dilation and curettage
in this method, cells are collected after they have been either spontaneously shed by the body ("spontaneous exfoliation"), or manually scraped/brushed off of a surface in the body ("mechanical exfoliation"). an example of spontaneous exfoliation is when cells of the pleural cavity or peritoneal cavity are shed into the pleural or peritoneal fluid. this fluid can be collected via various methods for examination. examples of mechanical exfoliation include pap smears, where cells are scraped from the cervix with a cervical spatula, or bronchial brushings, where a bronchoscope is inserted into the trachea and used to evaluate a visible lesion by brushing cells from its surface and subjecting them to cytopathologic analysis. after sampling, two main techniques can be used; conventional cytology and liquid-based cytology. with the latter, we place the sample in a liquid that is then processed and allows for further investigation to be made.
cytopathology
cytopathologic tests are sometimes called smear tests because the samples may be smeared across a glass microscope slide for subsequent staining and microscopic examination. however, cytology samples may be prepared in other ways, including cytocentrifugation. different types of smear tests may also be used for cancer diagnosis. in this sense, it is termed a "cytologic smear".









































cytopathology is frequently, less precisely, called cytology, which means "the study of cells".

there are two methods of collecting cells for cytopathologic analysis: exfoliative cytology, and intervention cytology.
