Is fasting blood sugar 7.1 diabetes?

Fasting blood glucose test value of 7.1 may be caused by diabetes, but it cannot be diagnosed. Oral glucose tolerance test is also needed to confirm whether diabetes is present. If it has been diagnosed, oral hypoglycemic drugs should be prescribed to control blood sugar. For those who fail to respond to hypoglycemic drugs, subcutaneous insulin can also be used to control blood sugar.
