Examination of the ascitic fluid provides useful clues to the diagnosis of Budd-Chiari syndrome, including the following:

  • Patients usually have high protein concentrations (>2 g/dL); this may not be present in persons with the acute form of the disease

  • The white blood cell (WBC) count is usually less than 500/µL

  • The serum ascites–albumin gradient is usually less than 1.1 (except in the acute forms of Budd-Chiari syndrome)
