Modified Glucose Tolerance Test
When one takes a drug, such as heroin or alcohol, repeatedly, 'tolerance' develops because more of the drug is needed to give the same effect on the body/brain; e.g. Liver enzymes r stimulated to metabolize the drug faster and faster. There may be a strong genetic predisposition to addiction, some studies suggesting that 1 of 10 people will become dependent on alcohol or some ...Read more
A check for diabetes: The GTT is a way for us to see who is at highest risk of diabetes. It is recommended that everyone be screened during their pregnancy, usually around 24-28 weeks. We will give you a bottle of a very sugary drink. You have five minutes to drink it all! Then a hour later we do a blood test to see how you metabolized the sugar. If you are high risk you may need further testing or treatment. ...Read more
Yes: You actually need a glucose challenge test (gct) in pregnancy, which is a 1 hour screening test for gestational diabetes. If your screening test is abnormal then you need the glucose tolerance test (gtt), which is typically a 3 hour test. It is very important that all women are screened for gestational diabetes in their pregnancies. ...Read more
GTT at home: Glucose tolerance testing is done less frequently now a days. You can do your own home version geta home glucose testing kit. Do the 1st blood glucose after an overnight fast, have a very hearty breakfast and do a bl glucose 1 hour and 2 hrs after the breakfast. Your fasting bl glucose should be below 200 if above 200 you do not need to do the test, you have diabetes and the result will not cha. ...Read more
Screen for diabetes: A normal test can help you feel better that you don't have diabetes. An abnormal test can fall into two buckets - either borderline or frankly diabetic. The cutoffs for "abnormal" are different depending on why you had the test. This is a good thing to speak to the ordering physician about. ...Read more
Test: Hi. The most standardized test for diabetes, the Oral Glucose Tolerance Test generates data for fasting and a "postprandial" in response to a standard caloric challenge (75 grams of glucose) measured 2 hr after the glucose. Based on criteria for the fasting and 2 hour post-challenge glucoses, you are either normal, diabetic, or the gray zone in between, pre diabetes. Eat healthy diet & exercise! ...Read more
Relax: Just show up, drink the glucola and let them draw your blood. It is not a big deal. ...Read more

Fail first glucose tolerance test repeated with a fastied 3hour gluclose tolerance with 100mg oral. 1st hr normal 2nd and 3rd is above normal range?
Need more info: Please note that lab results need to be interpreted in the total clinical context and the doctor who ordered the tests is in the best position to do that. Actual values are needed for evaluation and related circumstances, e.g. Are you pregnant? What is your hb a1c level, do you have symptoms of diabetes? ...Read more
Not an approved test: Hi. You could conceivably weigh out 75 grams of glucose at home and use a finger stick blood glucose meter and do something very similar to a real, diagnostic Standard 2-Hour OGTT, and get a good sense for your glycemic status, but there is no test approved for home diagnosis. Serum glucose should be used (not whole capillary blood). If you want an OGTT, I surest you go get a real one. Good luck! ...Read more
No: Hi. No, no home OGTT tests are available. ...Read more

Probably diabetic: A level of 10.8 during the test is just below diagnostic for diabetes. You should do a hba1c, but you have, at the least, impaired glucose tolerance. You should be following a low concentrated sweets diet. If overweight, you need to lose weight. Exercise. You may also need medication based on other lab results. ...Read more
Blood draw: Finger stick glucoses aren't accurate enough for the test. ...Read more
Depends: It depends. If you are having the initial 1 hour glucose challenge test performed at 24-28 weeks, you will have bloodwork drawn one hour after drinking the glucola. If you failed the 1 hour sugar test, a 3 hour sugar test would be performed and blood would be drawn before you drink the glucola and at 1, 2 and 3 hours later. ...Read more

My glucose tolerance test results are: fasting: 100 mg/dl, 1hr: 148mg/dl, 2hr: 128 mg/dl. My hbc1a : 5.7. I am concerned....Am I prediabetes?
Probably not: The fasting glucose of 100 and hba1c of 5.7 are borderline high, the other tests are normal. Diabetes is defined by fasting glucose above 125 or post prandial glucose above 200, or hba1c above 6.5%. People with prediabetes will typically also have triglycerides above 150, HDL cholesterol under 50 in a female, hypertension, and obesity. ...Read more
Glucose tolerance test: I passed but 1hr-173; 2hr-167; 3hr-103. I walked during last hour. Would walking make me pass when I should have failed?
Even though you did not follow the protocol, given the other results, you are not likely to have failed the test had you stayed put as required. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more
