Web24 de nov. de 2024 · Since the extraction ratio (ERPF/RPF) at low arterial PAH concentrations is not affected by age (92% in young and old subjects), PAH clearance can be used to reflect changes in renal blood flow with age. The ERPF decreases more rapidly than the GFR, resulting in an increase in the filtration fraction. Inulin and PAH and their … Web21 de mai. de 2024 · The normal PAH clearance has been found to average 625 ml/min. Since the glomerular filtration rate averages about 120 ml/min, this indicates that only about 120/625, or roughly 20%, of the renal plasma flow is filtered. The remaining 80% passes on to the efferent arterioles. Since filtration and secretion clear only the molecules dissolved …
