Type of Preparation: Conventional Magnification: Low Adequacy Description: Squamous cellularity~150 cells in this 4X field Cytomorphologic Criteria: This image was composed to depict the appearance of a 4X field with approximately 150 squamous cells. It is to be used as a guide in assessing squamous cellularity of conventional specimens. An adequate conventional smear has an estimated minimum of approximately 8,000-12,000 well visualized and preserved squamous cells. Explanatory Notes: If all fields have this level of cellularity the specimen will meet the minimum cellularity criterion, but by only a small margin. This image illustrates the minimum average 4X field cellularity for conventional smears (assuming all fields are similar.).
