    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    TaqPath™ test is more suitable performing a small number of tests at a time meanwhile the cobas® test should be more useful when it is necessary to analyze high amounts of samples The present study has some limitations. First, the intrinsic analytical variability of PCR can have influenced in the results obtained. Another limitation is the type of sample used in this study. Although serum samples are accepted in the analysis of viraemias, the common samples used in most microbiology laboratories are plasma samples. In conclusion, this study shows that cobas® SARS-CoV-2 Test and TaqPath™ COVID-19 CE-IVD RT-PCR Kit could be useful in SARS-CoV-2 viraemia detection in serum of diagnosed COVID-19 patients. For a better test performance, considering the detection of at least one target obtained with any technique, and in particular with a Ct value under 37 with the TaqPath™ assay. A viraemia positive result may help in handling COVID-19 patients, due to the relationship between viraemia and bad prognosis and mortality recently reported (4, 15). In addition, these techniques are easy to incorporate in the Microbiology laboratory routine for SARS-CoV-2 diagnosis. Finally it could open new treatment strategies based on early COVID-19 treatment (15).

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
