Serum B-type natriuretic peptide in the initial workup of patients with new onset ascites: A diagnostic accuracy study

Abstract

Serum BNP is more accurate than ascites analyses in the diagnosis of HF-related ascites. The workup of patients with new onset ascites could be streamlined by obtaining serum BNP as an initial test and could forego the need for diagnostic paracentesis, particularly in cases where the cause of ascites is uncertain and/or could be the result of HF.
