June 2020—ARUP Laboratories announced that it is making a second COVID-19 IgG antibody test available nationwide.
The test, manufactured by Euroimmun, adds to ARUP’s suite of COVID-19 tests, which includes an antibody test manufactured by Abbott and a molecular diagnostic test to detect active SARS-CoV-2 infection. ARUP also offers cytokine tests and other assays that providers are using to help guide COVID-19 treatment decisions.
The two tests differ in that each detects antibodies to a different SARS-CoV-2 viral antigen. The tests also use different methodologies—the Euroimmun test is an enzyme-linked immunosorbent assay while the Abbott test is a chemiluminescent immunoassay.
Both tests report results as positive or negative for IgG antibodies, but the Euroimmun test adds an index value that can be used to measure the level of antibody response to SARS-CoV-2 and to monitor changes in the antibody response to the virus over time with repeat testing.
