Title: FALSE-NEGATIVE RESULTS OF INITIAL RT-PCR ASSAYS FOR COVID-19: A SYSTEMATIC REVIEW Document date: 2020_4_21
ID: g8h6trql_14
Snippet: We included observational studies (including accuracy studies, cohorts, and case series) reporting 115 the initial use of RT-PCR to the detection of SARS-CoV-2 RNA in patients under suspicion of infection 116 by clinical or epidemiological criteria. Specially, we prioritised studies enrolling consecutive patients 117 who were receiving RT-PCR as initial testing with further confirmation of SARS-CoV-2 infection 118 and/or COVID-19 diagnosis (posit.....
Document: We included observational studies (including accuracy studies, cohorts, and case series) reporting 115 the initial use of RT-PCR to the detection of SARS-CoV-2 RNA in patients under suspicion of infection 116 by clinical or epidemiological criteria. Specially, we prioritised studies enrolling consecutive patients 117 who were receiving RT-PCR as initial testing with further confirmation of SARS-CoV-2 infection 118 and/or COVID-19 diagnosis (positive/negative). We did not impose limits by age, gender, or study 119 location. 120
