Body Cavity Effusion Fluids for Cytology
Pleural fluids, ascitic (peritoneal) fluids and pericardial fluids should be put into special 120 ml effusion specimen containers. These containers are available from the Cytology laboratory. This volume allows adequate cellular material for all cytological testing, including preparation of cell blocks for immunohistochemical testing.
Large volumes of effusion fluids in drainage bags and bottles are difficult for the laboratory to handle, are not necessary, and are not encouraged.
