I ate half a bagel and then ran six miles before my blood draw. The instructions were to fast for 8 hours, but I only fasted for 6 hours. Do you think this will affect the result of the blood draw? My results came back as pre-diabetic. I am 5'7" tall, female, age 51, weight 135 lbs, very active. No risk factors other than my brother got the same diagnosis but he is very overweight.
