OGTT is advised to individuals at high risk of developing diabetes or those with impaired sugar levels. If one is diagnosed to have pre-diabetes, it is important to have OGTT repeated at 12 months initially; then as indicated by the results.
A oral glucose tolerance test (OGTT) requires the patient to fast for eight hours prior to the blood draw.
Scientists created a working guitar the size of a red blood cell to illustrate the possible uses of nanotechnology. The glucose tolerance test is a blood test that is used to check blood glucose levels in order to screen for either gestational or type 2 diabetes. To prepare for blood glucose testing, the patient should maintain a normal diet and daily schedule for a week or so before the test. How the test is administered depends on whether a person is being tested for type 2 diabetes or gestational diabetes. In order to interpret the glucose tolerance test results, blood test results are compared to levels that are considered within normal rangel.
When the glucose tolerance test results show numbers higher than the average, it may be an indicator of diabetes, requiring further diagnostic testing. 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. Ask MetaFilter is a question and answer site that covers nearly any question on earth, where members help each other solve problems. OGTT is used as a confirmatory test to diagnose diabetes & can indicate presence of pre-diabetes (insulin resistance). The test is done after at least 3 days of unrestricted diet & normal physical activity. The test is never done during any illness because blood sugar levels may fluctuate due to the underlying infection, medicines or illness.
The person is instructed to fast for 10-16 hours during which drinking plain water is permitted. 75 grams glucose is dissolved in 250 – 300 ml of water & it should be drunk by the person over the course of about 5 minutes.
She has done her post graduation from Pune University and she is currently pursuing her PhD in area of Diabetes Prevention.
Testing for type 2 diabetes involves drawing blood once, two hours after the patient drinks a sugary drink containing a measured amount of glucose. Too bad the test was so expensive though! A friend of mine was pregnant a little while ago (she actually just had the baby a few weeks ago) and I remember when she did this test. My cat has diabetes (poor kitty) and after he was diagnosed the doctor had me drop him off for a glucose tolerance test. They kept him all day long and tested his glucose levels every hour or so.
How exciting! My understanding is that the glucose test is standard care for OBs - not so much midwives. 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.
She works with Diabetes Unit, KEM Hospital (Pune), Just for Hearts (Pune), Moraya Multispeciality Hospital & Healing Hands Clinic (Chinchwad) etc. When testing for gestational diabetes, which is the type of diabetes that can occur during pregnancy, blood is drawn at least once, and may be drawn several times over a period of hours after the glucose solution has been ingested. These factors must also be taken into account when interpreting the test results, since they may lead to abnormal levels even though there is no medical problem present. I felt like you did; I didn't like the idea of drinking all that sugar just to see if I had a problem with sugar! Is this test really necessary if there aren't any other indications of gestational diabetes? 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. These values may differ somewhat with different doctors or laboratories, but are generally considered good average results. Results above the normal levels may also indicate other illnesses besides diabetes, also requiring further diagnostic testing and a thorough review of the patient's history.
The test must have been accurate, because he's doing very well on the insulin. However, I hope he doesn't need another test like this anytime soon. 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.
If the glucose tolerance test results show a blood glucose level out of line with acceptable levels, it indicates the possibility of diabetes or other health problems. Instead of the glucose tolerance test, a fasting blood draw can give you some helpful information. That's what my doc recommended as an alternative.
But like I said, the test is standard, so it's something for you and our wife to discuss with your caregiver.
