When I take my blood sugar readings, I take them in both hands and use the same finger on both hands. My left hand is always 10 points higher. I just took it. My left hand said 124 on my ring finger and my right hand said 114 on my ring finger. Why is this?
Even if you take two different finger of the same hand it might differ.there will be difference in finger & venous blood taken from fore arm. Concentration of blood & blood sugar may vary in capillary blood. It is not abnormal.
