Creatinine is a break-down product of creatine phosphate in muscle tissue. It is usually produced at a fairly constant rate. Creatinine is cleared by the kidneys with minimal tubular reabsorption. Creatinine accumulates in the blood when GFR decreases in the setting of renal dysfunction. As a result, serum creatinine levels are commonly used as a surrogate for GFR and renal function.
