Overview
Paracentesis is sampling ascites fluid through abdominal wall with overall complication rate of not more than 1%. The sampled fluid will be surveyed upon total protein concentration, neutrophil count, and inoculation into blood culture bottles.

Paracentesis
- Paracentesis is sampling ascites fluid through abdominal wall with overall complication rate of not more than 1%.[1]
- The sampled fluid will be surveyed upon:[2]
- Total protein concentration
- Neutrophil count
- Inoculation into blood culture bottles
- Paracentesis findings include:[3][4]
- Protein concentration <1.5 g/dL is predictive of high risk for spontaneous bacterial peritonitis (SBP)
- Neutrophil count of > 250 per mm3 is diagnostic of SBP
- Positive culture of ascites fluid is diagnostic of SBP
- Measuring serum-ascites albumin gradient (SAAG) is also helpful for diagnosing the underlying disease
