Cervical cytologic specimens were obtained with a Cytobrush
(MedScand [USA], Inc, Hollywood, Fla) and spatula or with a Cervex-Brush (Unimar, Inc, Wilton, Conn).
Cytologic specimens were obtained using an endocervical Cytobrush
and wooden spatula.
All cervical smears were taken using the Cytobrush
and Ayre spatula method except in pregnant women, on whom a swab and spatula was used. Slide preparation was performed by nurses assisting the physician, although some women physicians prepared their own slides when a nurse chaperone was not present.
A Papanicolaou smear was obtained from each subject by sampling the endocervix with a Cytobrush
and scraping the ectocervix with a wooden spatula.
A range of improved sampling instruments for collecting smears, including some specifically designed for sampling the endocervical canal (ie, Cytobrush
, Cervex-Brush), have become available.
Adequate sampling of cervical epithelial cells from the transformation zone is imperative for accurate cytopathologic interpretation.[1-3] Papanicolaou smear collections have been accomplished using various combinations of the traditional Ayre spatula, the Cytobrush
, and cotton-tipped applicators, with differing results.[3-7] The appropriate use of a well-designed cervical cytologic collection device may potentially reduce the complications of incomplete sampling.
Then a Papanicolau smear was repeated using a Cytobrush
for endocervical samples and plastic spatula for ectocervical smears.
These low rates were improved by a new sampling device, the cytobrush
. [1-4] A year later, because of its superior effectiveness in collecting cellular elements, we switched to the new cytobrush
as a sampling method.
Most providers used a blind swab of the anal canal with either a bristled cytobrush
or Dacron-tipped swab, and placed it directly into a ThinPrep jar (Cytyc, Marlborough, Massachusetts).
Papanicolaou smears were collected from the ectocervix and endocervix using an Ayres spatula and cytobrush
