Making smears from fluids

This video outlines how to make classic “wedge-type” or blood smear-type smears or “contact” smears of body cavity fluids and joint fluids. These types of smears are standard for cytologic assessment and can also be used if liquid samples are aspirated from other sites, such as skin or internal cystic or cavitated lesions.
