What Is the Normal GFR Range by Age? Understanding Kidney Function Levels
Learn the normal GFR values for different ages and how kidney function changes over time. Know when to monitor your Glomerular Filtration Rate.
0 views
Normal Glomerular Filtration Rate (GFR) varies by age, gender, and body size, but for most adults, a GFR over 90 mL/min/1.73 m^2 is considered normal or healthy. GFR declines with age. For example, individuals over 70 years may have values between 45 to 60 mL/min/1.73 m^2 and still be considered to have normal kidney function for their age group. Regular monitoring of GFR can help detect kidney health issues early.
FAQs & Answers
- What is considered a normal GFR for adults? A GFR over 90 mL/min/1.73 m² is generally considered normal or healthy for most adults.
- How does GFR change with age? GFR naturally declines as people age; for example, individuals over 70 may have a normal GFR between 45 and 60 mL/min/1.73 m².
- Why is monitoring GFR important? Regular monitoring of GFR helps detect early signs of kidney dysfunction and allows for timely intervention.
- Can a lower GFR indicate kidney disease? Yes, a significantly lower GFR than expected for age may indicate impaired kidney function or kidney disease.
