From the body it is excreted by the kidneys along with urine, thus violating the indicators creatinine speaks primarily about the presence of diseases of the urinary or muscular systems.
Normal levels of creatinine in the blood vary in the range 53-98 mmol/l for women and 55-116 µmol/l in men. During normal operation, the kidney per day in men should stand out from the urine about 8.8 and 17.6 mmol (1.0-2.0 g) of creatinine, and for women and 7.2-15.8 mmol (0.8 to 1.8 g).
