About Diabetes Testing

Diabetes affects how your body processes glucose. Left untreated, it can cause serious complications. Early detection through testing helps manage or even reverse prediabetes.

Test Options

  • HbA1c Test: Measures average blood sugar over 3 months (no fasting needed).
  • Finger-Prick Test: Instant glucose level reading (fasting required).
  • Oral Glucose Tolerance Test (by referral): For gestational diabetes.

Interpreting Results

HbA1c results:

  • Normal: Below 42 mmol/mol.
  • Prediabetes: 42–47 mmol/mol.
  • Diabetes: 48 mmol/mol or higher.

Who Should Get Tested?

Adults over 45, or those with:

  • Symptoms like thirst, frequent urination, or fatigue.
  • BMI over 25 or family history of diabetes.
  • High blood pressure or gestational diabetes history.
