What kind of specimens are typically prepared using a sediment smear?

Sediment smears are particularly useful for evaluating effusions from body cavities or bronchial washings. In these cases, the specimen often contains a variety of cell types and potentially pathogenic organisms that can be identified upon examination. The process involves centrifuging the fluid to concentrate the cells and debris at the bottom of the tube, which can then be smeared onto a microscope slide for further analysis.

This technique is especially relevant in the context of clinical diagnostics, as it helps in identifying infections, inflammatory processes, or malignancies present in bodily fluids. By preparing a sediment smear of effusions, laboratory professionals can also assess cellular characteristics and densities, providing crucial information for diagnostic purposes.
