Why is the blood sugar of different fingers different?

Blood sugar testing, an important part of modern human health management, has gained increasing attention. I wonder if you’ve ever experienced a situation where blood sugar can be tested with different fingers. What the hell is going on?First, we need to understand that blood sugar means glucose content in blood. When we tested it with a blood glucose instrument, we actually measured glucose concentrations in a small drop of blood at the tip of the finger. The vascular and neurological distribution of different fingers is not entirely consistent, which affects the blood circulation and blood pressure at the fingertips, leading to a slight error in blood sugar values.Specifically, the following are the main reasons for the difference in blood sugar in the fingers:(1) Differing blood: If, in measuring blood sugar, different blood levels are extracted from the right or the right two fingers, the concentration of blood sugar will vary, so the values measured will vary.(2) Differences in the quality of test strips: The quality of test strips on the market is uneven and the use of different brands or batches of test strips may also affect the detection of blood sugar.(3) Test Paper Reaction Time: Some of the pieces of paper are sensitive to blood and produce quick results while others are slow to react. This difference in response time may also lead to differences in blood sugar values.(4) Uneven use of glucose in human tissue: If we use a hand more frequently in our daily lives, the use of glucose in this hand is likely to be higher, thus affecting the detection of blood sugar.It is worth noting that although the blood sugar values measured in different fingers vary, this difference is usually within normal range. Generally, the difference in blood sugar values between fingers is more common within 1 mmol/L.Therefore, in conducting blood sugar tests, we do not have to be too obscurantized in each of these values. It is more important to maintain regular testing habits and to focus on overall trends in blood sugar values. At the same time, regular brands and qualified blood sugar units and test notes are selected to ensure the accuracy of the results.
