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 is excreted into the final urine.
When using a compound with an extraction ratio near 1, such as para-aminohippurate (PAH), eRPF approximates RPF. Therefore, PAH clearance can be used to estimate RPF.
