  • Protein and Creatinine
  • Item Catalog Number: LC003129

Your kidneys filter waste products from your blood while retaining components your body needs — including proteins. Low levels of protein in urine are normal. Temporarily high levels of protein in urine aren't unusual either, especially after exercise or during an illness.  However, some diseases and conditions can allow proteins to pass through the filters of your kidneys, causing protein in urine. 

A protein to creatinine ratio may used if a person occasionally has some degree of protein in their urine without apparent kidney dysfunction. The test may also be used to monitor people with chronic kidney disease.

Fasting is not required. Take all medications as prescribed.
