Welcome to HealthCareMagic,
If only two samples(in the beginning & very end) have been taken, then test is not GTT
. It is fasting and pp blood sugar test only. Without report it is not possible to diagnose gestational diabetic or non-diabetic. Glucose
taken for GTT can cause light headedness and give you nauseating feeling. You can upload your reports, as soon as you get it, for further discussion.
Hope you found my response to your query informative and helpful.
With good wishes,
Dr.Chandra Shekhar Sharma
