How to Check Blood Sugar at Home: A Guide to Meters, Test Strips & CGMs

Managing diabetes effectively often involves monitoring your blood sugar levels regularly. Fortunately, it's entirely possible to check your blood glucose at home. This guide will walk you through the various methods, including blood glucose meters, test strips, and Continuous Glucose Monitors (CGMs), and provide tips for accurate readings.

Why Home Blood Sugar Monitoring is Important

Checking your blood sugar at home empowers you to:

• Understand how food, exercise, and medications affect your blood glucose levels.
• Identify patterns and trends that can help you and your healthcare provider adjust your treatment plan.
• Recognize and respond to high (hyperglycemia) or low (hypoglycemia) blood sugar levels quickly.
• Improve overall diabetes management and reduce the risk of complications.

Blood Glucose Meters: The Traditional Method

A blood glucose meter is a small, portable device used to measure the amount of glucose in your blood. Here's how to use one:

1. Gather Supplies: You'll need a blood glucose meter, test strips specific to your meter, a lancing device with lancets, and alcohol wipes (or soap and water).
2. Wash and Dry Your Hands: Clean hands are essential for preventing inaccurate readings. Wash with soap and water and dry thoroughly.
3. Prepare the Lancing Device: Insert a new lancet into the lancing device and adjust the depth setting to a comfortable level.
4. Insert the Test Strip: Insert a test strip into the blood glucose meter. Make sure it's the correct strip for your meter. The meter will usually turn on automatically.
5. Prick Your Finger: Use the lancing device to prick the side of your fingertip. The side of the finger is often less sensitive.
6. Apply Blood to the Test Strip: Gently squeeze your finger to obtain a small drop of blood. Touch the blood to the designated area on the test strip. The meter will start analyzing the sample.
7. Wait for the Reading: The blood glucose meter will display your blood sugar reading within seconds.
8. Record the Result: Record your reading in a logbook, app, or other tracking system. Note the date, time, and any relevant information (e.g., meal eaten, exercise).
9. Dispose of the Lancet Properly: Safely discard the used lancet in a sharps container or other puncture-proof container.

Choosing the Right Blood Glucose Meter

Numerous blood glucose meters are available on the market. Consider these factors when choosing one:

• Accuracy: Look for meters that meet international accuracy standards.
• Ease of Use: Choose a meter with a clear display, easy-to-handle test strips, and simple operation.
• Features: Some meters offer features like data storage, Bluetooth connectivity, and reminders.
• Cost: Consider the cost of the meter itself and the ongoing cost of test strips.
• Insurance Coverage: Check if your insurance plan covers certain blood glucose meters and test strips.
• Size: Determine if you prefer a small, portable meter or a larger, more feature-rich one.

Test Strips: Understanding Their Importance

Test strips are essential for using a blood glucose meter. Each test strip contains chemicals that react with the glucose in your blood to produce an electrical signal, which the meter interprets as your blood sugar level. It's crucial to:

• Use the Correct Test Strips: Always use test strips specifically designed for your blood glucose meter. Using the wrong strips can lead to inaccurate readings.
• Check the Expiration Date: Expired test strips can produce unreliable results.
• Store Strips Properly: Store test strips in a cool, dry place, away from direct sunlight and moisture. Keep them in their original container with the lid tightly closed.
• Handle Strips Carefully: Avoid touching the reaction area of the test strip with your fingers.

Continuous Glucose Monitors (CGMs): A Technological Leap

A Continuous Glucose Monitor (CGM) is a device that continuously tracks your blood glucose levels throughout the day and night. Instead of pricking your finger multiple times a day, a CGM uses a small sensor inserted under the skin to measure glucose in the interstitial fluid (the fluid surrounding your cells).

How CGMs Work

1. Sensor Insertion: A small sensor is inserted under the skin, typically on the abdomen or upper arm.
2. Transmitter Attachment: A transmitter is attached to the sensor. The transmitter sends blood glucose readings wirelessly to a receiver or a compatible smartphone.
3. Real-Time Readings: The CGM displays your blood sugar level in real-time, along with trends and alerts for high and low glucose levels.
4. Data Tracking: The CGM stores your blood glucose data, allowing you to track your levels over time metformin and blood sugar and identify patterns.

Benefits of CGMs

• Continuous Monitoring: Provides a comprehensive view of your blood sugar levels, including overnight readings and post-meal spikes.
• Real-Time Alerts: Warns you when your blood sugar is too high or too low, allowing you to take action quickly.
• Improved Glycemic Control: Helps you better manage your diabetes by providing insights into how food, exercise, and medications affect your blood glucose levels.
• Reduced Fingersticks: Eliminates the need for frequent fingersticks (some CGMs may require occasional fingerstick calibration).
• Data Sharing: Allows you to share your blood glucose data with your healthcare provider remotely.

Choosing a CGM

Different CGM systems are available, each with its own features and benefits. Consider these factors when choosing a CGM:

• Accuracy: Look for CGMs with a proven track record of accuracy.
• Ease of Use: Choose a CGM that is easy to apply, use, and interpret.
• Features: Consider features like alerts, trend arrows, data sharing, and integration with insulin pumps.
• Calibration Requirements: Some CGMs require fingerstick calibrations, while others do not.
• Cost: CGMs can be expensive, so check your insurance coverage and consider the ongoing cost of sensors and transmitters.

Understanding Blood Sugar Readings

Your target blood sugar range will depend on your individual circumstances and your healthcare provider's recommendations. However, general guidelines are:

• Before meals: 80-130 mg/dL
• 2 hours after the start of a meal: Less than 180 mg/dL

Consult with your healthcare provider to determine your specific blood sugar targets.

Factors That Can Affect Blood Sugar Readings

Several factors can influence your blood sugar readings, leading to inaccurate results. These include:

• Expired Test Strips: As mentioned above, expired test strips are inaccurate.
• Contaminated Hands: Food residue or other substances on your hands can affect the reading.
• Dehydration: Severe dehydration can falsely elevate your blood sugar.
• Illness: Infections and other illnesses can affect your blood sugar levels.
• Stress: Stress can increase your blood sugar.
• Medications: Certain medications, such as steroids, can raise blood sugar.
• Altitude: High altitude may impact blood glucose meter accuracy in some situations.
