Three basic Methods of examining for Diabetes

Diabetes increasingly become a major public health problem in recent years. Over 120 million people in the United States. Diabetes, most of them with type 2 diabetes. How to start the federal government and insurance companies for increasing healthcare costs of diabetes and its accompanying problems, this is a great incentive to begin to determine the risk of developing diabetes before they actually chronic diseases.

One way to solve this problem with various types of preliminary tests of diabetes. Diabetes is a metabolic disorder in which a person is more sugar in the blood. You can try, but simply drawing blood and measuring blood glucose. This is because a significant proportion of the population have normal levels of blood glucose during the day, but also increased levels of blood sugar after eating all day. Any valid test for diabetes should be considered.


1) random or casual plasma glucose test - the patient can check in any time of day. According to the American Diabetes Association, the review of casual glucose concentration in plasma of 200 milligrams per deciliter (mg / dl), says it has reached the criteria for the diagnosis of diabetes.

2) fasting plasma glucose (FPG) test - often called the measurement of fasting blood glucose, due to the fact that the patient must be fast before the test. In this context, means a fast that the patient not to eat or drink except water for at least 8 hours before testing. This test is probably the most convenient for the patient, the first thing in the morning after sleeping at night. Measures to control blood sugar levels in the blood. The fasting blood glucose is normal after about 100 mg / dl. When the concentration of glucose is 126 mg / dl or more, a diagnosis of diabetes can be done. Tracking measurements of blood glucose continues throughout the day. This test is very popular with insurance companies and health care providers because it is relatively inexpensive.
This is also true for the test model pre-diabetes.

3) the oral evidence of oral glucose tolerance test (OGTT) - This is the most comprehensive testing as the best by many. Is more sensitive than the test of fasting plasma glucose, and can be used to test for glucose intolerance, the other two did not. However, it is also more expensive, making it the least popular among insurance companies and healthcare providers. The test is performed two hours after oral administration of 75 g glucose. If the blood sugar of 200 mg / dL or more are diagnosed with diabetes can do.

It is possible that the test can be used for different reasons to give false positive results and show that a person, diabetes, although it is not, in fact. Therefore, whenever a positive result should be repeated to confirm results.
