Urinary creatinine is commonly used as a laboratory standardization when evaluating urinary analytes. Creatinine excretion is influenced by muscle mass and body habitus since creatinine formation occurs in muscle.

Dietary intake of proteins containing arginine and glycine (precursors of creatine) and creatine supplementation can elevate levels.

Hydration status may also play a role in urinary creatinine levels.

As a waste product, creatinine is filtered out of the blood by the kidneys and removed from the body in urine. The amount of creatinine formed daily is based on muscle mass, which varies with age, gender, and ethnicity. It is usually produced at a fairly constant rate in each person. Elevated creatinine can indicate kidney issues and should be evaluated with additional kidney-function testing; however, it is not an early marker for diagnosis of early disease and estimated GFR has become a more useful measurement.

Creatinine values are measured to correct results for urine dilution.

Creatinine is a waste product produced by muscles from the breakdown of a compound called creatine. Creatinine is filtered from the blood by the kidneys and released into the urine.

The amount of creatinine produced in the body is dependent on muscle mass and is relatively constant for an individual. The amount of creatinine removed from the blood depends on both the filtering ability of the kidneys and the rate at which blood is carried to the kidneys.

The urinary creatinine concentration (CC) represents the actual creatinine concentration in the specimen that was submitted.

Under normal conditions, the rate of excretion of creatinine is quite constant and highly correlated with lean body mass (muscle). However, the CC can vary significantly as a function of urine volume.

The evaluation of the creatinine concentration in the urine does only serve as an admeasurement of the individual efficiency of the kidney. High values point to an urine concentration, low values to a strong dilution. Only the consideration of these circumstances allowes to evaluate the requested analyte correctly.

A creatinine test reveals important information about your kidneys.

Creatinine is a chemical waste product of creatine, an amino acid made by the liver and stored in the liver. Creatinine is the result of normal muscle metabolism. The chemical enters your bloodstream after it’s broken down. Your kidneys remove it from your blood. The creatinine then exits the body through urination.
