World Diabetes Day: How to Read Your Blood Sugar Result

A fasting result of 7.0 mmol/L or more, a random result of 11.1 or more, or an HbA1c of 6.5% or more points to diabetes. Here is what your number means.

What your blood sugar number actually means

You did a sugar test at a pharmacy and walked out with a number on a slip of paper. What does it actually mean?

Fasting test (no food for at least 8 hours): below 6.1 mmol/L (110 mg/dL) is normal. 7.0 mmol/L (126 mg/dL) or higher suggests diabetes.

Random test (any time of day): 11.1 mmol/L (200 mg/dL) or higher suggests diabetes, especially with thirst, frequent urination or weight loss.

HbA1c (your average sugar over about three months): 6.5% or higher suggests diabetes.

One high reading is a signal, not a final verdict, and a doctor will usually repeat the test. If your number is borderline or high, see a doctor this month, not next year.
