Calculates fractional excretion of sodium (FeNa) and urea (FeUrea) to differentiate prerenal from intrinsic renal AKI, with interpretation adjustments for loop diuretics and CKD background.
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.

Each component has a specific meaning:
Note: Interpret the fena feurea aki result against the clinical thresholds and context described above.
Enter the intrinsic renal AKI for the patient or scenario you are assessing. Calculates fractional excretion of sodium (FeNa) and urea (FeUrea) to differentiate prerenal from intrinsic renal AKI, with interpretation adjustments for loop diuretics and CKD background. Use the fena feurea aki result to inform your clinical assessment.
