Creatinine is a breakdown product in muscle. It’s removed from the blood chiefly by the kidneys. When the blood is filtered in the kidney, the creatinine is transferred to the urine and leaves the body. If the filtration in the kidney is deficient, creatinine blood levels rise. Measuring serum creatinine is a simple test, and it is the most commonly used indicator of the kidney’s condition.
