WebAug 8, 2024 · First, phosphate concentration in the glomerular filtrate is equal to that in the blood. Second, proximal tubules reabsorb 70% of the filtrated water by default , which causes a 3.33-fold increase in the concentration of the solutes. Third, phosphate reabsorption takes place almost exclusively in proximal tubules . Last, fractional excretion … WebNomogram for the calculation of renal tubular reabsorption of phosphate (TmP/GFR) from plasma phosphate concentration and the fractional reabsorption of phosphate (TRP). The 0´ 0± 2´ 0 scale is suitable for estimating values of TmP/GFR close to the normal range …
