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

Stage acute kidney injury using the KDIGO 2012 criteria based on serum creatinine rise (absolute and relative) and urine output to guide management and nephrology involvement

Each component has a specific meaning:

  • KDIGO 2012 criteria based on serum creatinine rise (absolute — The kdigo 2012 criteria based on serum creatinine rise (absolute recorded for the scenario being assessed.
  • Relative) — The relative) recorded for the scenario being assessed.
  • Urine output — The urine output recorded for the scenario being assessed.

Note: Interpret the kdigo aki result against the thresholds and context described above.

How to Use
