About this study

Official title: Clinical Performance Evaluation of the VitaSIRO Solo™ SARS-CoV-2/Flu/RSV Assay

The purpose of this clinical trial is to demonstrate the clinical performance of the VitaSIRO solo™ SARS-CoV-2/Flu/RSV Assay in detecting SARS-CoV-2, Flu A, Flu B and RSV in symptomatic population. The primary aim is to determine the PPA/NPA against a comparator assay. The secondary aim is to determine the diagnostic sensitivity, specificity, PPV and NPV against the standard-of-care test. Each subjects will be asked to provide both nasal swab (NS) and nasopharyngeal swab (NPS) for testing purposes.

Read the detailed description

The study is designed as a multisite, observational, prospective study. Subjects will be prospectively recruited from the target population, specifically individuals displaying signs and/or symptoms of respiratory tract infections. Consent for participation will be obtained prior to any eligibility confirmation or sample collection. Subsequently, both nasal swab (NS) and nasopharyngeal swab (NPS) specimens will be collected from each subject. These specimens will be tested using both the VitaSIRO solo™ SARS-CoV-2/Flu/RSV Assay and the Cepheid Xpert Xpress CoV-2/Flu/RSV plus assay (comparator) to determine the Positive Percent Agreement (PPA) and Negative Percent Agreement (NPA).

Subjects will be recruited across up to 20 sites, targeting the following intended user groups:

Trained laboratory professionals in a central laboratory setting Trained healthcare practitioners in a point-of-care (POC) setting under CLIA moderate and high complexity.

If a standard-of-care (SOC) diagnosis is available, the sensitivity, specificity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) will also be calculated.

Questions about this trial

What is this clinical trial studying?

An observational study of SARS-CoV-2 and COVID-19, run by Credo Diagnostics Biomedical Pte. Ltd. at 1 site in Taiwan.

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 16 inclusion and 3 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: finished, as of the sponsor's last update on 18 Mar 2026. 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 Taiwan. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Positive percent agreement(PPA) and Negative percent agreement (NPA) (time frame: In 7 days after specimen collection). 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 NCT06689423, which also lists 1 linked publication.

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 18 Mar 2026.
