The "normal value" of ERPF in a 70 kg human is about 625 ml/min. Since the PAH clearance underestimates renal plasma flow by about 10%, the true renal plasma flow (RPF) is about 700 ml/min. 7.

Each substance has its own specific clearance that depends on its unique filtration characteristics. birmingham al united states time nowPara-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. 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. d and d 5e monk build
