Why the study?
What biochemical analytes should be measured in pleural fluid to identify the cause of a pleural effusion?
What biochemical analytes should be measured in pleural fluid to identify the cause of a pleural effusion?
Total protein performs as well as any single test for distinguishing exudate from transudate in pleural fluid, while specific tests like pH, glucose, and ADA are useful in specific clinical circumstances.
No takes yet. Share an insight, caveat, or question.
May guide initial pleural fluid testing toward total protein; leaves open optimal combinations for specific effusion etiologies.
Tarn et al. (2001) studied this question.
