WebJul 2, 2024 · Creatinine tests are used to screen, diagnose, and monitor kidney (renal) disorders, including chronic kidney disease and acute renal failure. They can also be used … Serum creatinine (a blood measurement) is an important indicator of kidney health, because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced via a biological system involving creatine, phosphocreatine (also known as creatine phosphate), and adenosine triphosphate (ATP, the body's immediate energy supply). kiss jingle ball ticket prices
