Prediabetes or
diabetes is normally diagnosed as a part of routine check up. Doctors recommend checking the blood glucose level at least once in a year after a person reaches the age of forty five. There are two types of
prediabetes tests. They are:
Fasting blood glucose test
Oral glucose tolerance test
Fasting Blood Glucose TestThe variation of blood glucose level is between a very narrow range in normal conditions. These levels are at their peak after having food and at the lowest after an overnight fasting. Fasting blood
glucose test is done after fasting for at least eight hours continuously. This is done in the morning after an overnight fasting of eight hours. Blood sample is taken and sent to the laboratory to test the blood glucose level. A lab result of 100 milligrams of glucose per deciliter of blood is healthy. If the result ranges from 100 mg/dL to 125 mg/dL it assures the presence of
prediabetes and a possibility of diabetes.
Oral Glucose Tolerance Test
Oral glucose tolerance test is second type of
prediabetes test which can also done after a fasting for eight hours, normally overnight. Blood samples are taken when the stomach is empty. Then the person is given eight ounces of sugary liquid to drink. Again after waiting for two hours, the blood samples are taken. The blood sugar level before and after the drink are tested. If the blood sugar result is 140 mg/dL to 199 mg/dL the person is affected by prediabetes.
