Establishing diagnostic algorithms for SARS-CoV-2 nucleic acid testing in clinical practice. |
T2 |

Sentence |
denotes |
BACKGROUND: |
T3 |
105-252 |
Sentence |
denotes |
Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic. |
T4 |
253-393 |
Sentence |
denotes |
Our laboratory initially used a two-step molecular assay, first reported by Corman et al., for SARS-CoV-2 identification (the T-CDC method). |
T5 |
394-730 |
Sentence |
denotes |
As rapid and accurate diagnosis of COVID-19 is required to control the spread of this infectious disease, the current study evaluated three commercially available assays, including the TaqPath COVID-19 Combo kit, the cobas® SARS-CoV-2 test and the Rendu 2019-nCoV Assay kit, to establish diagnostic algorithms for clinical laboratories. |
T6 |
731-739 |
Sentence |
denotes |
METHODS: |
T7 |
740-1027 |
Sentence |
denotes |
A total of 790 clinical specimens, including nasopharyngeal swabs, throat swabs, sputum, saliva, stool, endotracheal aspirate and serum were obtained from patients who were suspected or already confirmed to have COVID-19 at the Taipei Veterans General Hospital from February to May 2020. |
T8 |
1028-1159 |
Sentence |
denotes |
These specimens were tested for SARS-CoV-2 using the different assays and the performance variance between the assays was analyzed. |
T9 |
1160-1168 |
Sentence |
denotes |
RESULTS: |
T10 |
1169-1399 |
Sentence |
denotes |
Of the assays we evaluated, the T-CDC method and the TaqPath COVID-19 Combo kit require lots of hands-on practical lab work, while the cobas® SARS-CoV-2 test and the Rendu 2019-nCoV Assay kit are fully automated detection systems. |
T11 |
1400-1655 |
Sentence |
denotes |
The T-CDC method and the TaqPath COVID-19 Combo kit showed similar detection sensitivity, however, the T-CDC method frequently delivered false positive signals for E and/or RdRP gene detection, thus increasing the risk of reporting false positive results. |
T12 |
1656-1867 |
Sentence |
denotes |
A manual test-based testing strategy combining the T-CDC method and the TaqPath COVID-19 Combo kit was developed, which demonstrated excellent concordance rates (>99%) with the cobas and Rendu automatic systems. |
T13 |
1868-2023 |
Sentence |
denotes |
There were a few cases showing discrepant results, which may be due to the varied detection sensitivities as well as targets among the different platforms. |
T14 |
2024-2099 |
Sentence |
denotes |
Moreover, the concordance rate between the cobas and Rendu assays was 100%. |
T15 |
2100-2111 |
Sentence |
denotes |
CONCLUSION: |
T16 |
2112-2265 |
Sentence |
denotes |
Based on our evaluation, two SARS-CoV-2 diagnostic algorithms, one focusing on the manual assays and the other on the automatic platforms, were proposed. |
T17 |
2266-2507 |
Sentence |
denotes |
Our results provide valuable information that allow clinical laboratories to implement optimal diagnostic strategies for SARS-CoV-2 testing based on their clinical needs, such as test volume, turn-around time, and staff/resource limitations. |
