Para-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. WebNet PAH secretion is restricted to PTC cell monolayers and is sensitive to inhibition by excess PAH. The data are expressed as the mean ± SEM of 4 monolayers per condition …
