what is normal gfr for age

The normal glomerular filtration rate (GFR) varies according to age, sex, and body size. In young adults, it is approximately 120 ml/min/1.73 m^2 and declines with age in normal individuals. In adults, the normal eGFR number is usually more than 90, and eGFR declines with age, even in people without kidney disease. Below 60 for three months or more means you have kidney disease, and a GFR of 15 or below means you have end-stage kidney failure. A GFR of 60 ml/min/1.73 m^2 is within the normal reference range for men over 60 years and women over 50 years52697-5/fulltext). Therefore, the normal GFR for age can be determined using the provided age-specific reference values and the decline in GFR with age.
