COVID-19 antibody total ELISA test is a laboratory test that is used to detect the presence of antibodies against the SARS-CoV-2 virus that causes COVID-19 in a person's blood. The total antibody test detects the presence of both IgG and IgM antibodies, which are produced by the body's immune system in response to an infection.
The COVID-19 antibody total ELISA test can help to determine whether a person has been infected with the SARS-CoV-2 virus in the past and has developed immunity to the virus. However, it is important to note that a positive result does not necessarily mean that a person is immune to COVID-19, as the level of antibodies can vary between individuals and over time. Additionally, a negative result does not rule out a previous COVID-19 infection.
