About: Extraction ratio

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Extraction ratio is a measure in renal physiology, primarily used to calculate renal plasma flow in order to evaluate renal function. It measures the percentage of the compound entering the kidney that was excreted into the final urine. Measured in concentration in blood plasma, it may thus be expressed as: , where Pa is the concentration in renal artery, and Pv is the concentration in the renal vein.

  • Extraction ratio is a measure in renal physiology, primarily used to calculate renal plasma flow in order to evaluate renal function. It measures the percentage of the compound entering the kidney that was excreted into the final urine. Measured in concentration in blood plasma, it may thus be expressed as: , where Pa is the concentration in renal artery, and Pv is the concentration in the renal vein. For instance, para aminohippuric acid (PAH) is almost completely excreted in the final urine, and thus almost none is found in the venous return (Pv ~0). Therefore, the extraction ratio of PAH ~1. This is why PAH is used in PAH clearance to estimate renal plasma flow. (en)
