查询词典 specificity

The results showed that the virus isolation and identification could generate considerably reliable results but the procedure was complicated and costed long time; microtomy fluorescent antibody detection was fast, but the specificity was low and needed to exclude the false positive from the results. Sandwich ELISA detection combined the merits of the former two methods, but it generated the false negative results when the samples were in bad preservation. Compared with the others, RT-PCR was fast, high sensitive and especially useful for detecting the CSFV directly from the samples. The specificity could be raised by using the nested-PCR to detect the CSFV from the simples, especially when the simples were in bad preservation.

结果显示，病毒分离鉴定法准确性较高，诊断比较容易，但存在试验步骤繁琐，所需时间长的缺点；荧光抗体检测法所需时间较短，但需要经验比较丰富人员来判定结果，且存在假阳性结果，特异性比较差；RT-PCR检测法具有快速、敏感等优点，特别是样品保存不理想时更有价值，利用套式PCR可以提高检测的特异性；夹心ELISA检测法具有快速、敏感等优点，但在样品保存不理想时会出现假阴性结果。

The sensitivity and specificity of far-infrared thermography in the diagnosis of lumbar disc herniation were evaluated. Compared with the normal, the thermogram of twenty-three cases on low back with LDH changed. They can be divided into four thermal patterns that is shuttle-liking (8 cases), discontinued in the middle line (6 cases), large regional (5 cases) and nonregular (4 cases) pattern. The temperature of abnormal sides is lower than the counterpart in most cases (nineteen of twenty-three). The thermography diagnosed LDH with sensitivity 90.48% and specificity 66.68%.
