Diabetes Test

Diabetes TestA person that has started to show the signs of diabetes will need to take a diabetes test to determine whether the symptoms are indeed caused by the disease. Although there are trials that can be administered at home, most experts recommend that a local physician is visited to make the test for diabetes. There are three main forms of evaluation that may be used by the doctor to find out if the patient has the condition.

The first way to evaluate the disease is to use a fasting plasma glucose test, also known as an FPG. With this examination, the person does not ingest any food for a period of eight hours and then has their level of blood sugar examined. The results of this experiment will show whether enough insulin is being produced to break down the sugars in the blood. The FPG is scored with a numerical rank. Below 100 points indicates a person who is normal, between 100 and 125 indicated a pre-diabetes condition, and over 125 is a person that has diabetes.

Another way to experiment with this problem is to use an OGTT examination. Short for oral glucose tolerance test, this method of testing the body's insulin response also uses a fasting period of eight hours before a patient is tested. After the fast, the person is given a beverage that is high in glucose. After waiting two hours, a blood sugar reading is taken to see the insulin response. The benefit of the OGTT examination is that it has more sensitivity to the condition than the FPG test. In a similar manner, the OGTT is scored with a numerical system. For children and pregnant women, there are other specific forms of the diabetes test that can be used to determine the existence of the condition.
