Understanding if a patient has been recently or previously infected with SARS-CoV-2 and how long antibodies stay in the body is an important next step in the fight against the virus. Serology tests can provide this broader picture. Abbott is partnering with laboratories around the world in the COVID-19 crisis by quickly bringing assays for the specific detection of SARS-CoV-2 antibodies. These tests are produced in the volumes required to support the urgent needs of laboratories in their mission to support ongoing patient care.

The AdviseDx SARS-CoV-2 IgM assay is a chemiluminescent microparticle immunoassay (CMIA) intended for the qualitative detection of IgM antibodies to SARS-CoV-2 in human serum, serum separator tube and plasma (dipotassium EDTA, tripotassium EDTA, lithium heparin, lithium heparin separator tube, sodium heparin). The AdviseDx SARS-CoV-2 IgM assay 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 AdviseDx SARS-CoV-2 IgM assay should not be used to diagnose acute SARS-CoV-2 infection. 3,4

The SARS-CoV-2 IgG assay is a chemiluminescent microparticle immunoassay (CMIA) intended for the qualitative detection of IgG antibodies to SARS-CoV-2 in human serum, serum separator tube and plasma (ACD, CPD, CPDA-1, dipotassium EDTA, tripotassium EDTA, lithium heparin, lithium heparin separator tube, sodium citrate, sodium heparin). The SARS-CoV-2 IgG assay 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 assay should not be used to diagnose acute SARS-CoV-2 infection.7,8

The positive agreement between the ARCHITECT i2000SR and the Alinity i was 100% and the negative agreement was 99.00%.
a Five specimens from 1 immunocompromised patient were excluded from the study. Refer to the LIMITATIONS OF THE PROCEDURE section of the package insert for further information. When the results from these specimens were included, the PPA at ≥ 14 days post-symptom onset was 96.77% (95% CI: 90.86, 99.33).
More than 60,000 samples have been evaluated with Abbott’s SARS-CoV-2 assays in more than 20 publication/evaluations, seeking to provide key insights. Here are a few examples.

|Performance Characteristics of the Abbott Architect SARS-CoV-2 IgG Assay and Seroprevalence in Boise, Idaho||Research from the University of Washington, published in the Journal of Clinical Microbiology, found our SARS-CoV-2 IgG assay had 99.9% specificity and 100% sensitivity for detecting the IgG antibody in people 17 days after symptoms began.|
|Prevalence of SARS-CoV-2 in Spain (ENE-COVID): a nationwide, population-based seroepidemiological study||Study published in The Lancet showed how our SARS-CoV-2 IgG assay was recently involved in one of the largest (if not the largest) seroprevalence studies in Europe and it helped Spanish government determine what has happened and inform national and local public health policies.|
|SARS-CoV-2 seroprevalence and neutralizing activity in donor and patient blood from the San Francisco Bay Area||Researchers from University of California, San Francisco, provided evidence that seropositive results using the Architect SARS CoV-2 anti-nucleocapsid protein IgG (EUA) and anti-spike IgM (prototype) assays are generally predictive of in vitro neutralizing capacity.|
