Fasting Blood Glucose Levels |
The Fasting Blood Sugar test (FBS test) is a basic test to measure the amount of sugar (glucose) in the blood. The normal range for fasting blood glucose in adults is between 70 and 110 mg/dl,
with levels over 140 mg/dl generally indicating a diabetes condition.
Blood samples tested for fasting blood glucose are usually taken in the morning
after an overnight fasting period. Because glucose levels naturally fluctuate in response to meals, medication, stress, and other factors, doctors will often repeat the FBS test to ensure accurate diagnosis based on FBS levels.
Another test is the Oral Glucose Tolerance test (OGTT). Glucose is administered orally and your blood sugar is tested a few hours later. Test results indicating over 200 mg/dl generally indicate a type 2 diabetes condition.
