What does elevated creatinine levels usually indicate?

Elevated creatinine levels are typically a strong indicator of renal failure. Creatinine is a waste product formed from muscle metabolism and is normally excreted by the kidneys. When the kidneys are not functioning properly, they are unable to efficiently filter out creatinine from the blood, leading to increased serum creatinine levels.

This relationship is crucial in diagnosing and managing kidney health. While other conditions, such as dehydration or muscle mass changes, can also affect creatinine levels, a significant elevation is most frequently associated with impaired kidney function. Understanding this correlation is essential for assessing and addressing renal issues in patients.
