Risk Assessment Test


Risk profile

The following is a list of risk factors associated with diabetes development.

Age itself is a risk factor; therefore, anyone older than 45 years of age should have a diabetes screening test even in the absence of other risk factors.

For those younger than 45 years of age, with no symptoms, but having two or more risk factors, a screening test is appropriate.

If tested negative, the screening test should be repeated every 3 years.

  • Age 45 years or older
  • Obesity, BMI greater than 25 kg/m² with one or more of the factors below:
    • First degree related family member such as a parent or brother, sister with diabetes mellitus
    • History of gestational diabetes or delivering a baby weighing more than 4 kg
    • Polycystic ovary syndrome
    • Physical inactivity: not taking part in any formal regular exercise
    • Blood pressure greater than or equal to 140/90 mmHg, or on treatment for high blood pressure
    • Raised cholesterol on dietary control or using medication
    • Cardiovascular disease including heart attack, angina, previous bypass or stenting
    • Previous detected IGT (impaired glucose tolerance) or IFG (impaired fasting glucose)
    • Prolong use of certain medications including thiazide diuretics, beta-blockers, glucocorticoids, phenytoin, interferon


Screening tests and diagnostic tests

Screening test is an investigation performed in an individual with no symptoms of diabetes to evaluate the risk of having diabetes.

Diagnostic test is an investigation performed in an individual who is suspected to have diabetes based on symptoms or history.

For diabetes, identical laboratory tests are performed for both screening and diagnosis.  Some of these tests can also pick up if you have any of the pre-diabetes conditions called Impaired Glucose tolerance or Impaired Fasting Glucose. This is the best time to take action and prevent full diabetes from developing. Speak to us.


Tests available


Fasting plasma glucose

This is a blood test taken at the laboratory after fasting for 8 hours or longer which test for the blood glucose level.

Oral glucose tolerance test

This is a test involving taking a series of blood samples which evaluates blood glucose levels before and after stimulation by ingestion of a sugar load. This takes about 2 hours; it is the most comprehensive evaluation.


This is one single blood sample tested at an accredited laboratory requiring no fasting.
