【摘 要】目的:探讨酶联免疫吸附法与甲苯胺红不加热血清试验法检测梅毒的价值。方法:选36例作为观察A组,另外36例梅毒患者作为观察B组。观察A采用酶联免疫吸附法(ELISA),观察B组使用甲苯胺红不加热血清试验(TRUST)检测。检测后,比较两组的敏感性、特异性、阴性预测值、阳性预测值指标。结果:观察A组使用检测的上述指标均明显高于观察B组,并且观察A组血清阳性率大于观察B组,P<0.05。结论:ELISA法对梅毒的敏感性强,在检测中表现出较高阳性率,在大量样本筛选中有突出优势。

【Abstract】Objective: To investigate the value of enzyme-linked immunosorbent assay (ELISA) and toluidine red non-heated serum test for the detection of syphilis. Methods: Thirty-six patients were selected as observation group A, and another 36 patients with syphilis were observed as group B. Observation A was measured by enzyme-linked immunosorbent assay (ELISA), and group B was observed using toluidine red unheated serum test (TRUST). After the test, the sensitivity, specificity, negative predictive value, and positive predictive value index of the two groups were compared. Results: The above-mentioned indicators of group A were significantly higher than those of group B, and the seroprevalence of group A was higher than that of group B, P<0.05. Conclusion: The ELISA method has strong sensitivity to syphilis and shows a high positive rate in the test. It has outstanding advantages in screening a large number of samples.

梅毒的傳播途径有多种,主要以性传播、母婴传播途径常见。这种疾病传染速度快、发病率高,找到快速有效的检测方法对疾病的治疗具有很好的疗效。本文通过对72例梅毒患者采用不同的检测方法,比较酶联免疫吸附法和甲苯胺红不加热血清试验对梅毒检验的应用,以下是详细报道。
1 资料与方法
1.1临床资料 将参与本次研究的72例患者根据数据表随机划分为观察A组、观察B组,每组36例患者,两组患者基本资料没有差异,P>0.05,两组患者基本资料具体见下表1。
1.2方法
观察A组:将患者的静脉血10 mL首先放置15 min,然后对其进行离心,分离后取血清进行ELISA检测。检测操作严格按照ELISA法说明书进行梅毒检测。
观察B组:将患者的静脉血10 mL首先放置15 min,然后对其进行离心,分离后取血清进行TRUST检测。检测操作严格按照ELISA法说明书进行梅毒检测。
1.3观察指标
1.3.1灵敏度、特异性、阳性及阴性 观察并记录灵敏度、特异性、阳性及阴性的变化情况。
1.3.2准确度 根据上述指标综合诊断两组的准确度,比较两种检测方法的准确度。……p>
