" Know Your Immunity Level After Vaccination with COVID-19 Spike Protein IgG Antibody Test "

COVID-19 Spike Protein IgG Quantitative Antibody (CMIA) Test - After Vaccination

This test provides quantitative result for the presence of antibodies to receptor binding domain (RBD) on SARS-coV-2 spike protein. Both vaccine and active infection can stimulate antibodies against this domain.

Method: Chemiluminescent Microparticle Immunoassay.

The potential risks and benefits of the test?

  • Results and other information can help your health care provider make informed recommendations about your care
  • Test results may help limit the spread of COVID-19 to your family and others in your community

What does it mean if I have a positive test result?

If you have a positive test result (antibodies are detected), you may have been infected with the virus that causes COVID-19 at some point in the past, or you have made antibodies as a response to vaccination with one of the current SARS-CoV-2 vaccines. There is still a chance that the antibodies indicate past infection due to other coronaviruses. These other coronaviruses cause the common cold. There is also a small chance that a positive result is incorrect (false positive).

The presence of IgG suggests that the infection or vaccination happened weeks to months in the past. It also suggests that you may no longer be infectious. IgG indicates that you may have some immunity to the virus, though you may not. How much it might protect you from getting sick with COVID-19 in the future is unknown.

Your health care provider will work with you to determine how best to care for you based on the test results along with other factors of your medical history, including any previous symptoms, possible exposure to COVID-19 and the location of places you have recently traveled.

What does it mean if I have a negative test result?

A negative test result means that the antibodies to the virus that causes COVID-19 or to the vaccine were not found in your sample. Some health conditions might make it difficult for your body to produce antibodies to an infection or vaccination. However, it is possible for this test to give a negative result that is incorrect (false negative) in some people.

A negative result may occur if you are tested early in your illness or shortly after vaccination and your body hasn’t had time to produce antibodies. This means that you could possibly still have COVID-19 even though the test is negative or that it too early after vaccination to detect antibodies. If this is the case, your health care provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures and geographical location of places you have recently traveled) in deciding how to care for you.

It is important that you work with your health care provider to help you understand the next steps you should take.
