Creatinine Blood Test - More Information
The creatinine test measures the creatinine blood level.
Creatinine is product of normal muscle metabolism in the body. Produced from creatine phosphate, creatinine is a commonly used marker to evaluate the health of the kidneys - its primary source of excretion from the body. Specifically, creatinine levels are correlated with the glomerular filtration rate (GFR) in the kidneys because, after creatinine is filtered by the kidney, very little of it is reabsorbed. Occasionally, urine creatinine levels are used with blood creatinine levels to estimate the GFR.
High creatinine levels are frequently used as a screening marker for worsening GFR and kidney health. Other causes of high creatinine levels include excessive meat consumption, intensive exercise and creatine or protein dietary supplementation.
To get a creatinine test near you, simply order online and get tested at your selected Quest Diagnostics lab. The creatinine test report, similar to the sample report link above, will report your creatinine level as a number which can be compared against the reference range in mg/dL.
