If you are concerned about the possibility of yourself or someone that you care about being diagnosed as pre-diabetic, then it is time to start taking action now. One of the things that you can do immediately is purchase a blood glucose level home checker to see if those sugar levels fall into the pre-diabetes condition territory. Or, you can go to your doctor and ask to have those blood glucose levels tested.
There are two different blood sugar level tests that your family doctor can run.
The fasting blood sugar test requires that a blood sample be taken after you fast for at least eight hours or overnight. With this test, a blood sugar level lower than 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is normal. A blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. This is sometimes referred to as impaired fasting glucose (IFG). A blood sugar level of 126 mg/dL (7.0 mmol/L) or higher may indicate diabetes mellitus.
With the oral glucose tolerance test, a blood sample will be taken after you fast for at least eight hours or overnight. Then you’ll drink a sugary solution, and your blood sugar level will be measured again after two hours. A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A blood sugar level from 140 to 199 mg/dL (7.8 to 11.0 mmol/L) is considered prediabetes. This is sometimes referred to as impaired glucose tolerance (IGT). A blood sugar level of 200 mg/dL (11.1 mmol/L) or higher may indicate diabetes mellitus.
