WebDec 7, 2015 · Die PAH-Clearance eines gesunden Erwachsenen liegt zwischen 550 und 720 ml/min/1,73 m 2. Berechnung. Die Ausscheidung der p-Aminohippursäure (PAH) erfolgt durch glomeruläre Filtration (20-30 %) und tubuläre Sekretion (70 %). … WebThe resting RBF was also measured simultaneously by both RA and the para-aminohippuric acid (PAH) clearance method (C PAH). Post-exercise RBF was measured only by RA within 60 s of exercise, then again within 30 and 60 min of exercise on different days, since RBF can be measured successively only three times even with the use of 99 mTc-phytate.

WebUnder these conditions, the clearance of PAH approximates the effective renal plasma flow, ERPF. What is the difference between renal blood flow and renal plasma flow? Renal blood flow ( RBF ) is the volume of blood delivered to the kidneys per unit time. Renal plasma flow ( RPF ) is the volume of plasma delivered to the kidneys per unit time.
