My pathology lab gave me a special diet that I had to follow for the three days prior to the test. It had an amount of carbs to eat and at what times during the day. I think (pg brain) that I then had to fast prior to the test (8hrs) maybe and drink water only. I went in as soon as the lab opened at 8am and they did bloods and urine sample, then I drank the drink then did two more bts at hourly intervals, while still fasting. The girls in the lab checked up on me often as to how I was feeling, as the combination of the drink, high carb, fasting does make for quite an unwell feeling.

Maybe ring your pathology lab as ask them for the procedures, cause that is what I did, and mine sent me the diet sheet.

Good luck and I hope this one comes back more positive than the last one.
