India-specific
Indian Diabetes Risk Score (MDRF-IDRS)
The MDRF Indian Diabetes Risk Score identifies people who should be screened for undiagnosed type 2 diabetes, using four questions and no blood test. It was developed and validated in an Indian population, which is why it is used here in preference to imported risk scores.

The formula
- Age: under 35 → 0 · 35–49 → 20 · 50 and over → 30
- Waist: below the Asian-Indian cut-off → 0 · borderline → 10 · above → 20
- Physical activity: vigorous → 0 · moderate → 20 · mild or none → 30
- Family history: neither parent → 0 · one parent → 10 · both parents → 20
- Total range 0 to 100; 60 or more is high risk
Worked example
A 52-year-old with a 95 cm waist (man), a sedentary job and one diabetic parent → 30 + 10 + 30 + 10 = 80, high risk
When to use it
- Community screening for undiagnosed type 2 diabetes in India
- Deciding who needs a fasting glucose or HbA1c
And when not to
- It identifies who to test. It does not diagnose diabetes, which needs a blood test.
- It was validated in an Indian population and should not be assumed to transfer elsewhere.
- Waist cut-offs here are the Asian-Indian ones, which are lower than the international thresholds.

These calculators are free and always will be. We also build Nirogix, a hospital management system for Indian clinics and hospitals. The same calculations are planned inside the consultation record, pre-filled from the chart.
