Blood glucose screening tests for diabetes, insulin resistance, hypoglycemia and acromegaly, or disorders of carbohydrate metabolism. The most commonly performed version of the test is an oral glucose tolerance test (OGTT), a standard dose of glucose is ingested by mouth and blood levels are checked two hours later.
A single blood glucose test result only gives information about an individual's blood glucose level at one particular point in time. A series of self-monitored blood glucose measurements over a period of time can give valuable information about an individual's diabetes health. Blood glucose records should be assessed by a health care professional with expertise in diabetes.
