The fasting blood sugars should be less than 110 mg/Dl and the PP should be less than 140mg/dl. HbA1c indicate the blood sugar control over a period of 3 months. It mainly depends upon the PP sugars. It means that if you have a very high sugars in the last 3 months, the HbA1c will be high. It should be less than 6.5.

There is no age wise specific reference range for glucose. WHO protocols says fasting sugar levels below 110 are normal, between 110-125 - impaired glucose tolerance, and > 126 - diabetes. Similarly for PP samples , < 140 is normal, 140-200 is impaired , > 200 is - diabetes . These tests must be repeated at least once, PLUS you must also have some clinical symptoms of diabetes. HBAic test indicates your average blood sugar levels for preceding three months.It is basically to assess whether your sugar levels were controlled during the preceding 3 months or not. Again, a Hbaic > 6.5 % is highly suggestive of diabetes.
