Urine albumin to creatinine ratio   mg/g
 
Decimal precision  

 
 

 
Notes
  • The normal urine albumin to creatinine ratio is less than 30 mg/g.
  • Ratios between 30 and 299 mg/g are called "moderately increased albuminuria," which was formerly called "microalbuminuria."
  • Ratios of 300 mg/g or higher are called "severely increased albuminuria," which was formerly called "macroalbuminuria."
  • Please refer to UpToDate topics on urinary protein excretion and staging of chronic kidney disease for more information on the clinical use of the spot urine albumin-to-creatinine ratio.

 
Equations used
 
Urine_albumin_to_creatinine_ratio = 1000 * Spot_urine_albumin / Spot_urine_creatinine
