Frequently Asked Questions

A blood sugar test is used to diagnose diabetes. Usually, your doctor will recommend it when they suspect an increase or decrease in the level of sugar in your blood. It is also routinely used for diabetics to monitor their blood sugar levels.

The normal blood sugar level is less than 140 mg/dL. A blood sugar level between 140 mg/dL and 200 mg/dL indicates prediabetes. You may have diabetes if your blood sugar level is greater than or equal to 200 mg/dL.

Fluctuation in blood sugar levels may cause hypoglycemia or hyperglycemia. It may also indicate diabetes. Once your doctor identifies the symptoms, they might advise you to undergo this test to identify the exact condition. This also helps the doctor to prepare a treatment plan for you.

A simple blood sugar test can be done at home or in a clinic by your doctor. It involves the use of a glucose meter. The meter displays the quantity of sugar in a small sample of blood that you place on a disposable test strip, generally from your fingertip. You may receive findings in less than 15 seconds and save the data for further use.

A blood sugar level lower than 140 mg/dl (7.8 mmol/L) is considered normal.
