Who Should be Screened? Using The Canadian Diabetes Risk Questionnaire (CANRISK)
Case Study
Mr. AW, 42-years old, presents today in your office. He was at his local pharmacy where he had completed the Canadian Diabetes Risk Questionnaire (CANRISK). Having received a score of 33 (high risk), it was recommended that he make an appointment to see his physician for further diabetes workup.
Mr. AW qualifies for screening on a variety of levels:
High risk based on risk calculator
Individuals ≥ 40 should be screened every three years
In addition, Mr. AW has the following risk factors:
Age ≥ 40
First-degree relative with type 2 diabetes
Member od high-risk population: Asian
Overweight
Abdominal obesity
These factors are used to calculate his CANRISK score. Further investigation would probably reveal additional risk factors.
What tests should be ordered to screen for diabetes?
FPG A1C FPG and A1C

You are correct!
You are correct!
Diabetes Canada’s Guidelines suggest screening with a FPG and/or A1C. In this case, a FPG and A1C is ordered.
Screening tests for type 2 diabetes reveal the following results:
FPG: 5.8 mmol/L
A1C: 6.3%
What would be the next steps?
Repeat both tests (FPG and the A1C)
Repeat the “higher” test
Initiate healthy behaviour interventions
Reveal Answer
You are correct!
That answer is incorrect.
Initiate healthy behaviour interventions.
Mr AW has prediabetes and repeat testing is not required. An OGTT can be considered, but is not mandatory. Healthy behaviour interventions and or dietary patterns shown to reduce the risk of type 2 diabetes should be instituted (see chapter "Reducing the risk of developing diabetes") and FPG and/or A1C should be repeated in 3-6 months.
