BLOOD GLUCOSE TEST

Blood Glucose Test

Blood glucose test is used to screen the sugar level in your body.  Normal blood glucose level (while fasting) range within 70 to 99 mg/dL (3.9 to 5.5 mmol/L). Higher ranges could indicate pre-diabetes or diabetes.

How should you prepare?

If you are asked to fast, you can’t eat anything for 8 to 10 hours before the test. You should drink only water. Fasting tests are more common because they provide more accurate results and are easier to interpret.

If you are not asked to fast, you can take any time. This type of test is called as random blood glucose test.

How to interpret the results?

Fasting blood glucose level

•  If your blood glucose level is 70 to 99 mg/dL (3.9 to 5.5 mmol/L).

          Your glucose level is within the normal range

• If your blood glucose level is 100 to 125 mg/dL (5.6 to 6.9 mmol/L).

         You have an impaired fasting glucose level (pre-diabetes).

• If your blood glucose level is 126 mg/dl (7.0 mmol/L) or higher on more than one testing occasion

         You have diabetes

Random blood glucose level

• If your blood glucose level is under 125 mg/dL (6.7 mmol/L).

         Your glucose level is within the normal range

• If your blood glucose level is 140–199 mg/dL (7.8 to 11.1 mmol/L).

         You may have prediabetes.

• If your blood glucose level is 200 mg/dL (11.1 mmol/L).

         You have diabetes
