Urine Albumin-Creatinine Ratio (UACR) Calculator

7 comments

This calculator helps assess kidney function by calculating the urine albumin-to-creatinine ratio (UACR). It’s a standard test for detecting early kidney damage, especially in individuals with diabetes or hypertension.

Input Fields
ua
mg/dL
Urinary albumin concentration
uc
g/dL
Urinary creatinine concentration
If enabled, the result will update automatically when you change any value.

UACR Calculation Formula

Formula
$$UACR = \frac{UA}{UC}$$

Where:

  • $$UA$$ = Urine Albumin concentration (mg/dL)
  • $$UC$$ = Urine Creatinine concentration (g/dL or mg/dL depending on unit matching)
  • $$UACR$$ is usually expressed in mg/g or mg/mmol


The Urine Albumin to Creatinine Ratio (UACR) is a vital indicator of kidney health. It allows clinicians to estimate how much albumin is being lost in the urine relative to creatinine concentration, helping to detect microalbuminuria or more severe proteinuria. Early detection is especially important for patients with diabetes, hypertension, or chronic kidney disease. A UACR value above 30 mg/g typically indicates abnormal protein excretion.
