clinical definition of 24-hour urinary protein

Proteins are the "building blocks" of the body. When the kidneys are healthy, no proteins pass into the urine. However, if the kidneys become diseased or damaged, the proteins may appear in the urine.

Hence the urine protein test may be used to screen for kidney disease, to monitor kidney function in those already diagnosed with a kidney disease or those who are taking medications that can affect the kidneys.

why get tested?

A 24-hour urine protein measures the total amount of protein excreted in urine collected over a 24-hour period. Sometimes, in order to avoid the inconvenience and possible inaccuracy of a 24-hour urine collection, the protein-to-creatinine ratio may be done instead.

Protein-Creatinine Ratio (PCR) - The concentration of protein in the urine is compared to the creatinine level in a spot urine sample. It may be used to monitor persistent proteinuria i.e. presence of an excess of serum proteins in the urine. The protein in the urine often causes the urine to become foamy.
