Creatinine quantification is an important basis for doctors to accurately assess the patient's kidney function. Creatinine will be assessed through blood or urine tests.

The creatinine clearance test is performed to clinically evaluate kidney function. From there, this test helps doctors detect early stage kidney failure and other diseases to provide the most appropriate treatment regimen.

Blood creatinine is a catabolic product of creatine phosphate. Creatinine has exogenous sources from food and endogenous sources from the liver, kidney, and pancreas. Testing the quantity of creatinine in the blood will help us know many health problems, including impaired kidney function.
