Urine creatinine test
Quick answer: A urine creatinine test measures creatinine, a muscle waste product, in a 24-hour collection or a single urine sample. It is used with blood creatinine to measure kidney function, or to check how concentrated urine is when other urine tests are done.

A high level can be seen with high muscle mass, a high-meat diet or very concentrated urine. A low level can be seen with reduced kidney function, low muscle mass or very dilute urine.
Who usually has this test
People having kidney function checks, and people having other urine tests where creatinine is used to allow for urine concentration.
Risks and aftercare
There is no physical risk, but missing a sample during a 24-hour test can affect the result.

Questions about this test
What is creatinine clearance?
It compares creatinine in 24-hour urine with blood creatinine to estimate how well the kidneys filter. It needs both a urine and a blood sample.
Why is urine creatinine measured with other urine tests?
It helps correct for how dilute or concentrated your urine is. Results are often given as a ratio, such as protein-to-creatinine.
Does meat affect urine creatinine?
Yes. Eating a lot of cooked meat can raise creatinine. Your doctor may ask you to avoid large meat meals before the test.
