The Alfa Instant-view® PLUS COVID-19 rapid antigen test is a rapid chromatographic immunoassay intended for rapid qualitative detection of nucleocapsid antigens from SARS-CoV-2 virus in the human nasal swab, from individuals who are suspected of COVID-19 by their healthcare provider within the first five days of the onset of symptoms.
Results are for the identification of COVID-19 nucleocapsid antigen. Antigen is generally detectable in upper respiratory samples or lower respiratory samples during the acute phase of infection.
Positive results indicate the presence of viral antigens, but the clinical correlation with patient history and other diagnostic information is necessary to determine infection status.

Reporting results: Alfa Instant-view® PLUS COVID-19 rapid antigen test for SARS-CoV-2
Positive for the presence of COVID-19 antigen. Positive results indicate the presence of viral antigens, but the clinical correlation with patient history and other diagnostic information is necessary to determine infection status. Positive results do not rule out a bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of the disease. Laboratories within the United States and its territories are required to report all positive results to the appropriate public health authorities.
Negative results are presumptive. Negative test results do not preclude infection and should not be used as the sole basis for treatment or other patient management decisions, including infection control decisions, particularly in the presence of clinical signs and symptoms consistent with COVID-19, or in those who have been in contact with the virus. It is recommended that these results be confirmed by a molecular testing method, if necessary, for patient management Control.
Do not report results. Repeat the test.
