Does liquid-based cytology improve smear-taking performance in an ordinary
clinical setting?

Liquid Based Cytology (LBC) has demonstrated its applicability to a national
screening programme. In trial settings, there is a reduction in unsatisfactory
smears compared with conventional cytology. This audit demonstrates the changes
to cytology results shortly after the introduction of liquid-based cytology in a
non-trial clinical setting in a busy sexual & reproductive health clinic.
These results were consistent for individual smear takers, although numbers of
smears taken in each time period were small for some staff. This audit shows
that expected changes to cytology results were obtained, and that staff did not
require a long time to learn to take smears successfully using the new technique.
