What is the typical daily excretion range of creatinine for adults?

The typical daily excretion range of creatinine for adults is generally around 1.2 to 1.5 grams per day. This range reflects the production of creatinine, which is a breakdown product of creatine phosphate from muscle metabolism. The actual amount of creatinine excreted can vary based on several factors, including an individual's muscle mass, diet, and level of physical activity.

Creatinine is usually produced at a relatively constant rate, making it a useful marker for assessing kidney function. Deviations from the typical range can indicate issues related to kidney function, muscle mass changes, or variations in dietary protein intake. Understanding the normal range is crucial for interpreting laboratory results in clinical practice effectively.
