Description
SARS-CoV-2 IgG antibody level (ABOTT, CMIA method) – quantitative test:
A highly sensitive and specific assay that examines the level of IgG antibody to the SARS-COV2 virus in quantitative form. Other tests show only whether or not the antibody is detectable. This test gives the actual level of the antibody (IgG).
IgG is the ‘long-term’ antibody that is produced after infection. Sars-Cov2 IgG level will help to determine if you have had an asymptomatic infection, or in case of known prior COVID 19 infection, if your body produces the virus-specific antibodies.
Because IgG antibody only begins to be produced in the body 7 to 10 days after infection, it does not make sense to perform this test in the acute phase of coronavirus infection. It can be tested at the earliest after 2-3 weeks from the onset of infection. If the antibody level is still low at that time, it should be done again 2-3 weeks later.
The level of SARS-Cov19 may correlate with immunity against the virus. However, this issue is still under investigation.
Test results are available in two to four work days.
