# SARS-CoV-2 Semi-Quantitative IgG Antibody, Spike

> This test measures the level of IgG antibodies in your blood that target the spike protein of the virus responsible for COVID-19. Because these antibodies develop over time, the results help determine if your immune system has previously responded to the virus through past infection or vaccination. However, this test cannot diagnose a current, active COVID-19 infection or guarantee that you have immunity against future illness.
