Hand Hygiene Impact: Should You Wash Your Hands Before Testing Blood Sugar?

Accurate blood glucose monitoring is essential for effective diabetes management. However, several factors can lead to "illusions" or inaccuracies in blood glucose test results. Understanding these factors can help ensure that you get the most accurate readings possible. Here are some common issues that can cause discrepancies in blood glucose measurements:

1. Drugs:

   • Certain medications can interfere with blood glucose levels. For instance, some drugs may increase blood glucose by affecting insulin action, while others may decrease levels through various mechanisms. It's important to be aware of the potential effects of any medications you're taking and to discuss them with your healthcare provider.

2. Environmental Factors:

   • The performance of blood glucose meters can be affected by environmental conditions such as pH value, temperature, humidity, and altitude. Always check the manufacturer's guidelines for the ideal conditions under which to use your meter and store your test strips.

3. Operational Errors:

   • Correct use of the blood glucose meter and test strips is crucial for accurate results. Here are some key points to consider:
     • Test Paper: Ensure the test paper is not expired, the container is properly sealed, and the code on the test paper matches the code on the package.
     • Hand Hygiene: Wash your hands with soap and warm water if possible, or use wet wipes to clean the blood collection site. This helps to remove any substances that might interfere with the test.
     • Blood Collection: Allow the arm to hang down naturally to improve blood flow, then massage the site and use the appropriate lancing device to obtain a sufficient blood sample. Avoid squeezing the sample, as this can dilute the blood and affect the result.

4. Retesting and Consultation:

   • If you suspect that your test results are not accurate, it's a good idea to retest. If you continue to have concerns, consult with a healthcare professional or contact the manufacturer of your blood glucose meter for further assistance.

It's essential to remember that changes in your diabetes treatment plan should only be made after discussing with your healthcare provider. Do not make adjustments based on questionable test results without first seeking professional advice. Proper management of diabetes involves a comprehensive approach, including regular monitoring, medication, diet, exercise, and regular consultations with your healthcare team. By being vigilant about the factors that can influence blood glucose readings and addressing them appropriately, you can better manage your diabetes and maintain optimal health.
