Objectives:
Cytology is a quick, inexpensive, minimally invasive and widely available diagnostic method, but rigorous cooperation between clinical cytopathologist and physician is necessary to obtain clinically useful results. The aim of this study was to identify factors that affect clinical usefulness of a cytological result when the cellular material was collected by a general veterinary practitioner and examined by a clinical cytopathologist.
Materials And Methods:
Analysis of 100 fine-needle aspirates performed by private veterinarians and examined by the clinical cytopathologist. Factors dependent on a general veterinary practitioner who performed the biopsy such as comprehensiveness of a cover letter, number of smears sent and macroscopic appearance of smears, were included in the analysis. Patient species and location of the lesion were also included.
Results:
Only two factors turned out to favour a cytological diagnosis: good macroscopic appearance of smears and superficial location of the lesion. Nevertheless, inclusion of the medical history of a patient in a cover letter proved to help a clinical cytopathologist make clinically useful suggestions.
Clinical Significance:
Preparation of good quality smears and provision of a comprehensive cover letter will increase the likelihood of obtaining clinically useful cytological reports.
