Self-monitoring of blood glucose levels is an important daily management measure for people with diabetes. The correct measurement method not only ensures the accuracy of the data, but also reduces the discomfort caused by long-term needle pricking. In addition, there are 8 details that need to be known before measuring blood sugar to help patients better understand their blood sugar status.
Blood sugar is measured
Which finger is more accurate?
In fact, the results of measuring blood sugar on any finger are consistent.
When performing a blood glucose test, the ring, middle, or little fingers are often recommended because these fingers have fewer nerve endings and are less painful. Among them, the ring finger has a wider distribution of capillaries, a richer blood supply, and easier blood extraction.
In addition, blood is collected on the side of the finger, because the peripheral nerves are concentrated in the middle of the front of the fingertip and less on the sides, so the blood is collected at this location and the pain is less.
Before measuring blood sugar
These 8 details should be known in advance
Alternate fingers:
To avoid pain and injury caused by repeated punctures on the same finger, it is recommended to alternate the use of different fingers. You can take turns using your fingers in a certain order, such as starting with the ring finger of one hand, then the middle finger, the little finger, and then back to the ring finger of the other hand.
Clean your fingers:
Before measuring blood glucose, you need to clean your fingers to ensure the accuracy of the measurement. Hands can be washed with warm water and soap, then dried with a clean paper towel or cotton ball.
Warm Fingers:
In cold environments, blood circulation to the fingers may slow down, resulting in inaccurate blood glucose measurements. Therefore, before measuring your blood sugar, you can try to put your hands in a warm place, such as a warm water bag, to promote blood circulation.
Avoid pinching your fingers:
When measuring blood glucose, you should press your finger gently and avoid squeezing too hard. Squeezing too hard may cause tissue fluid to mix into the bloodstream, which can affect the accuracy of the measurement.
Choosing the right lancing pen:
The size and depth of the needle of the lancing pen can affect the effectiveness and pain of the blood collection. It is usually recommended to use a needle that is appropriate for the thickness of your finger to ensure that the blood is collected smoothly and with less pain.
Proper use of a blood glucose meter:
When measuring blood glucose, you should follow the instructions for use of the blood glucose meter. Make sure your meter is clean and calibrated and avoid using expired test strips.
Avoid eating too much on an empty stomach or eating too much:
Before measuring blood glucose, you should avoid excessive fasting or overeating, which will affect the accuracy of blood glucose measurement results.
Watch out for drug effects:
Certain medications may affect blood sugar levels, such as hormones, antibiotics, etc. Before measuring blood glucose, the intake of these drugs should be considered and measured under the guidance of a doctor.
