The COVID-19 neutralizing antibody test is a laboratory test that is used to measure the level of antibodies in a person's blood that can neutralize the SARS-CoV-2 virus that causes COVID-19. Neutralizing antibodies are a type of antibody that can block the virus from infecting cells.
The COVID-19 neutralizing antibody test is considered to be a more specific and sensitive test for measuring immunity to the SARS-CoV-2 virus compared to other antibody tests, as it specifically measures the ability of antibodies to neutralize the virus. However, it is important to note that a positive result does not necessarily mean that a person is completely protected against COVID-19, as there may be other factors involved in immunity to the virus such as T cell responses and other immune mechanisms.
