Diagnostic tap is used for the following:

  • New-onset ascites - Fluid evaluation helps to determine etiology, differentiate transudate versus exudate, detect the presence of cancerous cells, or address other considerations
  • Suspected spontaneous or secondary bacterial peritonitis
  • Refractory ascites [9]
