General description

Renal tubules secretes para amino hippuric acid/PAH.[1]

Application

p-Aminohippuric acid has been used as infusions to measure plasma flow.[2][3][4]

Biochem/physiol Actions

Para-Aminohippuric acid (PAH), OAT-1 specific, is used to help differentiate and characterized organic anion transporter (OAT) isoforms.
Para-aminohippuric acid (PAH) is used as a marker in nutrition studies to measure the flow of blood in pigs, which inturn helps to determine the portal-drained viscera (PDV) flux of nutrients.[5]
