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 … WebPara aminohippurate clearance or PAH clearance is a method used in renal physiology to measure renal plasma flow, which, in turn, is a measure of renal function . The concentration of para aminohippurate (PAH) is measured in one arterial blood sample (P PAH) and one urine sample (U PAH ). The urine flow (V) as also measured.

WebPAH is also used to measure the functional capacity of the renal tubular secretory mechanism or transport maximum (Tm PAH). This is accomplished by elevating the plasma concentration to levels (40-60 mg/100 mL) sufficient to saturate the maximal capacity of the tubular cells to secrete PAH. Inulin clearance is generally measured during Tm. PAH
