This a Quest Diagnostics Test and the specimen will be collected at a Quest Diagnostics location.
SARS-CoV-2 Serology (COVID-19) Antibody (IgG), Immunoassay TEST - Detection IgG antibodies may indicate exposure to SARS-CoV-2 (COVID-19).
Typically it takes at least 10 days after symptom onset for IgG to reach detectable levels.
Kindly note that an IgG positive result may suggest an immune response to a primary infection with SARS-CoV-2, but the relationship between IgG positivity and immunity to SARS-CoV-2 has not yet been firmly established.
Antibody blood tests, also called antibody tests, check your blood by looking for antibodies, which show if you had a previous infection with the virus. Depending on when someone was infected and the timing of the test, the test may not find antibodies in someone with a current COVID-19 infection. Antibodies are proteins that help fight off infections. Antibody tests should not be used as the only way to diagnose someone as being currently sick with COVID-19.
