Controlling blood sugar levels has been an age-old marker of good health. And if you’re managing diabetes, it’s something you're regularly tracking to ensure you are in an optimal range. 

A1c tests measure the average blood sugar levels over a three-month period. A normal range is considered to be below 5.7%, with prediabetes between 5.7% to 6.4%.
