AT&T issues?

I was wondering if someone might be able to provide a bit more detail regarding AT&T? I am actually scheduled to go in for some glucose testing at the Mayo Clinic, and I was curious if anyone here has been through the process before. I suppose I’m wondering how long the whole thing typically takes, how many times they need to draw blood, and whether I should follow a specific diet or fast beforehand...??? thanks...

The Oral Glucose Tolerance Test (OGTT) involves blood draws from a vein
Patients need to stick to a standard diet for at least three days, hitting about 200-250 grams of carbs daily. You’ve got to maintain your usual activity levels—don't go changing your lifestyle suddenly. Avoid any medications that mess with glucose or sugar metabolism. Also, stay away from anything containing the pyrazolone group or Vitamin C, and skip any X-ray exposure at least 24 hours before the test. Usually, we start the procedure in the morning, somewhere between 7:00 and 8:00 AM.
For adults, we use a 75g glucose load dissolved in tea (without Vitamin C), while pregnant women get a 100g dose.
We measure serum glucose levels right before the dose, then again at the 30, 60, 90, and 120-minute marks. No smoking during the test, and you need to stay resting...
Besides the blood work, we can also check glucose levels in urine at fasting, 60 minutes, and 120 minutes after the dose.

The patient is required to maintain a standard diet for at least three days, consisting of approximately 200-250 grams of carbohydrates daily. One must remain physically active as usual, without any sudden lifestyle shifts. It is imperative to avoid medications that interfere with the metabolism of glucose or other sugars. Furthermore, one should refrain from taking any medications containing the pyrazolone group or Vitamin C, and avoid X-ray exposure, for at least 24 hours prior to the challenge. Typically, the testing process commences in the morning, between 7:00 and 8:00 AM.
For adults, the challenge involves 75 grams of glucose dissolved in tea devoid of Vitamin C, whereas pregnant women are administered 100 grams of glucose.
Glucose levels are measured in the venous serum both before the glucose load and at 30, 60, 90, and 120 minutes following administration. Smoking is strictly prohibited during the procedure, and the patient must remain at rest...
In addition to serum glucose, urinary glucose may also be assessed at specific intervals: while fasting, and again at 60 and 120 minutes after the glucose load.

As for my own experience, I was provided with absolutely no instructions prior to the actual AT&T procedure. I was simply told to arrive on an empty stomach, much like any other routine blood work. In the morning, I provided a urine sample followed by blood... then they handed me this rather tasteless glucose solution—I believe it was in a 200ml cup—and instructed me to return in two hours, noting that I shouldn't move around too much...

Thanks... I was actually wondering how this process works here in the States. In my experience, they only ever checked my blood sugar before meals and again two hours after eating, so I was curious about how these protocols differ out here...
