Delecate Dove, I am having my second one on Monday. I didn't fail the first one, but the results were a little higher than normal (7.7 and the cut off is 7.8).

This is the run down I got from the pathologist;

-Eat a carb loaded diet for several days - heaps of cereal, bread, pasta etc
-Fast from 9pm the night before the test - water is allowed after this time
-Take a first morning urine sample to take with you - this needs to be tested before the test commences
-First lot of bloods will be taken
-Drink the glucose drink
-After 1hr another set of bloods are taken
-At the end of the 2nd hr another set of bloods are taken.

HTH
