Pah clearance
Web5. Note that the ERPF is equal to the clearance of PAH and that it underestimates the true renal plasma flow by approximately 10%. 6. The "normal value" of ERPF in a 70 kg human is about 625 ml/min. Since the PAH clearance underestimates renal plasma flow by about 10%, the true renal plasma flow (RPF) is about 700 ml/min. 7. WebThe clearance of PAH is constant and high at low plasma [PAH], below the T m PAH. Under these circumstances the blood that perfuses the secreting portions of the nephron is nearly completely cleared of PAH. Under these conditions, the clearance of PAH approximates the effective renal plasma flow, ERPF.
