Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate IgA nephropathy clinical risk score using proteinuria, blood pressure, eGFR, and histology to predict 5-year ESRD/50% eGFR loss risk

Each component has a specific meaning:

  • Proteinuria — The proteinuria recorded for the scenario being assessed.
  • Blood pressure — The blood pressure recorded for the scenario being assessed.
  • EGFR — The egfr recorded for the scenario being assessed.
  • Histology — The histology recorded for the scenario being assessed.

Note: Interpret the igan progression risk result against the thresholds and context described above.

How to Use

Enter the proteinuria, blood pressure, eGFR, histology for the scenario you are assessing. Calculate IgA nephropathy clinical risk score using proteinuria, blood pressure, eGFR, and histology to predict 5-year ESRD/50% eGFR loss risk. Use the igan progression risk result to inform your calculation.
