Diagnosis of SBP on Ascites Fluid Analysis

Standard Evaluation

  • 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

Consider Peritonitis (eg. perf appy, chole)

Any:

  • >10,000 WBC
  • Polymicrobial gm stain
  • Total protein >1g/dL
  • Glu <50
  • Increased LDH

If on Peritoneal Dialysis

SBP if:

  • >100WBC OR >50% NEUT

If on Nightly APD

SBP if:

  • >50%NEUT
  • Amylase (>100 suggestive of intra-abdominal process)
