Document: The copyright holder for this preprint . https://doi.org/10.1101/2020.03.31.20045401 doi: medRxiv preprint number of tests was more than the current report and took a long time. Although the nucleic acid test was negative or single-target positive, the low number of white blood cells and lymphocytes in laboratory tests, and GGO in the lungs by CT examination indicated SARS-CoV-2 infection. It can be seen that using RT-PCR as a nucleic acid test cannot completely rule out SARS-CoV-2 infection. There are several factors that may cause the negative results when troubleshooting sampling and transportation issues.
