List of terms related to PAH clearance. Editor-In-Chief: C. Michael Gibson, M. Para aminohippurate clearance or PAH clearance is a method used in renal physiology to measure renal plasma flow , which, in turn, is a measure of renal function.

The urine flow V as also measured. Renal perfusion flow is then calculated by:. What in fact is calculated is the effective renal plasma flow eRPF. The renal extraction ratio of PAH is a normal individual is approximately 0.

This margin of error is generally acceptable considering the ease with which eRPF is measured. Template:WikiDoc Sources.
