The Bayer Multistix are commonly used for detection and estimation of feline glucosuria by veterinarians and cat owners. A newer product, the Purina Glucotest, utilizes the same enzymatic technology for detection of glucose, but has been designed for home use as a litter additive that allows interpretation of glucosuria over an 8-h period. The objectives of this study were to assess the sensitivity, specificity, and accuracy of the Glucotest and Multistix, and to assess the 8-h color stability of the Glucotest. Overall, the Glucotest had greater sensitivity and specificity than the Multistix, and more accurately estimated urine glucose concentration if evaluated at least 30 min after exposure to urine. A significant lack of agreement between the results obtained immediately after exposure to urine vs after 30 min and 8 h contradicts the 8-h color stability claim, but the change in urine glucose concentration estimation over time resulted in improved test accuracy at the 30 and 480 min time points.
拜耳多试纸条被兽医和猫主人广泛用于检测和评估猫的糖尿情况。一种更新的产品，普瑞纳血糖测试条，采用相同的酶技术来检测葡萄糖，但它被设计为一种猫砂添加剂，供家庭使用，可在8小时内解读糖尿情况。本研究的目的是评估血糖测试条和多试纸条的敏感性、特异性和准确性，并评估血糖测试条的8小时颜色稳定性。总体而言，血糖测试条比多试纸条具有更高的敏感性和特异性，并且如果在接触尿液至少30分钟后进行评估，能更准确地估计尿葡萄糖浓度。尿液接触后立即获得的结果与30分钟和8小时后获得的结果之间存在显著差异，这与8小时颜色稳定性的说法相矛盾，但随着时间推移尿葡萄糖浓度估计的变化在30分钟和480分钟时间点提高了测试准确性。
