sugar checks help manage their condition, adjust medication, and make informed dietary choices.
- Hypoglycemia and Hyperglycemia Prevention: Monitoring helps prevent dangerous spikes or drops in blood sugar levels, known as hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).
- Understanding Your Body: Consistent tracking of blood sugar can reveal patterns, identify how your body reacts to specific foods, and measure the impact of exercise and stress on glucose levels.
- Improved Health Outcomes: By understanding your blood sugar trends, you can work proactively with your healthcare team to prevent complications associated with unstable levels, including nerve damage, kidney disease, and heart problems.
| Condition | Blood Sugar Level (mg/dL) | Time of Measurement |
|---|---|---|
| Normal (Fasting) | 70-99 | Upon waking |
| Pre-diabetes (Fasting) | 100-125 | Upon waking |
| Diabetes (Fasting) | 126 or higher | Upon waking |
| Normal (2 Hours After Meal) | Less than 140 | Two hours after the start of the meal |
| Pre-diabetes (2 Hours After Meal) | 140-199 | Two hours after the start of the meal |
| Diabetes (2 Hours After Meal) | 200 or higher | Two hours after the start of the meal |
Note: Consult with your healthcare provider for personalized target ranges as these can vary. These are general guidelines.
Different Types of Blood Sugar Monitors
Before we dive into how to use a meter, it's essential to know the types available:
-
Standard Glucose Meters: These are the most common. They require a small blood sample obtained with a lancet and provide results on a digital display. They often come with test strips which react with the blood sample and allow the monitor to take a reading.
-
Continuous Glucose Monitors (CGMs): These devices are becoming increasingly popular. They involve a tiny sensor inserted under the skin, usually on the arm or abdomen. It takes readings regularly and reports them to a receiver or smartphone app. CGMs don't require fingersticks to take readings, are typically accurate, and have built-in alarms to notify you if your sugar levels are too low or high. CGMs are generally expensive but often more convenient for people who use insulin or who find frequent testing challenging.
-
Non-Invasive Glucose Monitors (Experimental): Researchers are working on non-invasive options that would measure blood glucose through the skin or by analyzing bodily fluids. As of yet, these options are not widely available.
For the purpose of this article, we will focus on using standard glucose meters because they are still the most common and most widely used option.
Step-by-Step Guide to Using a Standard Glucose Monitor
Using a glucose meter correctly is essential to ensure accuracy and avoid discomfort. Here’s a step-by-step guide:
-
Gather Your Supplies: Make sure you have:
- Your glucose meter
- Test strips (ensure they are not expired)
- A lancing device with a fresh lancet
- Alcohol swabs or cotton balls
- A logbook or app to record readings
- A sharps disposal container for used lancets
-
Wash Your Hands: Always start with clean, dry hands to prevent infections and avoid skewing results with food residues. Washing your hands in warm, soapy water is best. Dry them thoroughly to avoid any water interfering with the blood sample.
-
Prepare the Lancing Device: Insert a new lancet into your lancing device as per the device instructions. Adjust the depth setting for a comfortable but effective puncture.
- Use the lowest depth setting possible while ensuring enough blood is obtained. Deeper punctures are more painful and might lead to bruising or infection.
-
Prepare the Test Strip: Insert a test strip into your meter. Make sure it's firmly inserted. If the meter requires coding, ensure the code on the strip matches the code on the meter. Wait for your meter to signal that it is ready, usually via a visual cue.
-
Select a Lancing Site: Pick a suitable site for lancing. The sides of your fingertips are best as they have fewer nerve endings. Avoid the very tip and middle of the finger. Rotate your site to avoid callus build-up on frequently-used fingers. Avoid any areas where your skin might be broken or where you might have other wounds.
-
Cleanse Your Fingertip: Use an alcohol swab to cleanse the chosen fingertip. Let it air dry or use a sterile gauze pad. Ensure no alcohol remains on the site, as it might affect the reading.
-
Puncture Your Finger: Press the lancing device against the cleansed site and press the release button to pierce the skin.
- For those with limited hand dexterity, assistive devices or tools might make this step easier. If help is available, you could also have someone else do it.
-
Obtain a Blood Drop: Gently press or massage your finger from base to tip, which helps to form a small blood drop. Be gentle, as excessive squeezing may also distort results.
- Avoid milking or squeezing harshly as it can introduce tissue fluid, which can dilute your blood sample and cause inaccurate readings.
-
Apply Blood to the Test Strip: Touch the edge of the test strip to the blood drop, and allow the strip to absorb the required amount. Usually, the strip is designed to suck up a tiny drop by capillary action, and you don't need to smear the blood or apply a large drop. The meter will often audibly signal when the correct amount has been obtained.
-
Wait for the Results: Your meter will start to calculate the blood glucose level, and the result will be shown on the digital display. Wait for it to beep or indicate completion. This step can often take several seconds.
-
Record Your Results: Log the result, noting the time and any relevant contextual information such as recent food intake or exercise. Use a physical logbook, a notebook, or digital app to track data for future reference. Sharing information with healthcare providers during consultations can be extremely helpful.
-
Safely Dispose of Materials: Carefully discard the used lancet in the sharps container, which is typically puncture-resistant. Ensure that used materials do not accidentally wound yourself, your caregivers or others. Discard the used test strip according to its instructions.
Best Practices for Accurate Monitoring
To ensure accurate readings and effective management, consider these guidelines:
- Follow Meter Instructions: Every glucose meter comes with its own specific instructions. Read the user manual thoroughly and keep it handy. Manufacturers may provide instructional videos.
- Proper Storage: Ensure your test strips are stored at the recommended temperature and humidity, often a cool, dry place. Keep them in their original vial. Avoid storing them in a refrigerator as the humidity can impact readings. Test strips typically have expiration dates, after which they might not be accurate. Discard expired strips appropriately.
- Regular Calibration: Some meters require calibration by using a control solution. Check the manufacturer's instructions and your device for appropriate guidance. You may have to use the control solution to test your device if it has sat unused for a while, if you get readings that do not seem reasonable, or if you opened a new box of test strips.
- Consistent Testing Times: Testing at consistent times and under similar conditions can lead to more accurate insights. If directed by your doctor, testing before meals and two hours after meals, or before and after physical activity can help reveal meaningful patterns and how your body is affected.
- Consult your doctor: Talk to your healthcare provider about the best times to test and to get your glucose targets or guidelines for target range that you need to meet.
Troubleshooting Common Issues
If you run into problems, consider these quick solutions:
- Error messages: Check the meter's manual for specific error messages. Many meters have a help section or FAQ for troubleshooting common issues.
- Inaccurate results: If you suspect inaccurate results, repeat the process with a new test strip. If you still suspect errors, calibrate the monitor using a control solution or call your meter's support line. Also check to ensure that your test strips have not expired.
- Not enough blood: Ensure the lancing depth setting is correct and use a fresh lancet. Consider gently massaging your finger as mentioned earlier and allow the drop to fully develop. If problems persist, retest after washing and drying the area again.
The Role of Continuous Monitoring
For individuals who require constant monitoring, CGMs offer valuable benefits, including real-time insights and alarm alerts. These are more expensive but often worth it for improved health management. While not a complete replacement for glucose meters, CGMs offer additional data points, more frequent readings, and greater convenience for many. A CGM usually involves wearing a sensor inserted under the skin, often in the arm or abdomen, with a reader/receiver that tracks trends and notifies you if you are trending low or trending high. If a CGM seems right for you, consult with your doctor or healthcare provider to obtain a prescription.
