  2. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    The glomerular filtration rate (GFR) describes the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [3] Creatinine clearance (C Cr) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.

The list excludes large privately held companies such as Cargill and Koch ...

  4. Ultrafiltration (kidney) - Wikipedia

    en.wikipedia.org/wiki/Ultrafiltration_(kidney)

    In renal physiology, ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule (Bowman's capsule) in the kidneys. As in nonbiological examples of ultrafiltration, pressure (in this case blood pressure) and concentration gradients lead to a separation through a semipermeable membrane (provided by the ...

  5. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.

  6. Renal physiology - Wikipedia

    en.wikipedia.org/wiki/Renal_physiology

    This is performed at the microscopic level by many hundreds of thousands of filtration units called renal corpuscles, each of which is composed of a glomerulus and a Bowman's capsule. A global assessment of renal function is often ascertained by estimating the rate of filtration, called the glomerular filtration rate (GFR).

  7. Glomerulus (kidney) - Wikipedia

    en.wikipedia.org/wiki/Glomerulus_(kidney)

    The glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. [2] The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall kidney function, is the glomerular filtration rate.

  8. Glomerular hyperfiltration - Wikipedia

    en.wikipedia.org/wiki/Glomerular_hyperfiltration

    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.
