"'''Other Tests'''
''The fluid can be assessed for glucose and lactate level. A sample with a glucose concentration higher than that of the peripheral blood indicates septic peritonitis. If the peritoneal lactate concentration is higher than the peripheral blood concentration then intestinal infarction is likely. Serum and peritoneal fluid creatinine levels can be measure in cases where uroperitoneum is suspected (peritoneal creatinine levels should be double than of plasma in these cases).''"

I am confused about the rationale behind the glucose from a septic tap being higher than peripheral blood. My understanding is that the bacteria in the exudate metabolises the glucose, causing it to be decreased when compared to blood levels. Is this a typo or am I being daft?
