After getting a BG reading of 58, I did a little searching on here to see if I should be concerned. Another poster (I didn’t bookmark it and I couldn’t find it when I searched again, so I hope he will chime in here) said that he always tested twice because he has Reynaud’s and thought that might affect his first reading, i.e., that the blood closer to the surface of his extremities might register lower BG.
While I don’t have Reynaud’s, my fingers do get very cold during my daily fasting window, so I thought I would conduct a mini-experiment to see if I had the same results. I waited an hour, and then re-took my BG. It was down to 56. I immediately took it again - 64. Again - 67. Again - 69. Again - 70. Again - 69. I did not get a consistent reading until the fourth try, and they were each taken within seconds of each other.
My VERY unscientific conclusion is that there could be a correlation between “first blood” taken from the extremities and lower BG readings, and that if you take blood that has been circulating, the reading may be higher.
Anyone else have this experience?
