The Effects of Plural Fluid on Prognosis

You don't need to compare to a simultaneous serum assessment of these assays, and so you can just use the plural fluid studies. And there's good evidence that suggests that it has similar sort of diagnostic profile or performance compared to light criteria in distinguishing trans-days and exodates. The other thing that I would add to that would be to send fluid off in blood culture bottles. This isn't something that all hospitals do, and it took about five years for us to get that done.
