MDx COVID-19 Ag Home Test is an in vitro diagnostic medical device used to aid in the diagnosis of SARS-CoV-2 infection by qualifying SARS-CoV-2 antigen(nucleocapsid protein) with immunochromatographic assay(ICA) from the self collected nasal swab by the individuals suspected of respiratory infection.
Even if the lines are faint, the lines (C line, T line) are considered present.
A colored band should always be visualized at C line regardless of the results at T line. If C line is not visualized, it is a no test. The retest is recommended using new Test Device.
