Plain-English summary
A group of 24 dogs showing signs of a urinary tract infection (UTI) had their urine tested using a quick dipstick test to check for bacteria. The results showed that the dipstick test was very accurate, correctly identifying 89% of the dogs with a UTI and having no false positives. This rapid test could help vets diagnose UTIs more quickly and affordably compared to traditional urine cultures. While more studies are needed, this dipstick test shows promise for helping dogs with urinary issues.

Abstract
BACKGROUND: Bacterial urine culture is recommended in dogs suspected of having urinary tract infection (UTI), but there is expense and delay in obtaining such results. HYPOTHESIS/OBJECTIVE: To determine the diagnostic performance of a rapid immunoassay (RIA) dipstick for detection of bacteriuria using voided urine from dogs with clinical signs of lower UTI. ANIMALS: Twenty-four client-owned dogs. METHODS: Voided urine was collected and the RIA performed within 30 minutes. Urine collected by cystocentesis was submitted for aerobic urine culture. McNemar's test and kappa coefficient were calculated to determine agreement between the 2 tests. RESULTS: Nine of 21 dogs (43%) had UTI verified by aerobic urine culture. There was 1 false-negative and no false-positive RIA results. Sensitivity, specificity, positive predictive value, and negative predictive value of the RIA were 89%, 100%, 100%, and 92%, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: This RIA is promising for correctly identifying whether or not voided urine samples from dogs with lower urinary tract clinical signs have true bacteriuria in a rapid, inexpensive manner. Additional patients should be enrolled in a similar study to determine if diagnostic performance is robust in a large population.
