Pah increase will reach inulin clearance
Web171. When the secretion of para-aminohippuric acid (PAH) reaches the renal tubular transport maximum (T m), a further increase in plasma PAH concentration causes its clearance to do which of the following? (A) Increase in proportion to its plasma concentration (B) Approach glucose clearance asymptotically (C) Remain constant (D) … WebOnly when the plasma level is well below that required to reach Tm can such solutes be extracted efficiently from the blood perfusing the kidneys and their clearance approach the RPF. Since even at low concentrations, only about 90% of substances such as PAH are excreted in one pass through the renal circulation, their clearance is termed the effective …

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 … 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 WebA: An amount of drug or chemical in units of gemessen like as milligrams.
