The PocRoc SARS-CoV-2 Antigen Rapid Test Kit (TRFIA) is an immunofluorescent sandwich assay. It can detect the virus with very high sensitivity and specificity. When the sample is applied to the sample wells, SARS-CoV N protein and labeled antibody complexes are formed and travel up the strip. The labeled microsphere fluorescent probe reagent is used to form a visible red line with a matched UV flashlight. The presence of SARS-CoV-2 will be indicated by a visible red test line (T) in the result window. The membrane is pre-coated with Chicken IgY on the control (C) line. Control (C) line appears in each result window when the sample has flowed through the strip.
