UACR Kidney Damage Threshold Calculator

Classify albuminuria severity from UACR: A1 (<30 mg/g normal to mildly increased), A2 (30-300 moderately increased), A3 (>300 severely increased).

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 albuminuria severity from UACR: A1 (<30 mg/g normal to mildly increased), A2 (30-300 moderately increased), A3 (>300 severely increased)

Each component has a specific meaning:

  • UACR: A1 (<30 mg/g normal — The uacr: a1 (<30 mg/g normal recorded for the scenario being assessed.

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

How to Use

Enter the UACR: A1 (<30 mg/g normal for the scenario you are assessing. Classify albuminuria severity from UACR: A1 (<30 mg/g normal to mildly increased), A2 (30-300 moderately increased), A3 (>300 severely increased). Use the uacr threshold result to inform your calculation.
