Assessment of 12 qualitative RT-PCR commercial kits for the detection of SARS-CoV-2

Abstract

The emergence of the novel coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the late months of 2019 had the officials to declare a public health emergency leading to a global response. Public measurements rely on an accurate diagnosis of individuals infected with the virus by using real-time reverse transcriptase-polymerase chain reaction (RT-PCR). The aim of our study is to relate the fundamental clinical and analytical performance of SARS-CoV-2 (RT-PCR) commercial kits. A total of 94 clinical samples were selected. Generally, 400 µl of each respiratory specimen was subjected to extraction using ExiPrep 96 Viral RNA Kit. All kits master mix preparation, cycling protocol, thermocycler, and results interpretation were carried out according to the manufacturer's instructions of use and recommendations. The performance of the kits was comparable except for the LYRA kit as it was less sensitive (F = 67, p
