Studies were designed to assess the accuracy of urine glucose testing in a sample of juvenile diabetic subjects, and to determine the effects of a visual discrimination training procedure on the accuracy. In the first study, each of 81 juvenile-diabetic children was presented three prepared glucose solutions and asked to determine the glucose concentration using the 2-Drop Clinitest method. Results showed errors in 54.3% of the judgments, with greatest difficulty occurring with 1-g/dl concentrations. The majority of errors were false negatives. Study II involved similar testing accuracy on a sample of 10 nurses and 2 research technicians, before and after a visual discrimination training procedure. Results showed that the subjects were incorrect on 39% of the trials initially, with a reduction in the error rate to less than 19% after training.
研究旨在评估青少年糖尿病患者样本中尿糖检测的准确性，并确定视觉辨别训练程序对准确性的影响。在第一项研究中，向81名青少年糖尿病儿童每人提供三种配制好的葡萄糖溶液，并要求他们使用两滴Clinitest法测定葡萄糖浓度。结果显示，54.3%的判断存在误差，其中1克/分升浓度的判断难度最大。大多数误差为假阴性。研究二对10名护士和2名研究技术人员的样本在视觉辨别训练程序前后进行了类似的测试准确性研究。结果显示，受试者最初在39%的试验中判断错误，训练后错误率降至19%以下。
