Performance of the LumiraDx SARS-CoV-2 Ag assay will be assessed by comparison to a reference method.

The study is a prospective, multi-center study. One (1) reference laboratory and approximately six (6) geographically diverse POC (Point of Care) locations (e.g. physician office laboratories, urgent cares, emergency departments, outpatient clinics, drive through testing sites or research centers) in the U.S. will participate in the study. Testing in the reference laboratory will be performed by trained laboratory personnel. Testing at the POC sites will be performed by non-laboratory health professionals who are representative of typical intended use operators (e.g. nurses, physician assistants, medical assistants, etc.). Each site will have a minimum of one (1) untrained intended use operator who will perform testing under this protocol.

A subject's participation in this study will consist of a single visit. Following completion of the informed consent process and a review of Inclusion/Exclusion criteria to determine eligibility, each subject will receive a unique study identification number.

Subjects will have nasopharyngeal or nasal or throat swabs collected. Capillary blood may be collected alongside nasal swabs. Saliva samples may also be collected. Specimens will be obtained from each subject enrolled using standard collection methods.

The LumiraDx SARS-CoV-2 Ag Test will be performed at POC sites by intended use operators (e.g. nurses, physician assistants, medical assistants, etc.). Each site will have a minimum of one (1) untrained intended use operator who will perform testing under this protocol.

The LumiraDx SARS-CoV-2 Ag Test will be performed at the site on the same day as the date of collection using one swab for each subject enrolled. A central laboratory will perform reference testing.

Positive Percent Agreement (PPA) and Negative Percent Agreement (NPA) will be estimated for the LumiraDx SARS-CoV-2 Ag Test results as compared with the reference Test.

A minimum of thirty (30) positive SARS-CoV-2 are required, but it is likely because of the prevalence of SARS-CoV-2 in the population, that a greater number of negatives will be obtained during the prospective collection of positive samples; therefore, approximately four-hundred (400) subjects will be enrolled. A minimum of thirty (30) negative samples are required.

Inclusion Criteria:

• 1. The subject may be of any age and either sex.
• 2. Preliminary assessment of the subject by the Investigator/designee should be suggestive of COVID-19 at the time of the study visit. The subject must present as symptomatic, meaning they have exhibited one or more of the following signs and symptoms for eligibility: fever, cough, shortness of breath, difficulty breathing, muscle pain, headache, sore throat, chills, repeated shaking with chills, new loss of taste or smell. The onset of these symptoms will be recorded.

or The subject must have a documented SARS-CoV-2 PCR test in the past 48 hours.

• 3. Written informed consent must be obtained prior to study enrollment.

  1. A subject who is eighteen (18) years or older must be willing to give written informed consent and must agree to comply with study procedures.
  2. The Legal Guardian or Legal Authorized Representative of a subject who is under the age of eighteen (18) must give written informed consent and agree to comply with study procedures. Active written assent should be obtained from children of appropriate intellectual age (as defined by the IRB).

Exclusion Criteria:

• 1. The subject underwent a nasal wash/aspirate as part of standard of care testing during this study visit.
• 2. The subject is currently receiving or has received within the past thirty (30) days of the study visit an experimental biologic, drug, or device including either treatment or therapy.
• 3. The subject has previously participated in this research study

Approximately six (6) geographically diverse POC (Point of Care) locations (e.g. physician office laboratories, urgent cares, emergency departments, outpatient clinics including drive through testing sites or research centers) in the U.S. will participate in the study. Males and females of any age may be enrolled, and should be represented in proportions representative of the population.
