Creatinine (/kriËÃ¦táµ»náµ»n/ or /kriËÃ¦táµ»niËn/; from Greek: ÎºÏÎ­Î±Ï, translit. kreas, lit. 'flesh') is a breakdown product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass).
Creatinine is a waste product that is produced continuously during normal muscle breakdown. The kidneys filter creatinine from the blood into the urine, and reabsorb almost none of it. The amount of blood the kidneys can make creatinine-free each minute is called the creatinine clearance.reatinine is a waste product that is produced continuously during normal muscle breakdown.
