Collection of cervical secretions for local immunological
assessment requires that the secretions be collected prior to the Pap
smear to avoid contamination with blood. The objective of the present
study was to determine whether gentle collection of cervical secretions
prior to a Pap smear collection influences the quality of the Pap
smear. A total of 266 women were recruited. Half of the participants
were assigned to collection of cervical secretions prior to Pap smear
collection with Weck-cel sponges. The remaining half had only the Pap
smear collection performed. Pap smear slides were reviewed and
evaluated for quality by the Bethesda System adequacy criteria without
knowledge of randomization. The proportions of limited or inadequate
slides in the two study groups were compared by using the Pearson
chi-square test. No significant differences were observed between the
two study groups when overall Pap smear quality was evaluated
(P = 0.29). Comparison of the two study groups with
respect to individual adequacy criteria, including presence of air
drying artifact, presence of obscuring blood, absence of metaplastic or
endocervical cells from the transformation zone, scant cellularity, and
presence of obscuring inflammatory cells, also revealed no significant
differences between the two study groups. Results from the present
study suggest that the collection of cervical secretions with Weck-cel
sponges does not adversely impact the quality of subsequently obtained
Pap smears.
