The pH of ascitic fluid is a critical marker in Ascitic Fluid Biochemical Analysis, primarily used to detect Spontaneous Bacterial Peritonitis (SBP). In the presence of bacterial infection, the pH of the fluid drops due to increased anaerobic metabolism and lactic acid production. A pH below 7.35, particularly when the Serum-Ascites Albumin Gradient (SAAG) is also considered, is highly suggestive of an infected state.

Why Context Matters
The measurement is highly sensitive to specimen handling. Exposure to air or delay in transport to the lab can cause CO2 loss and an artificial rise in pH, potentially masking an infection. It must be interpreted alongside the Polymorphonuclear (PMN) cell count and fluid culture.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
