Common Equations Used In Renal Physiology Name Equation Units Comments Clearance C x = [U] x V [P] x ml/min x is any substance Clearance Ratio Clearance Ratio = C x C inulin None Also means fractional excretion of x Renal plasma flow RPF = [U] PAH V [RA] PAH - [RV] PAH ml/min Effective renal plasma flow Effective RPF = [U] PAH V [P] PAH ml/min Underestimates RPF by 10% Equals C PAH Renal Blood Flow RBF = RPF 1 - Hct ml/min 1 - Hct is fraction of blood volume that is plasma Glomerular Filtration Rate GFR = [U] inulin
