Plain-English summary
A group of dogs with urinary problems were tested for a bacterial infection in their urine using three different in-house tests: SediVue, RapidBac, and a standard urine culture. These tests helped determine if the dogs had bacteriuria (bacteria in the urine) before sending samples for more detailed lab testing. The results showed that all three tests were effective at ruling out infections, which can help veterinarians make quicker and more responsible treatment decisions. This means that pet owners can get timely care for their dogs without unnecessary treatments.

Abstract
OBJECTIVE: To evaluate the clinical utility of 3 in-house tests to screen for bacteriuria in dogs with urinary conditions: a computerized urine sediment analyzer (SediVue), a rapid immunoassay (RapidBac), and in-house urine culture. Accuracy of culture and antimicrobial susceptibility (C&S) results from submission of the positive in-house culture plate and a 24- to 48-hour refrigerated urine sample was also assessed. METHODS: Sterile urine samples from 101 client-owned dogs were used to evaluate sensitivity, specificity, positive predictive value, and negative predictive value of 3 in-house diagnostic tests to detect bacteriuria using C&S testing at a reference laboratory as the reference standard. For positive in-house culture plates, the plate and a 24- to 48-hour refrigerated urine sample were submitted to the reference laboratory for C&S testing and compared to the reference standard. RESULTS: The reference standard C&S was positive in 25 of 101 cases (25%). All 3 in-house diagnostic tests had high negative predictive values: SediVue was 89% (95% CI, 81% to 96%), RapidBac was 93% (95% CI, 88% to 99%), and in-house culture was 99% (95% CI, 96% to 100%). Positive predictive values were 89% (95% CI, 74% to 100%) for SediVue, 77% (95% CI, 61% to 93%) for RapidBac, and 86% (95% CI, 73% to 99%) for in-house culture. Culture and antimicrobial susceptibility results from submission of the positive in-house plates and refrigerated urine samples approximated the reference standard. CONCLUSIONS: SediVue, RapidBac, and in-house cultures performed well to rule out canine bacteriuria. CLINICAL RELEVANCE: Inexpensive in-house diagnostic tests can be used to screen for bacteriuria prior to submission of C&S testing, which promotes antimicrobial stewardship, responsible use of client resources, and access to veterinary care.
