I can’t find my data - I think its on a different machine. I only regularly measure the variability between the Dex and the fingerstick. Dex works as a nice tie breaker if your super concerned about it. Remember that this difference in readings in more significant below BG = 100 than it is above 100.
Where I live, medical protocol says that the ambulance can take you, against your will, to the hospital if BG < 79. So, running at a perfect 83 may put you at risk of ambulance transport (although, I doubt that they would do this unless you were unconscious). How does meter inaccuracy affect their determination of ‘driving with low blood sugar?’ Could they suspend your license if the medics read a 79? Actual range means BG could be low or could be perfect. ??? Not to become a diabetes lawyer, but its a curious situation.
