A normal glomerular filtration rate (GFR) varies based on age. While a GFR of 90 to 120 mL/min/1.73 m2 is generally considered normal for younger adults, this value declines with age. For example, a GFR of 60 mL/min/1.73 m2 is considered within the normal range for men over 60 years old and women over 50 years old. This age-related decline is a natural process and doesn't necessarily indicate kidney disease. However, a GFR below 60 mL/min/1.73 m2 for three months or more indicates kidney disease, and a GFR of 15 or below indicates end-stage kidney failure.
It's important to note that these are general ranges, and individual values may vary based on factors like gender, ethnicity, and overall health. If you have any concerns about your GFR, consult with a healthcare professional for personalized guidance.
