PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate … See more The renal extraction ratio of PAH in a normal individual is approximately 0.92, and thus not exactly 1.0. Thus, this method usually underestimates RPF by approximately 10%. This margin of error is generally acceptable … See more • Renal blood flow See more • Renal Clearance Techniques See more

WebPara-aminohippuric acid (PAH) is a substance that is freely filtered by the glomeruli in the kidneys and secreted by the tubular cells into the tubular fluid. The secretion of PAH occurs primarily in the proximal tubule of the nephron and is facilitated by transporters located on the luminal surface of the tubular cells.
