Experts do not recommend routine testing for type 1 diabetes. Experts differ on when is the best time to start testing for type 2 diabetes. Talk with your doctor about what is putting you at risk for diabetes and whether you should be tested.
The Canadian Task Force on Preventive Health Care (CTFPHC) recommends using a risk calculator such as the Canadian Diabetes Risk Questionnaire (CANRISK) to determine your level of risk. Go to www.healthycanadians.gc.ca/en/canrisk to use the CANRISK tool. The CTFPHC recommends:footnote 1
Not testing if you have low to moderate risk.
Testing every 3 to 5 years with an A1c test if you are at high risk.
Yearly testing with an A1c test if you are at very high risk.
Diabetes Canada recommends testing every 3 years if you are age 40 or older. If you are at very high risk, the Diabetes Canada recommends that you get tested more often and/or begin testing at a younger age. You are at risk for diabetes if:footnote 2
You have a parent, brother, or sister who has type 2 diabetes.
You are of Indigenous, African, Hispanic, Asian, or South Asian descent.
You have prediabetes. This means your blood sugar is above normal but is not high enough to be diabetes.
