Description:The three glass microscope slides depicted here. Illustrate the qualities of smear-thickness when preparing a fecal smear sample to be examined under the optics of a microscope. These three slide samples were unpreserved, and are seen here, prior to having undergone a staining procedure.
The top slide (A) yielded the correct smear thickness to be processed for examination, while the middle slide yielded an inadequately-thin smear preparation, and the bottom yielded an overly-thick smear preparation. Also, one need to take into account that more than one specimen should be examined in order to achieve a more accurate diagnosis.
