ELISA IgG test for SARS-CoV2

The SARS-CoV-2 IgG ELISA kit is an in vitro diagnostic test for the qualitative detection of IgG antibodies to SARS-CoV-2 in human serum.

The kit is intended for use as an aid in identifying individuals with an adaptive immune response to SARS- CoV-2, indicating recent or prior infection.

At this time, it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity.

The SARS-CoV-2 IgG ELISA KIT should not be used to diagnose acute SARS‑CoV‑2 infection.

Results are for the detection of IgG SARS-CoV-2 antibodies. IgG antibodies to SARS-CoV-2 are generally detectable in blood several days after initial infection, although the duration of time antibodies are present post-infection is not well characterized.

Individuals may have detectable virus present for several weeks following seroconversion.

The sensitivity of SARSARS-CoV-2 IgG ELISA early after infection is unknown. Negative results do not preclude acute SARS-CoV-2 infection. If acute infection is suspected, direct testing for SARS-CoV-2 is necessary.

False positive results for SARS-CoV-2 IgG ELISA may occur due to cross-reactivity from pre-existing antibodies or other possible causes.
