Plain-English summary
A study found that a new test for detecting certain parasites in dog and cat feces is effective, especially in young animals. The test, called the Fecal Dx immunoassay, was shown to be accurate in identifying these parasites, with a high agreement rate compared to the traditional testing method. It was particularly useful for puppies and kittens under one year old, where the prevalence of infection was notably higher. This new test could help veterinarians diagnose infections more reliably in pets, leading to better treatment options.

Abstract
species that infect dogs and cats are ubiquitous, and oocysts can be found in the feces of both subclinically infected and sick animals. Most clinical cases are diagnosed in puppies and kittens <4-mo-old. We validated a high-throughput immunoassay (Fecal Dx immunoassay; Idexx), which uses 2 monoclonal antibodies to detectspp. coproantigen, using zinc sulfate centrifugal flotation (ZCF) as the reference method and samples from experimentally infected animals. This new genus-level coproantigen assay had equivalent sensitivity for at least 4 relevantspp.-,like,, and-with no observed cross-reactivity to other protozoal parasites (,,,) of companion animals. In comparison to ZCF, the immunoassay had a positive percent agreement of 88.5% (95% CI [86.1, 91.6]) and a negative percent agreement of 98.2% (95% CI [98.1, 98.2]). The prevalence ofspp. detected by ZCF was 1%; the prevalence identified through coproantigen testing was 2.7% (95% CI [2.6, 2.8]). Among puppies and kittens <1-y-old, the prevalence according to coproantigen testing was 7.4% (95% CI [6.6, 8.2]) for puppies and 8.2% (95% CI [7.7, 8.6%]) for kittens; the prevalence detected by ZCF was 3.6% (95% CI [3.0, 3.9]) for puppies and 2.9% (95% CI [2.4, 3.4]) for kittens. Our results validate ourcoproantigen immunoassay as specific, precise, and sensitive.
