Diabetes, Type 2—Clinician FINDRISC

PDF Version


Using the Risk Calculator, determine your patient’s risk score, then use the results table to calculate your patient’s diabetes risk. Please note that there is a corresponding Type 2 Diabetes Risk Calculator for Patients.

Please note: Recommendations are presented for screening asymptomatic adults for type 2 diabetes using blood tests. These recommendations do not apply to adults already diagnosed with type 2 diabetes, those at risk for type 1 diabetes, or those with symptoms of diabetes. Symptoms of diabetes include: unusual thirst, frequent urination, weight change (gain or loss), extreme fatigue or lack of energy, blurred vision, frequent and recurring infections, cuts and bruises that are slow to heal, and/or tingling or numbness in the hands or feet.


Add up points to determine your patient’s total risk score.

Use your patient’s results from the risk calculator in the results table to determine the Canadian Task Force on Preventive Health Care (CTFPHC)’s screening recommendations.

Risk calculator

  1. How old is your patient?

a. 18–44 years (0 points)

b. 45–54 years (2 points)

c. 55–64 years (3 points)

d. 65 years or older (4 points)

2. What is your patient’s body-mass index (BMI) category?

Visit bmi-calculator.net for a BMI calculator

a. Normal (Lower than 25.0 kg/m²) (0 points)

b. Overweight (25.0–29.9 kg/m²) (1 points)

c. Obese (30.0 kg/m² or higher) (3 points)

3. What is your patient’s waist circumference?

Waist circumference is measured below the ribs (usually at the level of the navel).

a. Less than 94 cm (less than ~ 37 inches) for men; or Less than 80 cm (less than ~ 31 inches) for women (0 points)

b. 94–102 cm (~ 37–40 inches) for men; or 80–88 cm (~ 31–35 inches) for women (3 points)

c. More than 102 cm (more than ~ 40 inches) for men; or More than 88 cm (more than ~ 35 inches) for women (4 points)

4. Is your patient physically active for more than 30 minutes every day?

This includes physical activity during work, leisure, or regular daily routine.

a. Yes (0 points)

b. No (2 points)

5. How often does your patient eat vegetables and fruits?

a. Every day (0 points)

b. Not every day (2 points)

6. Has your patient ever taken medications for high blood pressure on a regular basis?

a. No (0 points)

b. Yes (2 points)

7. Has your patient ever been found to have high blood glucose (e.g. in a health examination, during an illness, during pregnancy)?

a. No (0 points)

b. Yes (5 points)

8. Have any members of your patient’s immediate family or other relatives been diagnosed with diabetes (type 1 or type 2)?

This question applies to blood relatives only.

a. No (0 points)

b. Yes: grandparent, aunt, uncle, or first cousin (but not own parent, brother, sister, or child) (3 points)

c. Yes: parent, brother, sister, or own child (5 points)


Score Risk  Recommendation
0–14 points Low to moderate risk

1-17% chance of developing diabetes within 10 years.

We recommend not screening for type 2 diabetes.
15–20 points High Risk

33% chance of developing diabetes within 10 years.

We recommend screening every 3–5 years with A1c.
21–30 points Very High Risk

50% chance of developing diabetes within 10 years.

We recommend annual screening with A1c.


Risk calculator choice

The CTFPHC selected FINDRISC as the preferred risk questionnaire because it has been validated and has similar test accuracy to the Canadian Diabetes Risk Questionnaire: CANRISK. Its use has led to improved patient important outcomes (e.g. reduced incidence of diabetes when combined with an educational intervention).

Patient important outcomes are outcomes that are of particular relevance to and valued by patients, including things like quality of life, pain control or other symptom relief, etc. The literature review did not identify any studies reporting on the impact of CANRISK on patient important outcomes. CANRISK has only been validated in a cross sectional convenience sample of patients and is longer than FINDRISC.

There is no evidence to guide the optimal frequency of risk calculation. Based on evidence for screening interval, the CTFPHC suggests risk calculation at least every 3–5 years for adults 18+ years of age.

Screening test choice

The CTFPHC selected A1c as the preferred screening test, but noted that the fasting glucose measurement and the glucose tolerance test are acceptable alternatives. A1c is commonly referred to as glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1c, HbA1c, Hb1c, or HbA1c. A1c of 6.5% is recommended as the cut point for diagnosing diabetes but a value less than 6.5% does not exclude diabetes diagnosed using glucose tests. A1c should be measured using a standardized, validated assay.
