Three months ago I was diagnosed as prediabetic with a Haemoglobin A1c value of 45. I changed my diet significantly and here we are (just tested) three months later with a value of 42. My understanding is that this value represents the "average" level over a three month period. If it was 47 three months ago and now 42 am I right to assume that the current level is circa 37 - (average of 47 and 37 is 42). I know this may be over simplistic but I'd like to think I'm currently well below the 42 level?
