Effective renal plasma flow (eRPF) is a measure used in renal physiology to calculate renal plasma flow (RPF) and hence estimate renal function.

e R P F = R P F × e x t r a c t i o n   r a t i o

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.
