Fasting Blood Glucose Test

Fasting Blood Glucose Test

When we talk about Fasting Blood Glucose Test we are actually talking about a glucose test.  Simple!!

Amounts of glucose in your blood fluctuates, but within a very narrow range.  Blood glucose levels are typically at their highest after a meal and at their lowest after an overnight fast.  The best way to test your blood glucose is after you have fasted overnight or for at least 8 hours.  This is called a Fasting Blood Glucose Test.

Blood will be drawn from a vein and sent out to a laboratory for evaluation.  A fasting blood glucose level under 100 milligrams of glucose per deciliter of blood (mg/dL) is considered normal.  If the glucose level measures 100 to 125 mg/dL, then you have what is considered impaired fasting glucose, which is often referred to as prediabetes.  Prediabetes shouldn’t be taken lightly.  It’s a sign that you might be at risk of developing diabetes.  You should get in and see your doctor on a regular basis and take steps to control your glucose.

After 2 tests, your glucose results are 126 mg/dL or higher after at least 8 hours of fasting, you have diabetes.  If your blood glucose is above 200 mg/dL , with symptoms of diabetes, a second test may not be necessary to reach the diagnosis.

Always consult with your doctor when you are about to take a Fasting Blood Glucose Test.
