To develop and trial a dried tube specimen (DTS) panel for proficiency testing of dual HIV/syphilis rapid diagnostic tests (RDTs) at clinical sites.
DTS panels were prepared using plasma samples with known HIV and syphilis results, to give varying reactivity for syphilis and HIV test lines on RDTs. Laboratory DTS panels were stable for a minimum 4-week period at ambient temperatures with no inter-reader variability of results. Field testing of panels with Standard Diagnostics Bioline HIV/Syphilis duo showed 100% correlation with laboratory results, and excellent mean pair agreement between the two clinical sites (k = 1.0). With Chembio Dual Path Platform HIV-Syphilis, there were two false negative results for HIV and syphilis, respectively, at one site; and good mean pair agreement between the two sites (k = 0.9).
It is feasible and practicable to incorporate DTS panels into a field proficiency testing scheme for dual HIV/syphilis RDTs.
开发并试用一种干试管标本(DTS)检测板,以对临床现场的双 HIV/梅毒快速诊断检测(RDT)进行能力验证。
使用已知 HIV 和梅毒结果的血浆样本制备 DTS 检测板,使 RDT 的梅毒和 HIV 检测线呈现不同的反应性。实验室 DTS 检测板在环境温度下至少稳定 4 周,结果无读者间差异。与 Standard Diagnostics Bioline HIV/Syphilis duo 检测板的现场测试显示,与实验室结果具有 100%的相关性,两个临床地点之间具有极好的平均配对一致性(k=1.0)。使用 Chembio Dual Path Platform HIV-Syphilis,一个地点的 HIV 和梅毒分别有两个假阴性结果;两个地点之间具有良好的平均配对一致性(k=0.9)。
将 DTS 检测板纳入双 HIV/梅毒 RDT 现场能力验证方案是可行和实用的。
