WS-1696WANTAI SARS-CoV-2 IGRA is an enzyme-linked immunosorbent assay for quantitative detection of Interferon Gamma that responds to in-vitro stimulation by spike protein of SARS-CoV-2 in human whole blood.
SARS-CoV-2 IGRA is intended for use as an aid in the diagnosis of specific T cellular immune response of SARS-CoV-2 spike protein after vaccination or infection.
Specific T lymphocytes of SARS-CoV-2 after vaccination is stimulated and proliferated by SARS-CoV-2 specific antigen (spike protein), then release Interferon Gamma.
SARS-CoV-2 IGRA kit uses the principle of IGRA
combined with enzyme linked immunosorbent assay (ELISA) to measure specific antigen mediated immune response strength.
