How to Use a Blood Sugar Test Meter Accurately

Managing your blood sugar is a cornerstone of diabetes care. A blood sugar test meter is an essential tool, offering valuable insights into your glucose levels throughout the day. However, an inaccurate reading can lead to unnecessary worry or improper medication adjustments. This article guides you through the process of using a blood glucose meter accurately, covering everything from preparing your supplies to interpreting your results.

Why Accurate Blood Sugar Testing Matters

Reliable blood glucose monitoring helps you:

• Track how food, exercise, and medication affect your blood sugar levels.
• Identify patterns in your blood sugar readings.
• Make informed decisions about your diet and activities.
• Adjust your medication dosage correctly, as prescribed by your doctor.
• Detect hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar) early.
• Reduce the risk of long-term diabetes complications.

Preparing for Your Blood Sugar Test

Before you begin, gather the necessary supplies:

• Blood glucose meter: Make sure it's the correct model and programmed properly.
• Test strips: Check the expiration date and store them in a cool, dry place.
• Lancet device: This spring-loaded device holds the lancet.
• Lancets: These are the small, sterile needles used to prick your finger.
• Alcohol swab: To clean the finger you'll be pricking.
• Clean cotton ball or gauze: To stop the bleeding after the test.
• Sharps container: For safe disposal of used lancets and test strips.

Step-by-Step Guide to Accurate Blood Sugar Testing

Follow these steps carefully for the most reliable results:

1. Wash Your Hands Thoroughly: Use soap and warm water. Dry your hands completely, as moisture can affect the reading. Washing removes contaminants that might skew the result.

2. Prepare the Lancet Device: Insert a new lancet into the lancing device. Adjust the depth setting to a comfortable level. If you're unsure, start with a shallower setting and increase it if needed to obtain a sufficient blood sample.

3. Insert the Test Strip: Insert a new test strip into the blood glucose meter. Make sure the meter is turned on and displays the correct code, matching the one on the test strip vial (some newer meters automatically code).

4. Choose a Lancing Site: The sides of your fingertips are generally less sensitive than the pads. Rotate fingers to prevent soreness and callus buildup. Avoid pricking the tip of your finger or over a bone.

5. Cleanse the Lancing Site: Use an alcohol swab to clean the chosen fingertip. Allow the alcohol to dry completely before pricking, as residual alcohol can also affect the reading.

6. Prick Your Finger: Hold the lancing device firmly against the side of your fingertip and press the release button.

7. Milk the Blood Drop (Gently!): Gently squeeze or massage your finger near the puncture site to encourage a small drop of blood to form. Avoid excessive squeezing, as this can dilute the sample with tissue fluid and cause an inaccurate reading.

8. Apply Blood to the Test Strip: Hold the meter and test strip so the blood drop touches the designated area on the test strip. The meter will usually beep or display a symbol to indicate that enough blood has been applied.

9. Wait for the Result: The blood glucose meter will display your blood sugar reading within seconds.

10. Apply Pressure: Use a clean cotton ball or gauze pad to apply gentle pressure to the puncture site until the bleeding stops.

11. Dispose of Materials Properly: Safely dispose of the used lancet in a sharps container. Discard the used test strip. Factors Affecting Blood Sugar You Might Not Expect

12. Record Your Result: Log your blood sugar reading in a notebook, app, or the meter's memory. Note the time, date, meal, activity, and any medications you took.

    

Common Mistakes and How to Avoid Them

Even with careful technique, errors can occur. Here are some frequent mistakes and how to prevent them:

• Using Expired Test Strips: Expired strips can give inaccurate readings. Always check the expiration date.
• Incorrect Meter Coding: Ensure the meter code matches the code on the test strip vial (if your meter requires coding).
• Insufficient Blood Sample: Not enough blood can cause errors. If you don't get enough blood on the first try, use a new lancet and test strip.
• Contaminated Fingers: Food residue or lotion can affect the reading. Wash your hands thoroughly.
• Incorrect Storage of Supplies: Store test strips in their original vial, away from moisture and extreme temperatures.
• Damaged Test Strips: Check that the test strip is not damaged, folded or bent.

Understanding Your Blood Sugar Readings

Your blood sugar levels will vary throughout the day depending on factors like food intake, exercise, stress, and medication. Talk to your doctor or diabetes educator about your target range. In general, these are the recommended blood sugar targets for most adults with diabetes:

• Before a meal (preprandial): 80-130 mg/dL
• 1-2 hours after starting a meal (postprandial): Less than 180 mg/dL

However, individual targets may vary based on age, health conditions, and medication.

Troubleshooting Blood Sugar Meter Issues

If you encounter problems with your blood glucose meter, try these steps:

• Check the Batteries: Ensure the batteries are fresh and properly installed.
• Clean the Meter: Use a soft, dry cloth to clean the meter.
• Review the User Manual: Consult the manufacturer's instructions for troubleshooting tips.
• Contact the Manufacturer: If problems persist, contact the manufacturer's customer support.
• Have a Control Solution test Certain meters have a special solution to test functionality of the meter. This is not the same as testing your blood sugar.

Advanced Blood Glucose Monitoring Technologies

Beyond traditional blood sugar test meters, newer technologies offer continuous glucose monitoring (CGM). CGM systems use a sensor inserted under the skin to track glucose levels in real-time. This provides a more comprehensive view of blood sugar trends than fingerstick testing alone. While CGM systems require a prescription and may not be suitable for everyone, they can be a valuable tool for managing diabetes effectively.

The Importance of Regular Blood Sugar Monitoring

Regular blood glucose monitoring is a critical part of diabetes management. It helps you stay informed about your blood sugar levels and make informed decisions about your health. Work closely with your doctor or diabetes educator to develop a testing schedule that meets your individual needs. The insights you gain from accurate blood sugar testing can empower you to take control of your diabetes and live a healthier, more fulfilling life.
