Our cytology department uses a technique that involves coating a centrifuge tube with Celloidin then spinning the sample in that tube. The cellodin is then scored and the "bag" of celloidin containing the cell button is taken out and wrapped in paper to be processed in a cassette. It is a tricky and a bit time consuming, but no material is lost in processing. We do up to 10 samples a day that way.

We seem to be retaining more specimen with that method (we have used sponges and lens paper in the past). Michael J.

We currently spin, pour off the supernatant, retrieve the sediment and process in lens paper. Does anyone have a more current technique which renders better cellularity? Also, do you know which renders a better cell block: a fresh specimen, a specimen fixed in Cytolyt or a specimen fixed in 10% NBF?
