尿标本预处理:待检尿收集后4℃冰箱放置4 h,离心,取上清液检测,当日不能检测的标本则加入叠钠使浓度为0.02%,储存于冰箱待测。检测方法:正规法、简化法。检测结果: 一、真实性灵敏度即真阳性率为92.65%;特异度即真阴性率为89.50%;假阳性率为10.50%;假阴性率为7.35%;粗一致性为90.89%;调整一致性为90.88%;约登指数为0.8215;阳性试验预示值为87.5%;阴性试验预示值为93.88%。二、可靠性同一尿样重复检验7次,重现性100%,完全一致。615例尿样中TLC检测19例,GC检测29例,均获与HI检测一致的结果。
Urease pretreatment: Collect urine for 4 h at 4 ° C, centrifuge, and take supernatant to detect. On the day, specimens that can not be detected are added with sodium to make the concentration 0.02%, and stored in the refrigerator for further testing. Detection methods: normal method, simplified method. Test results: First, the true sensitivity of the true positive rate was 92.65%; the specificity of the true negative rate was 89.50%; false positive rate was 10.50%; false negative rate was 7.35%; crude consistency was 90.89%; consistency adjustment Was 90.88%; Youden index was 0.8215; positive predictive value was 87.5%; negative predictive value was 93.88%. Second, the reliability of the same urine test repeated seven times, reproducibility 100%, exactly the same. Among the 615 urine samples, 19 were detected by TLC and 29 were detected by GC. The results were consistent with those by HI.
