Azostix‐reagent‐test® strips (Ames, Miles, Inc., Diagnostic Division, Elkhart, IN) were used to measure blood urea nitrogen values in blood samples from 125 dogs and cats at the North Carolina State University, College of Veterinary Medicine. Results of the tests were compared with standard serum urea nitrogen results. Sensitivity, specificity, and negative predictive values were high (86.4, 90.3, and 96.5%, respectively). Positive predictive value was low; 65.5% of the dogs and cats with elevated blood urea nitrogen values were correctly classified as abnormal. The test performs well when the prevalence of abnormal values is near 50%.
