Diagnosis of SBP on Ascites Fluid Analysis

  • Paracentesis results supporting a diagnosis of SBP:
    • Total WBC >500
    • Absolute neutrophil count (PMNs) > 250
    • Bacteria on gram stain (single type)
    • SAAG > 1.1
    • Protein < 1, Glucose > 50 (otherwise concern for secondary bacterial peritonitis)

^For bloody tap, subtract 1 WBC for every 250 RBC
