Spot urine creatinine

Important: Inputs must be complete to perform calculation.


Urine protein-to-creatinine ratio		mg/mg

Decimal precision

Notes

Upper limit of normal for the spot urine protein-to-creatinine ratio varies by age as follows:
- Age 6 to 24 months (infants and toddlers) <0.5 mg protein/mg creatinine.
- Age 24 months to 18 years (children and young adults) <0.2 mg protein/mg creatinine.
The spot urine protein-to-creatinine ratio that is indicative of nephrotic range proteinuria is >3 mg protein/mg creatinine.

Equations used

Urine protein-to-creatinine ratio = Spot urine protein / Spot urine creatinine
