Abstract
A method is described for preparing cervical scrape specimens for automated analysis on the Cerviscan prescreening system. In order to reduce the cellular clumping found in cervical scrape material, cells are collected in suspension, syringed to disaggregate the cell clumps, and then pipetted onto a glass to give a monolayer of cells. The cells are then stained with gallocyanin chrome-alum to give the required quantitation of nucleic acid content, using a rapid staining procedure. Experimental results are given which show that specimens prepared by this method are more suitable for automated analysis than the conventional Papanicolaou stained preparation.
