creatinine Formed non‐enzymically from creatine (chemically the anhydride of creatine). Urinary excretion of creatinine is relatively constant from day to day, and reflects mainly the amount of muscle tissue in the body. Therefore the amounts of various components of urine are often expressed relative to creatinine.
