Common Questions and Answers about Glucose tolerance test fasting level

Avatar n tn I had a glucose tolerance test and an insulin fasting (drinking the glucose drink) blood test done. I have seen my results but have not had them interpreted for me. My glucose fasting results came back within normal range but my insulin fasting results came back out of range for the 0,1, & 2 hour results. They were much higher than the normal ranges. Does this mean I have insulin resistance?
Avatar f tn I would recommend a OGTT (oral glucose tolerance test). My glucose was normal on fasting but abnormal two hours after drinking glucose. My fasting insulin was high and even higher two hours. (I would recommended insulin to be tested as well). In my case too much sugar in my diet lead to insulin resistance but hyperthyroidism caused impaired glucose tolerance.
Avatar n tn I have been seeing an endocrinologist because I am constantly having low blood sugar readings and have had a high fasting blood glucose test of 8.3. My endocrinologist feels this may be due to my dysautonomia. She thought maybe reactive hypoglycemia because I am having low fasting glucose levels as well as high. I went for a 2hr OGTT today and I am feeling horrible after the test. My baseline was 4.8 @ 8:55 Given 75g of glucose to drink At 4.3 @ 9:25 At 4.8 @ 9:55 At 6.2 @ 10:25 At 6.
Avatar n tn I'm a 53 year old woman who just had a 3 hour glucose tolerance test, here are my results: Fasting - 106 1 hour - 210 2 hour - 230 3 hour - 167 I'm not sure if these results mean I'm a pre-diabetic or diabetic. Thank you for your help in advance.
Avatar n tn I just had my insulin tested this past October - December. This first test was done as part of a 2-hour glucose tolerance test. My lab report shows normal insulin to be 3 - 28 micro IU/ml. My doctor had me come back in for re-test and did not require fasting. So, I don't believe the normal 3 - 28 range is necessarily fasting. I would LOVE to have an insulin level of 3.0. On my first test my insulin was a whopping 151. My re-test in December showed my level was 17.
Avatar n tn "i had a blood sugar test (the finger ***** one) and my level was "perfect"." If you had soap or alcohol residue on your finger the test results would be imperfect. If the meter was old and mishandled, uncalibrated, test strips expired the test would results would be imperfect. The OGTT is one way to help determine blood glucose levels. Be sure to fast 8-10 hours prior. No food or colored liquids during this period. Don't cheat. Just a little bit skewers the results.
Avatar n tn How much the sugar varies from before meal to after meal seems to be the issue here. The glucose tolerance test is the correct test to see how your body reacts to high levels of carbohydrates. It does sound to me as if you perhaps vary more than is ideal, for a low of 57 or high of 256 is something that even diabetics try to avoid.
Avatar f tn Hi, Is this 140 a fasting level? If it is a fasting level it is not normal. Normal fasting should be lower than 95, and ideally even in the 80s. Are you overweight or any other health issues? Family history of diabetes? I would strongly recommend that you visit your doctor and tell him or her your results. They should do some further investigation. Hba1c and glucose testing. If you have a home glucose meter, please do some more testing.
Avatar n tn I was just informed I needed to do a 3 hour glucose tolerance test because my one hour was "very high" at 191. I have a calibrated glucometer and I've done finger/arm tests throughout the day and have not had anything remotely abnormal. I had a fasting blood sugar level of 93 first thing in the AM and all my levels after eating were 135 or below. Could the 191 have been error?
Avatar n tn Now a dx of Diabetic Type II has been made based on a 3-hour Glucose Tolerance Test. Told that Dr a year ago there was more going on that merely Thyroid and Perimenopause. Was I ever right! Turns out that in an overview of regular blood tests, I don't indicate any problems. Because of that, he turly believed nothing would be found abnormal. Fasting blood glucose is still in the Normal range despite it takes 3 hours on the GTT for my glucose to get back to a normal level.
Avatar m tn I can say that the fasting test shows your glucose level at one moment in time. Your A1c tells you what your average glucose levels were over the past 3 months so since that was normal, that's a good sign. There are many reasons that blood sugar could be high and stress is one of them. Also certain medications and supplements such as niacin and steroids can raise your blood sugar. I'm not in the medical field; this is information I've learned in doing my own research.
Avatar n tn My fest glucose level was at 170, and I did the 3 hours glucose tolerance test. The results were 290 after the first hour, 248 after 2, and 210 after 3. Also, there was glucose in my urine. After that, I did another blood/urine test (without festing at all), and no glucose or ketones were found in my urine, and my cholesterol was 169, which I think is perfect.
Avatar f tn With most fasting glucose tolerance test I think it was 10 hours only. Here when you have a fasting test the won't accept anything over 12 hours.
Avatar n tn The range of 70-126 is considered normal before eating a meal, or as a fasting glucose level. So although the one test at slightly above 200 does seem suspect, one test alone is probably not something your doctor would base a diagnosis on. Most doctors will do a fasting glucose reading, perhaps a glucose tolerance test, or perhaps a hemoglobin a1c test, which would show the average glucose level in your body during a 3-month period.
Avatar m tn Hello, I am a 46-year-old white male, 152 lbs., 6' 0". I exercise and lift weights daily. All of my other health indicators are excelent. My endocrinologist has just diagnosed me as being pre-diabetic based on results of the oral glucose tolerance test. However, I've been unable to find online where a high one-hour blood sugar value has been the basis for diagnosis. I know that the OGTT two-hour level that is the cutoff for diabetes diagnosis is 200.
Avatar m tn For the most definitive diagnosis, more than one value is used. A person can be diagnosed by using fasting plasma glucose level, the HGB A1C, and an oral glucose tolerance test. The guidelines for a diagnosis of pre-diabetes are the following: AIC: 5.7-6.4 Fasting Glucose: 100-125 Oral GTT: 140-199 Therefore, if you compare your numbers to the diagnostic guidelines, a diagnosis would be iffy. It's not clear enough, IMO to say either way.
Avatar n tn Besides blood work, one of the tools that your physician should order is a glucose tolerance test. Diabetes is defined as having a fasting plasma blood glucose level of 126 mg/dl or greater on two separate occasions. In general, people who have a fasting plasma blood glucose in the 100-125 mg/dl range are defined as having impaired fasting glucose.

This test is given to see how well your body sheds excess glucose after 1, 2 and 3 hours of ingesting the liquid. 3.) RGT [Random Glucose Test] - Tested at any given time. Several may be done throughout the day. Levels that vary widely indicates a problem.
