Fasting means that the person taking the test hasn't eaten for at least 8 hours before the test was taken. And having a glucose in the 40s would almost certainly cause symptoms like shaking, weakness, and confusion, unless the person had hypoglycemia unawareness. Do you mean that when these tests are administered, the subject is given an hourly dose of glucose?
The test works by giving a single dose of glucose to the subject, then measuring the subject's blood glucose levels at fixed time intervals after (1, 2, 3 hours). So, is it the case that an "ordinary" person fasting according to this schedule would not have glucose as low as this test result indicates?
For an insulin-dependent diabetic, you'd see these results if you took too much insulin at mealtime, thus depressing your blood-glucose levels an hour or two after eating. Just because the one dose of glucose given for the test sort of mimics the person eating a meal containing carbohydrate. I would only expect to see this in someone with diabetes who took too much insulin just before the meal (or glucose dose), like chinston says. The GTT result that you posted would indicate to me an excessive production of insulin by the pancreas post 100 or 75 mg glucose challenge.


Hypothetically, if a person wondered about this, would it be useful to ask the doctor about getting a glucometer and track this for little while. The most important thing would be to then bring those records and logs to your doctor to have them corrently interpreted -- I'm not sure if a GP would be all enthusiastic about that, as it's labour-intensive. This is supposed to be a common issue with people who have autoimmune issues and I've got several of them, all related. I had glucose tolerance about 20 years ago and got really shocky so they discontinued the test after about 3 hours if I remember that right.

Generally 1 hour after the dose, the body might still be processing the glucose so it would show up in the blood (which is why the normal range is higher then), but by 2 or 3 hours the body will have returned to fasting levels.
The values at 1, 2, and 3 hours are the blood glucose level at each time point following a challenge with glucose. Or maybe in someone with diabetes who takes an insulin secretagogue like Glyburide, which can cause hypoglycemia. Maybe they'd send you to an endocrinologist who'd be willing, if the results seemed really abnormal.
In other words the person has been given a set amount of sugar orally and the blood levels are checked at the time intervals.
They'd still probably want to do the OGTT, and maybe test your HbA1c before foisting you off on a specialist, because people's home meters and logs can be inaccurate. Some people do swear there is such a thing as reactive hypoglycemia in people who don't have diabetes, where they get low blood sugar after eating.
