Creatinine, a type of molecular waste found in the blood, is created by muscle metabolism. It comes from the molecule creatine, which helps build muscle mass. Creatinine is filtered from the blood by the kidneys and expelled from the body in urine. However, people with kidney impairment sometimes cannot properly filter out creatinine. A high blood creatinine level is an indicator that a person may have a kidney problem. http://www.emasherbs.com/

Creatinine Serum creatinine levels provide a more sensitive measure of renal damage than do blood urea nitrogen levels. Creatinine is a nonprotein end product of creatinine metabolism that appears in serum and amounts proportional to the body’s muscle mass.
