Ulta Lab Tests

SARS-CoV-2 IgG Antibody Test

The SARS-CoV-2 IgG Antibody Test detects IgG antibodies that develop as an immune response to a prior COVID-19 infection. A positive result confirms past exposure but does not diagnose active illness or detect immunity from vaccination. Doctors use this blood test to evaluate unexplained symptoms, confirm prior infection, and track antibody persistence, providing useful insight into a patient’s history with coronavirus infection.

SARS-CoV-2 Antibody (IgG), Nucleocapsid, Qualitative

Clinical Significance

SARS-CoV-2 Antibody (IgG), Nucleocapsid, Qualitative - This test is intended as an aid in identifying individuals with antibodies to SARS-CoV-2. A positive result indicates an immune response to a recent or prior infection with SARS-CoV-2. This test would not be expected to detect an immune response to a spike vaccine. It is unknown for how long antibodies persist following infection or if the presence of antibodies confers protective immunity. This assay should not be used to diagnose acute SARS-CoV-2 infection.
