Creatinine is the endproduct of creatinine metabolism. Creatinine is present primarily in muscle and the amount of creatinine produced is related to total skeletal muscle mass. Daily creatinine production is fairly constant except when there is a massive injury to muscle. The kidneys excrete creatinine very efficiently and blood levels and daily urinary excretion of creatinine fluctuate very little in healthy normal people. Since blood and daily urine excretion of creatinine show minimal fluctuation.
