Albumin-Creatinine Ratio Calculator
Calculate the urine Albumin-to-Creatinine Ratio (ACR) to screen for microalbuminuria and kidney disease.
Input Parameters
Enter details for calculation.
Urine ACR
Expert Tip
Normal ACR is < 30 mg/g. Microalbuminuria is 30-300 mg/g; macroalbuminuria is > 300 mg/g, indicating diabetic nephropathy.
Calculation Methodology & Details
Formula
Normalizes albumin concentration to creatinine excretion to account for urine concentration.
