BACKROUND

Creatinine is a metabolite of phosphocreatine (p-creatine), a molecule used as a store for highenergyphosphate that can be utilized by tissues for the production of ATP. Creatine either comes from the diet or issynthesized from the amino acids arginine, glycine, and methionine. This occurs in the kidneys and liver,although other organ systems may be involved and species-specific differences may exist. Creatine and pcreatine are converted non-enzymatically to the metabolite creatinine, which diffuses into the blood and isexcreted by the kidneys. In vivo, this conversion appears to be irreversible and in vitro it is favored by highertemperatures and lower pH. Creatinine forms spontaneously from pcreatine, and under normal conditions,its formation occurs at a relatively constant rate. Intra-individual variation of creatinine levels is <15% fromday to day, making it a useful marker for normalizing levels of other molecules found in urine. Alteredcreatinine levels may be associated with conditions that result in decreased renal blood flow, such asdiabetes and cardiovascular disease
