Clinical records, laboratory results and CT images were reviewed for nine COVID-19 patients with initially negative RT-PCR detection.Results: Fever and cough were common, and one patient merely present gastrointestinal symptoms. Increasing CRP and decreasing ALB were showed in nearly half of the patients among negative detection and return to normal level after real time polymerase chain reaction (RT-PCR) results converted from positive to negative. Left lower lobe was affected nearly in all the patients. A patient received oxygen support timely according his high Mulbsta score.Conclusion: Our study elucidated on the clinical features of hospitalized patients with initially negative detection of SARS-CoV nucleic acid. Patient merely with symptoms associated with digestive system should be screened for COVID-19. CT scan and repeated RT-PCR are two powerful diagnostic tools. Mulbsta score assessing in the early stage enhances the confidence of severity evaluation in physician.Keywords: COVID-19, negative detection, clinical characteristic, laboratory finding, CT images features
