About this study
Official title: Diagnostic Performance of an Antigen Test for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection (COVID-19)
A comparison of a direct antigen test for SARS-CoV-2 obtained by mid-turbinate swab with the reference standard rt-PCR test obtained by nasopharyngeal swab in outpatients with symptoms compatible with COVID-19.
Read the detailed description
This study plans to compare a direct antigen test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) obtained by mid-turbinate nasal swab with a reverse transcription polymerase chain reaction (rt-PCR) test obtained by nasopharyngeal swab (the current reference standard) in a population of patients with symptoms suggestive of COVID-19 for fewer than 5 days. Subjects whose physicians have already ordered an rt-PCR test at a Carilion testing center will be screened and recruited by phone during a required scheduling call. The study coordinator will describe the study by phone, and the subject will be consented when they arrive at the testing center. After consenting, a mid-turbinate swab direct antigen test will be obtained just prior to the ordered nasopharyngeal swab and any other ordered tests. The subjects will receive their rt-PCR test results through the usual channels of clinical notification. The subjects will not receive their nasal antigen results. The antigen test results will be analyzed in a batch process and the results entered into RedCap by the study staff. The rt-PCR results will be extracted from the Epic electronic health record using patient identifiers and paired with the corresponding antigen result for statistical analysis.

Questions about this trial
What is this clinical trial studying?
A study testing Quidel Sofia SARS Antigen FIA in people with Covid-19, run by Carilion Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 17 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of True Positives (time frame: 1 day). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04610489, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2021.
