Get to know about the blood glucose tolerance test.
What's blood glucose tolerance test? How can I read and interpret the results?Which results may make me worry?These are true worries for you as a diabetic. You'll have the answers you need if you read the following. Now, first of all you must understand that this test is also called blood sugar tolerance test or just glucose tolerance test. It's a test you perform to get to know how your body breaks down your blood sugar (glucose). Before you perform this test, you'll be advised not to eat or drink anything at least for 8 hours. Then, you'll measure fasting blood glucose level and record the result. After that you will drink a sweet drink and after two hours you'll measure again your blood sugar level and record the result. How can you read and interpret the results? The normal results would be as following: The fasting blood glucose level 70 to 100 mg/dl, meanwhile your blood sugar level after two hours should be less than 140 mg/dl. If your blood glucose level would be between 140 and 200 mg/dl, then you may have pre-diabetes ( or impaired blood glucose level). If you come out with results more than 200 mg/dl, then you may consider the possibility to have diabetes. But to confirm this, you must repeat the test. On the other hand, high levels of blood glucose may derive from other health problems. For this you must check with your physician. The chart below will give you a clearer idea on oral blood glucose tolerance test. |
