Capillary Blood Glucose: Self-Monitoring

Capillary Blood Glucose

Capillary blood glucose is a method of monitoring blood glucose. A person living with diabetes can measure their own blood sugar (glycaemia) level using a blood glucose meter (glucose meter). Based on the results obtained, she can adjust or check the effect of her habits and treatment (diet, physical activity, insulin, medication, stress management, etc.)

Advantages:


The person living with diabetes may perceive self-monitoring as a constraint for several reasons: equipment to carry, injecting themselves sometimes several times a day, feeling of frustration or anxiety in the face of certain unexpected results. However, by understanding the benefits of self-monitoring, you realize that it is very useful for managing your diabetes.

Self-monitoring allows:

  • Check the impact of the different elements of the treatment on your blood sugar and make adjustments, if necessary.
  • Complete the information provided by glycated hemoglobin.
  • Identify, promptly treat and prevent hypoglycemia as well as hyperglycemia.
    To develop a sense of confidence, security and autonomy.

Measuring your blood sugar: Teaching and material


Meeting a healthcare professional as a first step would be a wise choice. After identifying your needs, he will suggest a blood glucose meter that you can get at a pharmacy, as well as any other equipment necessary for self-monitoring. Here is the equipment needed to measure your blood sugar: glucometer (device); lancets (needles); Lancing device (device where the needle is inserted); Reactive strips (where the drop of blood is placed). You will then learn how to properly measure your blood sugar:

  1. Take a soap, wash your hands with water and dry them well.
  2. Take a blood glucose meter and insert a test strip into it.
  3. Insert a new lancet into the lancing device*.
  4. Prick the tip of the finger (lateral part).fingers hand
  5. Gently squeeze fingertip as needed.
  6. Bring the blood into contact with the test strip.blood contact the strip test
  7. Wait a few seconds (time varies depending on the reader).
  8. Read and write the result in a notebook, an application or save it in the blood glucose meter.
  9. Discard the strip and the lancet in a container for biomedical waste (available in pharmacies). *Use a new lancet each time you use it

Attention !


Avoid pricking the thumb and forefinger: this is called “the clamp”. Indeed, carrying out repeated capillary blood glucose tests can lead to a loss of sensitivity in the fingertips and make it more difficult to pick up objects. Similarly, favor the sides of the fingers and preserve the central part called “the pulp“.
