This test can help detect both pre-diabetes as well as diagnose diabetes. If you are already diabetic, this can help you track your progress in managing your diabetes.
In people with diabetes, insulin is either not produced in a proper quantity or less effective overall which makes it harder to manage the amount of sugar passing through your blood. Look out for signs of high blood sugar levels. They include increased hunger and thirst, frequent urination, blurry vision, fatigue, darkened areas of the folds in the skin, and weight loss.
