Plain-English summary
A study tested a new device called the OvaCyte Pet Analyser for detecting gastrointestinal parasites in dogs using fecal samples. This device showed very high sensitivity, meaning it was good at finding parasites like roundworms and hookworms, often outperforming traditional methods like centrifugal flotation. While it was slightly less specific than some other tests, it still proved to be a reliable option for identifying infections. Overall, the OvaCyte device could help veterinarians better diagnose and treat dogs with parasitic infections.

Abstract
BACKGROUND: Companion animals are infected with a range of helminth and protozoan parasites which can have a significant effect on health and welfare. While several diagnostic techniques are available to detect parasitic infection, they all vary in sensitivity and specificity. This study aims to estimate the diagnostic performance of the OvaCyte™ Pet Analyser by comparing it with established benchmarks commonly used in reference laboratories. METHODS: A total of 141 canine faecal samples, containing at least one species of parasite after screening using double centrifugation, were tested using four index tests: centrifugal flotation (faeces weighing either 1 g or 2 g), passive flotation, and the OvaCyte™ technique. The true status of each sample was determined on the basis of the initial screening test and the aggregated result of the four index tests. Sensitivity and specificity were calculated for each of the four index tests. RESULTS: The OvaCyte™ Pet Analyser displayed high sensitivity ranging from 90% to 100% in detecting various parasite species in canines. Its sensitivity for roundworm and hookworm detection differed significantly from centrifugal flotation using 1 g and passive flotation techniques (P < 0.05). The OvaCyte™ demonstrated higher sensitivity in detecting Cystoisospora spp. (90%) and Capillaria spp. (100%) compared to all flotation methods (P < 0.001), though it showed slightly lower specificity than the other techniques. CONCLUSIONS: These results highlight the variability in sensitivity across different diagnostic methods, underscoring the importance of selecting the most reliable technique for accurate parasite detection in veterinary practice. However, the OvaCyte™ Pet Analyser exhibits an elevated level of sensitivity compared to other techniques.
