Can a glucose tolerance test give invalid results?

I had gestational diabetes and at my 9 week postpartum 2 hr tolerance test I got 86 fasting, 185 at one hour and 225 at two hours. They refurred me to an endo. I have begun testing my sugars again and they are all within normal range even after eating McDonalds, sugary foods, etc. They run from 85-120. I was having my period during the time the test was done, as well as dieting (no carb loading three days before), and the test wasn’t done until 2:30 pm after only 8 hours of fasting. Could any of these factors have effected the test results? If not, do I have diabetes even though all my readings are within normal range? What should I do? Thanks!

    Dear, Fasting and post prandial blood sugar levels are done after 8-10 hours of fasting. Carbohydrate restricted diet do improve blood sugar levels. This type of diabetes is generally curable. The blood sugar levels will improve steadily without diet control. Take care.
