Effective renal plasma flow (eRPF) is a measure used in renal physiology[1] to calculate renal plasma flow (RPF) and hence estimate renal function.
Where extraction ratio is the ratio of compound entering the kidney that got excreted into the final urine.
When using a compound with an extraction ratio near 1, such as para-aminohippurate (PAH), then eRPF is almost equal to RPF. Therefore, PAH clearance is a method to estimate renal plasma flow.
