A. Cervical cytology collection devices: (1) Plastic spatula A. Cervical cytology collection devices: (1) Plastic spatula. (2) Endocervical brush. (3) Plastic broom. B. Pap preparations. Conventional cervical cytology is prepared by smearing collected cells directly onto a glass slide with the collection device followed by immediate fixation (upper slide). Liquid-based cytology involves transfer of collected cells from the collection device into a liquid transport medium with subsequent processing and transfer onto a glass slide. Cells are distributed over a smaller area, and debris, mucus, blood, and cell overlap are largely eliminated, allowing computer-assisted screening (lower slide).
