Diagnostic value of amino acid consumption test on exocrine pancreatic insufficiency

Amino acid consumption test (AACT) has a high sensitivity and specificity in evaluating exocrine pancreatic insufficiency[1,2], but its diagnostic value to exocrine pancreatic insufficiency in Chinese has not been well understood. In this study, the oral reagent stimulating pancreatic secretion (O-AACT) was used instead of cerulein (I-AACT) for amido acid consumption test and the dignostic efficiency of O-AACT was evaluated and compared with I-AACT on the exocrine pancreatic insufficiency in Chinese.
