The Metrix Respiratory Panel Test will be evaluated for use in Non-Laboratory settings in a home testing environment utilizing the clinical study design described herein. The study will take place in simulated home environments which will be set up within or near active clinical settings (e.g., urgent care facilities). This will be a prospective study conducted at three or more investigational sites located within the United States for the clinical validation of the Metrix Respiratory Panel Test for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory syncytial virus, and Rhinovirus in anterior nares (AN) swab samples. Additional sites may be added to the study in order to meet minimum subject/sample enrollment requirements and geographic prevalence of respiratory virus infections. Comparator testing will be performed to determine the infection status of each sample for comparison to results generated by the candidate test. The primary comparator for the study will be an FDA-cleared assay for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory Syncytial Virus, and Rhinovirus.

The Metrix Respiratory Panel Test will be evaluated for OTC use in a home use testing environment utilizing the clinical study design described herein. The study will take place in simulated home environments which will be set up within or near active clinical settings (e.g., urgent care facilities). This will be a prospective study conducted at three or more investigational sites located within the United States for the clinical validation of the Metrix Respiratory Panel Test for the differential detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory syncytial virus, and Rhinovirus in AN swab samples. Additional sites may be added to the study in order to meet minimum subject/sample enrollment requirements and geographic prevalence of respiratory virus infections. Comparator testing will be performed to determine the infection status of each sample for comparison to results generated by the candidate test. The primary comparator for the study will be an FDA-cleared assay for detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory syncytial virus, and Rhinovirus.

The candidate device, Metrix Respiratory Panel Test, will be evaluated with AN swab sample types. Each Metrix Respiratory Panel Test kit contains all supplies needed to test AN swab samples, including a corresponding QRI for detailed instructions.

This OTC study will take place in simulated home environments which will be set up within or near clinical settings (e.g., urgent care facilities). The study will enroll symptomatic subjects only. Candidate samples will be self-collected by participants (or collected by a guardian for participants under the age of 14 years) and comparator samples will be collected by a healthcare practitioner with informed consent and Institutional Review Board (IRB) approval. Each sample will be coded for confidentiality.

For each participant, a comparator NP swab sample will be obtained by a healthcare practitioner after testing with the candidate device. This NP swab will be tested with the FDA-cleared SARS-CoV-2 assay according to the IFU and will serve as the primary comparator for swab samples. An additional AN swab sample will be collected and stored frozen and dry for later analysis to support future research validation studies.

No results from the investigational test or comparator testing will be used for clinical diagnosis, management of study participants, or to make treatment decisions.

Test results from the Metrix Respiratory Panel Test (investigational test) will be compared to the test results generated from the comparator assay.

No investigational test results will be used for any treatment decisions.
