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)
