Test Us At Home Daily

Symptomatic or close-contact participants were enrolled and asked to perform daily tests for 10 days. Each participant performed a rapid antigen test (Quidel or Abbott) followed by home-based sample collection and subsequent highly sensitive RT-qPCR assay (Roche, LOD = 1,800 NDU/mL) performed in a CLIA-certified lab.招募有症状者及密切接触者作为研究受试者，要求其连续10天每日完成检测。每位受试者首先开展快速抗原检测（使用奎德 (Quidel) 或雅培 (Abbott) 试剂盒），随后进行居家样本采集；采集得到的样本将被送至临床实验室改进修正案 (CLIA) 认证实验室，采用罗氏 (Roche) 平台进行高灵敏度逆转录实时荧光定量聚合酶链反应 (RT-qPCR) 检测，该检测的检测限 (LOD) 为1,800 NDU/mL。
