How is the gfr kidney measurement calculated
WebNFP determines filtration rates through the kidney. It is determined as follows: NFP = Glomerular blood hydrostatic pressure (GBHP) – [capsular hydrostatic pressure (CHP) + blood colloid osmotic pressure (BCOP)] = 10 mm Hg That is: NFP = GBHP – [CHP + BCOP] = 10 mm Hg Or: NFP = 55 – [15 + 30] = 10 mm Hg Web1 feb. 2001 · The GFR cannot be directly measured in humans, but can be estimated from urinary clearance of a substance (x), given by the equation: where U is the urinary concentration of an ideal filtration marker of x, V is the urine flow rate and P x is the average plasma concentration of x.

In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a 70-kg adult male.It passes about 94% to the cortex. RBF is closely related to renal plasma flow (RPF), which is the volume of blood plasma …
