SARS-CoV-2 Serology (COVID-19) Antibodies (IgG, IgM), Immunoassay (Covid 19 IgG Antibody)

“Detection of IgG and IgM antibodies may indicate exposure to SARS-CoV-2 (COVID-19). IgM antibodies to SARS-CoV-2 are generally detectable in blood several days after initial infection, with IgG antibodies typically reaching detectable levels simultaneously or 1-2 days later. Separate results will be provided for IgM and IgG. A positive antibody result may suggest an immune response to a primary infection with SARS-CoV-2, but the relationship between positivity and immunity to SARS-CoV-2 has not yet been firmly established. Antibody tests have not been shown to definitively diagnose or exclude SARS-CoV-2 infection. Diagnosis of COVID-19 is made by detection of SARS-CoV-2 RNA by molecular testing methods, consistent with a patient’s clinical findings. “
