Creatinine Serum Test
The Creatinine Serum Test measures creatinine levels in a blood sample and helps screen for kidney disease.
What is creatinine?
Creatinine is a byproduct of the metabolization of creatine, a chemical naturally produced in the body that provides muscles with the energy they need. During this process, some creatine breaks down into creatinine. The kidneys then filter the creatinine out of the blood and expel it from the body in urine.
