Urine Protein to Creatinine Ratio - Normal Value

The protein-creatinine ratio (UP:UC) is used to provide an estimate of the amount of protein lost in the urine. It’s used to help evaluate kidney function.

The urine sample can be either of the three types:

  • a single sample at any time
  • a 24-hour urine sample
  • a split 24-hour sample, with the night (11pm-7am) collection separated from the day collection (7am-11pm)

When doctors order urine test they often order blood test as well.

The normal protein to creatinine ratio for males 18-83 years is <0.11 mg/mg creatinine. For females 18-83 years it’s <0.16 mg/mg. 

The protein to creatinine ratio is used to roughly approximate the 24-hour excretion rates.
