Kidney Gfr Normal Range For Age

Patients with markers of kidney disease and an egfr 90 ml min 1 73m2 are classified as stage g1 and those with an egfr 60 90 ml min 1 73m2 as stage g2. Glomerular filtration rate gfr gfr or glomerular filtration rate shows how much blood your kidneys filter in 1 minute. In adults the normal egfr number is more than 90.

Stage description glomerular filtration rate gfr 1 kidney damage e g protein in the urine with normal gfr 90 or above 2 kidney damage with mild decrease in gfr 60 to 89 3a moderate decrase in gfr 45 to 59 3b moderate decrease in gfr 30 to 44 4 severe reduction in gfr 15 to 29 5 kidney failure less than 15.

Kidney gfr normal range for age.

In young adults it is approximately 120 ml min 1 73 m 2 and declines in normal individuals with age. A gfr of 60 ml min 1 73 m 2 is within the normal reference range for men 60 years and women 50 years. If creatinine goes up it s a bad sign. Gfr decreases progressively after the age of 40 years.

In a recent study the use of a threshold value of 60 ml min 1 73 m 2 independent of age was also questioned. See chart below for average estimated egfr based on age. Our data suggest that recommendations to define kidney disease must be changed. Normal gfr varies according to age sex and body size.

The formula to calculate gfr includes body size age sex and ethnicity. Gfr is the best measure of kidney function but both creatinine and gfr can be useful indicators of your kidney health. If gfr goes down it s a bad sign. In the united states chronic kidney disease ckd defined by reduced gfr 60 ml min per 1 73 m 2 or presence of kidney damage is very common in the elderly population.

Egfr declines with age even in people without kidney disease. In general a good gfr number is above 60 and a good creatinine number is below 1 2. Gfr number by age the normal range of kidney glomerular filtration rate is 100 to 130 ml min 1 73m2 in men and 90 to 120ml min 1 73m2 in women below the age of 40. A better way to measure kidney function is to estimate gfr with equations that use serum creatinine levels and some or all of the following variables.

Over 10 of prospective donors older than 60 years had a mgfr 60 ml min 1 73m 2 and our model suggests that the lower limit of the normal range for gfr drops to 60 ml min 1 73m 2 by the age of 50 and 55 years for females and males respectively meeting the gfr cut off in the current definition of chronic kidney disease ckd. The prevalence of ckd is estimated to be 46 8 percent in those older than 70 years 1. Importantly patients with an egfr 60 ml min 1 73m2 and no other markers of kidney disease should be considered as having normal renal function and not labelled as having ckd.
