Early Diagnostic paracentesis (needle drainage of the ascitic fluid performed in < 72hrs) is recommended in all cirrhotic patients with ascites. Paracentesis reveals an ascitic fluid with a total white cell count of up to 500 cells/mcL, a high polymorphonuclear (PMN) cell count (250/mm3 more). Ascitic fluid analysis and culture must be performed before initiating antibiotic therapy by bedside inoculation of ascitIc fluid ≥ 10 mL into blood culture bottles. Ascitic fluid analysis is the gold standard for the confirmation of the diagnosis of<unk><unk>  peritonitis. Ascitic fluid culture is negative in up to 60% of patients with clinical manifestations of<unk><unk>  peritonitis (SBP). Therefore, the diagnosis of SBP is based on the neutrophil count, which reaches its highest sensitivity with a cutoff neutrophil count of > 250/mm3. Leukocytosis and acidosis may be present but are non-specific. If reasonable doubt still persists, an exploratory peritoneal lavage may be performed (e.g. in the case of trauma, in order to look for white blood cells, red blood cells, or<unk> .
