NCT04839094

Brief Summary

Saliva sampling could serve as an alternative non-invasive sample for SARS-CoV-2 diagnosis while rapid antigen testing (RAT) might help to mitigate the shortage of reagents sporadically encountered with RT-PCR. Thus, in the RESTART study the investigators compare antigen and RT-PCR testing methods on nasopharyngeal (NP) swabs and salivary samples. The investigators conducted a prospective observational study among COVID-19 hospitalized patients between 10th December 2020 and 1st February 2021. Paired saliva and NP samples were investigated by RT-PCR (Cobas 6800, Roche-Switzerland) and by two rapid antigen tests: One Step Immunoassay Exdia® COVID-19 Ag (Precision Biosensor, Korea) and Standard Q® COVID-19 Rapid Antigen Test (Roche-Switzerland).

Study Population

All hospitalized patients with a confirmed SARS-CoV-2 infection will be screened for inclusion criteria.

You may qualify if:

  • Hospitalized patients aged above 18 years with confirmed SARS-CoV-2 infection by RT-PCR assay.
  • Provide informed consent.

You may not qualify if:

  • Patient's refusal to participate in the study.
  • Patients with negative RT-PCR if already performed for patient's follow up as part of standard care.
