What is the ideal diet to consume before doing a Post Prandial Blood Glucose test in a non-diabetic and in a known diabetic?

What are you trying to discover or demonstrate? Both could eat a steak and green salad with olive oil dressing and neither should show much difference between before and after meal blood sugar levels. But if both parties ate sticky toffee pudding and a jam doughnut, the diabetic's sugar reading would shoot up very high and probably only come down very slowly, after many hours, and may require medication, whereas the non-diabetic's may go up a bit, initially, but would return to normal, probably within an hour.

Basically I want to know what the diet should be before going for such a Test? Are there any laid down guidelines by any Diabetes Organization in UK or America?

I'm confused as to why you should be "going for" such a test. A post-prandial, i.e.. after meal, test, merely tells you how you have reacted to a particular meal and only makes sense when compared with the pre-prandial, or before meal, test.
It is more usual for doctors to ask you to have a fasting test or a glucose tolerance test. In both cases, you should not eat for 12(?) hours before the test. A glucose tolerance test reveals your reaction to a measured and standard amount of sugar and is carried out in a resting situation and, therefore the results are meaningful and comparable with recognised standards. Any normal meal won't do this. A normal meal's effect on your sugar levels will be influenced by exercise and fat content of the meal, as well as the sugar it contains.

for GTT, you eat at least 150g of carb for 3-4 days before, fast 12 hrs before test [is this what you want]
