Answer

The fluid in bacterial peritonitis generally demonstrates a low pH and low glucose levels with elevated protein and LDH levels. Traditionally, ascitic fluid pH of less that 7.34 was consistent with a diagnosis of SBP; however, ascitic pH is less commonly measured because it is unreliable and lacks specificity for the condition.
