The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 ml/min/1.73m 2 in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases. After age 40, GFR decreases ...

A glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m 2 is considered normal without chronic kidney disease if there is no kidney damage present. Kidney damage is defined as signs of damage seen in blood, urine, or imaging studies which include lab albumin/creatinine ratio (ACR) ≥ 30. [ 62 ]
The primary cause of the lack of clarity surrounding the GFR levels that indicate hyperfiltration is their strong reliance on age. [12] Glomerular hyperfiltration has traditionally been characterized as an elevated whole-kidney GFR, or a GFR greater than two standard deviations above the mean GFR of healthy individuals.
Chronic kidney failure is measured in five stages, which are calculated using the person's GFR, or glomerular filtration rate. Stage 1 CKD is mildly diminished renal function, with few overt symptoms. Stages 2 and 3 need increasing levels of supportive care from their medical providers to slow and treat their renal dysfunction.
In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate (GFR) over the renal plasma flow (RPF). Filtration Fraction, FF = GFR/RPF, or =. The filtration fraction, therefore, represents the proportion of the fluid reaching the kidneys that passes into the renal tubules. It is normally about 20%.
Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.
Micrograph of proteinaceous material in Bowman's space, which is unspecific. It is present in about 5% of people aged over 60 years, [2] but also in for example hypertensive kidney disease. Measuring the glomerular filtration rate (GFR) is a diagnostic test of kidney function. [3] A decreased GFR may be a sign of kidney failure. [citation needed]
