On Oct. 19, 2020, LabCorp announced a test that provided a quantitative measurement of an individualﾒs SARS-CoV-2 IgG antibodies. LabCorpﾒs Cov2Quantﾙ IgG test, which is available only for use in clinical trials and research, was developed to specifically detect and quantify antibodies to SARS-CoV-2, the virus that causes COVID-19.

The level of antibodies is an important indicator of the strength of a personﾒs immune response, which can help determine the effectiveness of vaccines and therapies. Other COVID-19 antibody tests available in the market are qualitative and detect the presence of antibodies, but do not provide information on the individualﾒs antibody levels.
