(The glomeruli are microscopic bundles of blood vessels inside nephrons, and are crucial parts of the filtering system.) This calculation is known as your estimated glomerular filtration rate (eGFR). Basically, it measures how much blood passes through the glomeruli each minute. Changing glomerular filtration rate. Standard inulin clearance studies performed by Guignard and co-workers 32,34,64 on the first 2 days of life indicated that GFR related to the body surface area increases rapidly from the 28th to the 35th week of gestation (Fig. Glomerular filtration in the nephron.

Knowing your GFR score enables your physician to figure out the stage of your kidney disease and plan the best possible treatment. Glomeruli are the tiny filters in the kidneys that filter waste from the blood. Glomerular filtration rate is an expression of the quantity of glomerular filtrate formed each minute in the nephrons of both kidneys, usually measured by the rate of clearance of creatinine. The glomerular filtration rate can't be measured directly -- that's where measuring creatinine and creatinine clearance comes in. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health.

Glomerular filtration rate (GFR; Estimated GFR; eGFR) is a test used to check how well the kidneys are working.Particularly, it approximates how much blood passes through the glomeruli each minute. The kidneys receive 20% to 25% of the cardiac output (about 1.0 to 1.1 liters per minute) with the blood entering individual glomerular tufts via the afferent arteriole and exiting through the efferent arteriole. Normal GFR varies according to age, sex, and body size, and declines with age. Jean-Pierre Guignard, in Fetal and Neonatal Physiology (Third Edition), 2004.
