Research Notes on Creatinine
Creatinine is a break-down product of creatine phosphate in muscle and is usually produced at a fairly constant rate by the body. Creatinine is mainly filtered by the kidney, though a small amount is actively secreted. There is little to no tubular reabsorption of creatinine. If filtering of the kidney is deficient, the blood levels rise. Measuring serum creatinine is a simple test and it is the most commonly used indicator of renal function.1
