Just diagnosed as prediabetic. Fasting BG was 7.5 then 2 hours after glucose drink it was 11. That was a week ago. Bought a home meter and have been testing regularly, my fasting glucose has never been more than 5.8 or lower than 4.8 and 2 hours after meals is very similar always around 5.8 or less. Could the hospital have made such a mistake? or is it my meter? I do not suffer from any symptoms of diabetes yet.
