However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.

At what age does kidney function start to decline?

The general “Rule of Thumb” is that kidney function begins to decline at age 40 and declines at a rate of about 1% per year beyond age forty. Rates may differ in different individuals.

How does creatinine change with age?

Findings: Serum creatinine concentration increased steadily with age; in females from the age of 40 years and 60 years for males. Reference intervals for males and females aged from 20 to 94 years were established. Advancing age affects serum creatinine levels, especially in the “vascular” age group of 60 to 80 years.
