MYCOBACTERIUM TUBERCULOSIS (MTB) QUALITY ASSESSMENT PROGRAM (TBQA)

结核分枝杆菌（Mtb）质量评估计划（TBQA）的目的是提供一种新的资源，以评估位于美国（美国）和国外（非美国）的实验室准确可靠地进行结核分枝杆菌检测的能力，以诊断活动性和潜伏性结核分枝杆菌感染，监测疾病进展，并评估治疗反应和疫苗效力，直接支持临床试验。随着新测试/方法的开发，TBQA项目将在纳入niaid支持的临床研究之前促进其适应、标准化和质量评估。TBQA项目将为niaid资助和合作的临床试验网络和群组以及在美国境内外进行研究的个人受资助者提供服务。niaid资助的网络的例子包括成人艾滋病临床试验组（ACTG）、国际孕产妇、儿科和青少年艾滋病临床试验组（IMPAACT）和艾滋病毒疫苗试验网络（HVTN）。niaid资助的队列研究包括印度和巴西结核病区域前瞻性观察研究（报告）。合作用户组的例子包括疾病预防控制中心、全球结核病药物开发联盟和美国军方艾滋病毒研究计划。

The purpose of the Mycobacterium Tuberculosis (Mtb) Quality Assessment Program (TBQA) is to provide a new resource to assess the ability of laboratories located both in the United States (U.S.) and outside (non-U.S.) to accurately and reliably perform Mtb testing to diagnose active and latent Mtb infection, monitor disease progression, and assess treatment response and vaccine efficacy in direct support of clinical trials. As new tests/methodologies are developed, the TBQA program will facilitate their adaptation, standardization and quality assessment prior to inclusion in NIAID-supported clinical investigations. The TBQA program will serve NIAID-sponsored and collaborating clinical trials networks and cohorts as well as individual grantees conducting research in and outside the United States. Examples of NIAID-sponsored Networks include the Adult AIDS Clinical Trials Group (ACTG), the International Maternal Pediatric and Adolescent AIDS Clinical Trials Group (IMPAACT) and the HIV Vaccine Trials Network (HVTN). Examples of NIAID-sponsored cohorts include the India and Brazil Regional Prospective Observational Research for Tuberculosis (RePORT). Examples of collaborating User Groups include the CDC, the Global Alliance for TB Drug Development, and the US Military HIV Research Program. The TBQA contract will be responsible for monitoring Labs’ ability to perform accurately and reliably study-specified Mtb tests (e.g. next-generation bacterial DNA and RNA sequencing, serial sputum colony count on solid media, time to positivity in liquid culture, minimal inhibitory concentration assessment, and host-based assays). This will include preparation of proficiency testing panels (or acquisition from commercial and non-commercial sources), distribution to participating laboratories, capture and statistical analysis of test results obtained from Labs, determination of performance acceptability, and generation of Lab-specific performance reports. The TBQA will provide assistance, guidance and training in corrective action when Labs’ test performance is unacceptable.
