SARS-CoV-2 Antigen Rapid Test

COVID-19 Ag is a lateral flow immunochromatographic
assay that adopted dual color system. The test contains colloid gold
conjugate pad and a membrane strip pre-coated with antibodies specific
to SARS-CoV-2 antigen on the test lines (T). If SARS-CoV-2 antigen is
present in the specimen, a visible black band appears on the test lines (T)
as antibody-antigen-antibody gold conjugate complex forms. The control
line (C) is used for procedural control and should always appear if the
test is performed correctly.
