Azostix-reagent-tests(R) 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%.
使用Azostix试剂测试（R）试纸条（艾姆斯公司，迈尔斯公司诊断部，印第安纳州埃尔克哈特）测量北卡罗来纳州立大学兽医学院125只犬猫血液样本中的血尿素氮值。将测试结果与标准血清尿素氮结果进行比较。敏感性、特异性和阴性预测值较高（分别为86.4%、90.3%和96.5%）。阳性预测值较低，血尿素氮值升高的犬猫中65.5%被正确分类为异常。当异常值的患病率接近50%时，该测试表现良好。
