Background: Studies evaluating the potential impact of photographer experience or the number of images evaluated using the "store-and-forward" method of telecytology are not reported., Objectives: This study aimed to determine the diagnostic sensitivity (Se) and specificity (Sp) of static telecytology when images were taken by experienced and inexperienced cytologists and when the number of images taken varied. Clinical agreement between the diagnoses was compared., Methods: Fifty archived cytology cases were randomly chosen. A board-certified clinical pathologist and a recent veterinary graduate took five images of each case. A third pathologist made a preliminary diagnosis after reviewing two images, and a final diagnosis after reviewing all images. The gold standard for comparison was the glass slide cytologic diagnosis., Results: Se and Sp were higher for the experienced cytologist and the evaluation of more images, but differences were not statistically significant. Clinical agreement between the image and glass slide diagnoses was significantly higher when images were taken by an experienced rather than inexperienced cytologist after the evaluation of two (P = .007) and five images (P = .008). The telecytology diagnoses agreed with the gold standard diagnoses more frequently after evaluation of five images rather than two when images were captured by both the experienced (P < .001) and inexperienced cytologist (P < .001)., Conclusions: There is more clinical agreement when the photographer has more cytology experience and when more images are provided for interpretation., (© 2019 American Society for Veterinary Clinical Pathology.)
