Covid -19 Ab

The SARS-CoV-2 S-RBD IgG Antibody Rapid Test (Whole Blood/Serum/Plasma)
is a qualitative membrane-based immunoassay intended to detect IgG antibodies
to SARS-CoV-2 spike (S) protein receptor binding domain (RBD) in human
serum, plasma, or whole blood. The test is intended as an aid to assess the
adaptive humoral immune response to the SARS-CoV-2 S protein.
Anti-human IgG antibody is coated in the test line region. During testing, SARSCoV-2 IgG antibodies, if present in the specimen, will react with the SARS-CoV-2
S-RBD-coated particles, which have been pre-coated on the test strip. The
mixture then migrates upward on the membrane by capillary action and reacts
with the anti-human IgG antibody in the test line region. As a result, a colored line
will appear in the test line region, indicating a positive result. If the specimen does
not contain IgG antibodies to SARS-CoV-2 spike (S) protein receptor binding
domain (RBD), no colored line will appear in the test line region, indicating a
negative result. To serve as a procedural control, a colored line will always
appear in the control line region, indicating that a proper volume of specimen has
been added and membrane wicking has occurred.
