What is normal PAH clearance? - Studybuff

WebPara-aminohippuric acid (PAH) is a substance that is freely filtered by the glomeruli in the kidneys and secreted by the tubular cells into the tubular fluid. The secretion of PAH occurs primarily in the proximal tubule of the nephron and is facilitated by transporters located on the luminal surface of the tubular cells. WebPAH can be hard to diagnose because its symptoms could be caused by many other conditions. Your provider will perform a physical exam and talk with you about your symptoms and medical history. You’ll likely need many tests (including imaging tests and blood tests) to find out if you have pulmonary hypertension and if so, which form. Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate … See more The renal extraction ratio of PAH in a normal individual is approximately 0.92, and thus not exactly 1.0. Thus, this method usually underestimates RPF by approximately 10%.

WebThe clearance of PAH is constant and high at low plasma [PAH], below the T mPAH. 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.
