ORTIZ, Laura C; GARZON, Anderson O  and  RODRIGUEZ, Berardo J. Cytodiagnosis trends at the animal pathology laboratory of the University of Antioquia (Colombia). Rev Colom Cienc Pecua [online]. 2011, vol.24, n.2, pp.157-169. ISSN 0120-0690.

This retrospective study describes the cytology diagnoses conducted at the animal pathology laboratory of the University of Antioquia from years 1996 to 2009. Results were expressed as proportions. The studied traits were: animal species, cytological method used, affected system, and diagnosis. A total of 97.1% samples (1454/1497) corresponded to canine species. Cytology swab was the most common diagnostic method (64.6%, 939/1454). The female reproductive tract was the most affected system (45.6%, 663/1454). The most frequent diagnosis was inflammation (30.9%, 449/1454). A high proportion of samples failed to establish a specific diagnosis (21.3%, 309/1454). It is concluded that cytology was very useful for the diagnosis of inflammatory processes. The high proportion of non-specific diagnosis was mainly due to inadequate extraction and delivery of samples. This suggests there is a lack of knowledge on sample selection criteria, as well as sampling and delivery procedures necessary to confirm the clinical diagnosis. This article discusses the main difficulties found for proper cytology diagnosis in our region and proposes alternatives to optimize its results.
