Quizplus · Accepted Answer

Pleural fluid pH is valuable in the diagnosis of esophageal rupture as it can show a pH<7.2, indicating the presence of gastric contents which have leaked into the pleural space from the ruptured esophagus. Ascitic fluid pH and ascitic fluid amylase are not useful in the diagnosis of esophageal rupture. Pleural fluid amylase can be elevated in cases of esophageal rupture, but it is not specific for the diagnosis and can also be elevated in other conditions such as pancreatitis.
