Procurement and Storage of Pleural and Peritoneal Fluids for Biobanking

There is limited information regarding the biobanking of pleural and peritoneal fluids that might supplement storage of pulmonary and thoracic tissue biospecimens. Such fluids are sometimes collected for clinical analyses and may have uses that obviate or supplement tissue samples. There has been a growing interest in using liquid biopsies as they are less invasive and may be amenable to analyses that guide targeted therapies. Integrating cytology and biobanking approaches, we describe techniques that may be used for collecting and banking pleural and peritoneal fluids.
