Common Mistakes in Checking Your Blood Sugar Level

Checking your blood sugar is a vital part of managing diabetes or prediabetes. However, even small errors in technique can lead to inaccurate readings, making it difficult to make informed decisions about your health. This article highlights 20 common mistakes people make when checking their blood sugar and provides tips for accurate results.

1. Using Expired Test Strips

Test strips have an expiration date for a reason. After that date, the chemicals degrade, leading to unreliable readings. Always check the expiration date before using a strip.

2. Storing Test Strips Improperly

Heat, humidity, and direct sunlight can damage test strips. Store them in their original container, tightly closed, in a cool, dry place.

3. Not Washing Your Hands

Residual dirt, oils, or food particles on your hands can contaminate the blood sample and skew the reading. Wash your hands thoroughly with soap and warm water before testing.

4. Not Drying Your Hands Completely

Water on your hands can dilute the blood sample, leading to a falsely low reading. Dry your hands completely before pricking your finger.

5. Using the Same Lancet Multiple Times

Each lancet is designed for a single use. Reusing lancets can dull the needle, causing pain and potentially increasing the risk of infection.

6. Pricking the Finger Too Deeply

Pricking too deeply can cause more pain and may not produce a sufficient blood drop. Follow the device instructions for proper finger placement and depth.

7. Not Getting a Sufficient Blood Drop

A small, rounded drop of blood is needed for an accurate reading. If the drop is too small, the meter may give an error message or a skewed result.

8. Smearing the Blood on the Test Strip

Allow the blood to be drawn into the test strip by capillary action. Smearing the blood can introduce errors in the reading.

9. Reading the Meter Too Quickly

Allow the meter to complete its analysis before recording the reading. Rushing the process can lead to inaccurate results.

10. Not Calibrating the Meter (If Required)

Some meters require periodic calibration to ensure accuracy. Follow the manufacturer’s instructions for calibration.

11. Using the Same Finger Frequently

Repeatedly pricking the same finger can lead to soreness and calluses, which can affect blood glucose levels. Rotate between different fingers.

12. Not Considering External Factors

Certain medications, stress, and even temperature can impact blood sugar readings. Be aware of these factors and note them when recording results.

13. Ignoring the Control Solution Test

The control solution test verifies the accuracy of your meter and test strips. Perform this test periodically as recommended by the manufacturer.

14. Not Recording Readings Properly

Maintain a log of your blood sugar readings, noting the date, time, meal, and any medications taken. This helps identify patterns and trends.

15. Not Seeking Professional Guidance

If you consistently get inaccurate or confusing readings, consult your healthcare provider or a certified diabetes educator.

16. Misunderstanding Meter Error Messages

Familiarize yourself with the error messages displayed by your meter and understand what they mean. Refer to the user manual for clarification.

17. Failing to Account for Altitude

High altitude can affect blood glucose levels. If you travel to a higher altitude, monitor your readings more closely.

18. Not Understanding the "Rule of 15" for Hypoglycemia

If your reading is low, follow the "Rule of 15": Consume 15 grams of carbohydrate, wait 15 minutes, and recheck your blood sugar.

19. Overlooking Potential Interference from Topical Medications

Some topical medications applied to the finger can interfere with the reading. Avoid testing on fingers recently treated with these medications.

20. Relying Solely on Blood Sugar Readings Without Considering Symptoms

Blood sugar readings are a guide, but they shouldn’t be the only factor in making decisions. Consider how you feel and any symptoms you are experiencing.

By being mindful of these common mistakes and following proper testing techniques, you can ensure more accurate blood sugar readings and better manage your health.
