About the Test

Antibodies are proteins that the body produces in response to an infection or vaccine. There are 2 types of COVID-19 antibody tests: a spike protein test and a nucleocapsid test.

This COVID-19 Antibody Test is a spike protein test which can detect antibodies from a prior or recent infection, regardless of whether symptoms were present. Positive results may also occur after a COVID-19 vaccination, but the clinical significance is not yet known. A nucleocapsid test can only detect antibodies from a prior or recent infection.
