    Snippet: This study provides new theoretical basis for diagnosis on COVID-19, especially under the circumstance that there is relatively high false negative rate of nucleic acid RT-PCR test, and the time period from symptom onset to disease test detectable can be long, this study's result is of great reference significance. This study's result is helpful for early diagnosis, early isolation and early treatment of the patients, and can also play an importa.....
    Document: This study provides new theoretical basis for diagnosis on COVID-19, especially under the circumstance that there is relatively high false negative rate of nucleic acid RT-PCR test, and the time period from symptom onset to disease test detectable can be long, this study's result is of great reference significance. This study's result is helpful for early diagnosis, early isolation and early treatment of the patients, and can also play an important role in better epidemic control. However, this study has certain limitations. Firstly, this study's sample size is limited, which may lead to some bias in the research result. Secondly, this study only studies on patient's chest CT results before hospitalization, blood routine test results and first routine laboratory test results after hospitalization. Other indicators that may have diagnostic value for early diagnosis might be missed. Thirdly, previous research (15) shows few patients can have longest time period of 38 days from symptom onset to nucleic acid tested positive.
