Plain-English summary
A group of 40 dogs showing signs of a lower urinary tract infection (UTI) had their urine tested using a quick test that can be done right at the vet's office. The test was able to accurately detect bacteria in the urine, even if the samples were refrigerated for up to 24 hours. Out of the dogs tested, 14 were confirmed to have a UTI, and the rapid test correctly identified all of them. This method is not only fast but also cost-effective, making it a useful tool for diagnosing UTIs in dogs.

Abstract
OBJECTIVE: To collect voided urine from dogs with clinical signs of lower UTI and determine the diagnostic performance of a commercially available rapid immunoassay (RIA) immediately after urine collection and after refrigeration at 4 and 24 hours. ANIMALS: 40 client-owned dogs. METHODS: Aerobic urine culture was performed on urine collected by cystocentesis. Urine samples were collected by voiding, and the RIA performed in triplicate within 30 minutes (time 0) and again in triplicate after 4 and 24 hours of refrigeration. Test precision and agreement between culture results and RIA results at each time point were determined, and factors possibly associated with false results investigated. RESULTS: 14 of 40 dogs (35%) had UTI verified by aerobic urine culture, and all had positive RIA. Three dogs had false positive RIA results. Sensitivity, specificity, positive predictive value, and negative predictive value of the RIA were 100, 88%, 82%, and 100%, respectively, and results were not different after 4 and 24 hours of refrigeration. Precision was excellent. CLINICAL RELEVANCE: This point-of-care RIA, performed on voided urine refrigerated up to 24 hours, rapidly and accurately identifies bacteriuria in dogs with lower urinary tract clinical signs, inexpensively.
