WebAug 1, 1999 · We determined the effect of postischemic injury to the human renal allograft onp-aminohippurate (PAH) extraction (EPAH) and renal blood flow. We evaluated renal function in 44 allograft recipients on two occasions: 1–3 h after reperfusion (day 0) and again on postoperative day 7. On day 0 subsets underwent intraoperative determination of … WebSo to measure true renal plasma flow, the amount of plasma that flows into the kidney, we can use para aminohippuric acid – or PAH. That’s because PAH isn’t made in the body, so a known amount of PAH can be injected into the body. PAH is also ideal because it doesn’t alter renal plasma flow in any way.
PAH Clearance - an overview ScienceDirect Topics
WebInulin and para-aminohippuric acid clearances, determined by the conventional method of continuous intravenous infusion with blood and urine sample collections, are the gold standards for estimating glomerular filtration rate and renal plasma flow, respectively. Creatinine clearance provides a reaso … WebJan 1, 2024 · PDF On Jan 1, 2024, DM Vasudevan and others published Chapter-25 Kidney Function Tests ... PAH clearance is a measure of renal . plasma ow.

Measurement of renal function in patients with chronic kidney disease
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 WebThe effective renal plasma flow (ERPF), as measured by quantifying para-aminohippuric acid (PAH) clearance, decreases from a mean of 649 ml per min during the fourth decade to a mean of 289 ml per min during the ninth decade. Since the extraction ratio (ERPF/RPF) at low arterial PAH concentrations is not affected by age (92% in young and old ...
