UACR — Urine Albumin-to-Creatinine Ratio Risk Staging

Classify CKD risk using the Urine Albumin-to-Creatinine Ratio (UACR) into KDIGO albuminuria categories: A1 (<30), A2 (30–300), A3 (>300 mg/g) combined with GFR for comprehensive kidney disease risk staging.

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

Classify CKD risk using the Urine Albumin-to-Creatinine Ratio (UACR) into KDIGO albuminuria categories: A1 (<30), A2 (30–300), A3 (>300 mg/g) combined with GFR for comprehensive kidney disease risk staging

Each component has a specific meaning:

  • Urine Albumin-to-Creatinine Ratio into KDIGO albuminuria categories: A1 — The urine albumin-to-creatinine ratio into kdigo albuminuria categories: a1 recorded for the scenario being assessed.
  • A2 — The a2 recorded for the scenario being assessed.
  • A3 combined — The a3 combined recorded for the scenario being assessed.

Note: Interpret the uacr risk stage result against the thresholds and context described above.

How to Use

Enter the Urine Albumin-to-Creatinine Ratio into KDIGO albuminuria categories: A1, A2, A3 combined for the scenario you are assessing. Classify CKD risk using the Urine Albumin-to-Creatinine Ratio (UACR) into KDIGO albuminuria categories: A1 (<30), A2 (30–300), A3 (>300 mg/g) combined with GFR for comprehensive kidney disease risk staging. Use the uacr risk stage result to inform your calculation.
