Calculate ACR for kidney function assessment
Note: The Albumin Creatinine Ratio (ACR) is used to assess kidney function and detect proteinuria.
Clinical judgment should always be used in conjunction with other laboratory values and patient assessment.

ACR Reference Ranges
Normal: < 30 mg/g
Microalbuminuria: 30-300 mg/g
Macroalbuminuria: > 300 mg/g
Formula: ACR = (Albumin mg/L) / (Creatinine mg/L) × 1000
Microalbuminuria: 30-300 mg/g
Macroalbuminuria: > 300 mg/g
Formula: ACR = (Albumin mg/L) / (Creatinine mg/L) × 1000
