Clinical Significance

Creatinine is the end-product of Creatine Metabolism. Creatine 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 massive injury to muscle. The kidneys excrete Creatinine very efficiently and blood levels and daily urinary excretion of Creatinine fluctuates very little in healthy normal people. Since blood and daily urine excretion of Creatinine show minimal fluctuation, Creatinine excretion is useful in determining whether 24-Hour urine specimens for other analytes (e.g., Protein) have been completely and accurately collected. Microalbumin is albumin excreted in the urine and is a sensitive marker of nephropathy. It is used to screen for early renal disease in diabetic patients.
