اندازه گیری کراتینین(Creatinine) And phosphocreatine Creatine Cteatine is formed from amino acids and plays a role in converting food into energy. We get some creatine from our diets, mostly from meat and fish, and our bodies make the rest naturally. Creatine is  naturally produced in the human body from the amino acide glysine and arginine. Creatine, which is synthesized in the liver and kidneys, is transported through the blood and taken up by tissues with high energy demands, such as the brain and skeletal muscle, through an active transport system. phosphagen (or ATP/PCr) system rapidly resynthesizes ATP from ADP with the use of phosphocreatine (PCr) through a reversible reaction with the enzyme creatine kinase (CK). The increased creatine in the muscle may allow larger stores of phosphocreatine to build, and provide extra energy in the form of adenosine triphosphate. Creatinine Creatinine is synthesized in the body at a fairly constant rate from creatine, which is produced during muscle contractions from creatine phosphate. In the blood, creatinine is removed by filtration through the glomeruli of the kidney and is secreted into urine.  Little or no tubular reabsorbtion of creatinine occurs creatinine secretion is independent of diet and is fairly constant. The creatinine clearance test has become one of the most sensitive tests for measuring glomerular filtration rate. Creatinine test is most widely used to assess kidney function. The best indicator of kidney function is considered to be the rate that blood is filtered at the glomerulus, or glomerular filtration rate (GFR).
