Overview
Diagnosis necessitates paracentesis (needle drainage of the ascitic fluid) and laboratory confirmation of ascitic neutrophils > 250/mm3.
Laboratory Findings
Laboratory tests, most importantly ascitic fluid analysis is required for confirmation of diagnosis of spontaneous bacterial peritonitis.
- Complete blood count and differential count are tested to confirm infection.
- Serum electrolytes , creatinine to asses the renal function.
- Liver function tests are to performed for evaluation of cirrhosis.
- Blood cultures may be useful in sepsis
- Urine culture to rule out asymptomatic bacteruria
