结核感染T细胞斑点试验及抗结核抗体检测在结核诊断中的应用价值评价

摘要

目的 评价结核感染T细胞斑点试验和血清学结核抗体(TB-Ab)检测两种方法在结核辅助诊断中的性能.方法 回顾性分析2015年1月至2016年3月浙江大学附属第二医院医院就诊确诊为结核患者的结核感染T细胞斑点试验(T-SPOT.TB)及TB-Ab检测结果.结果 在112例结核患者中,101例T-SPOT.TB检测阳性,灵敏度为90.18%,32例TB-Ab检测阳性,灵敏度为28.57%.其中肺结核41例,40例T-SPOT.TB阳性,灵敏度为97.56%;18例TB-Ab检测阳性,灵敏度为43.9%.肺外结核71例患者中,61例T-SPOT.TB检测阳性,灵敏度为85.91%,14例TB-Ab检测阳性,灵敏度为19.7%.结论 T-SPOT.TB检测不受标本采集的影响,灵敏度高,T-SPOT.TB的各项综合评价指标均优于血清学结核抗体(TB-Ab),对活动性肺结核的辅助诊断具有较高价值.%Objective To evaluate the performance of T-SPOT.TB Test and serological tuberculosis antibody(TB-Ab) in tuberculosis-assisted diagnosis.Methods Patients were diagnosed as tuberculosis from 2015 January to 2016 March in the hospital.T-SPOT.TB and tuberculosis antibody detection were performed for those patients.Results In 112 cases of tuberculosis patients,101 cases of T-SPOT.TB test were positive and the sensitivity was 90.18%,32 cases of tuberculosis antibody detection were positive and the sensitivity was 28.57%.In 41 cases of pulmonary tuberculosis,T-SPOT.TB assay showed positive results in 40 patients and the sensitivity was 97.56%,tuberculosis antibody detection showed positive results in 18 patients and the sensitivity was 43.9%;in 71 cases of extrapulmonary tuberculosis,T-SPOT.TB assay showed positive results in 61 patients and the sensitivity was 85.91%,tuberculosis antibody detection showed positive results in 14 patients and the sensitivity was 19.7%.Conclusion T-SPOT.TB was superior to serological tuberculosis antibody(TB-Ab),and the diagnosis of active tuberculosis was higher,and the sensitivity of T-SPOT.TB was higher than that of T-SPOT.TB value.
