Comparison of analytical sensitivity of SARS-CoV-2 molecular detection kits

ObjectivesSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has had a significant impact on global public health systems, making nucleic acid detection an important tool in epidemic prevention and control. Detection kits based on real-time reverse transcriptase PCR (rRT-PCR) have been used widely in clinics, but their analytical sensitivity (limit of detection, LOD) remains controversial. Moreover, there is limited research...
