Understanding COVID-19 antibodies:
Test your knowledge on COVID-19 antibody testing
Since the beginning of the COVID-19 pandemic, researchers have been racing to build scientific knowledge about the disease. After all, answers are essential to helping us stay one step ahead of the virus. Take this quiz to see if you have the right answers on COVID-19 antibody testing!
Fact or Fiction?
SARS-CoV-2 is the virus
that causes COVID-19 disease.
True. COVID-19, which stands for
Coronavirus Disease 2019, is the name of the disease, while the scientific name of the virus is SARS-CoV-2, which stands for severe acute respiratory syndrome coronavirus 2.
Oops! The correct answer is:
Antibody tests, like the Roche Elecsys®
Anti-SARS-CoV-2 S antibody test, can be used to diagnose COVID-19.
False. COVID-19 can be diagnosed using either a polymerase chain reaction (PCR) test or an antigen test, both of which detect components that make up the virus in a respiratory sample.
High levels of antibodies indicate that a person is completely immune from COVID-19.
False. Higher levels of antibodies provide more protection, but scientists still don't know what level of antibodies is required to say that a person is immune to the disease.
The Roche Elecsys® Anti-SARS-CoV-2 S test measures antibodies produced after a person has had COVID-19, as well as after a person has been vaccinated against COVID-19.
True. Both an infection with SARS-CoV-2 and the vaccine against COVID-19 stimulate the body to produce an immune response, which includes antibody production. The Roche Elecsys® Anti-SARS-CoV-2 S test detects these antibodies.
Antibody tests, like the Roche Elecsys® Anti-SARS-CoV-2 S,
can help scientists determine the level of antibodies necessary for immunity.
True. By looking at antibody levels in patients who become infected after vaccination (or re-infected after an infection), scientists can help determine the level of antibodies needed for protection against COVID-19.
People who are immunocompromised will probably have a good antibody response to a natural
COVID-19 infection, but not necessarily to the vaccine.
False. People with lowered immune systems may not produce an adequate antibody response after a natural infection or following vaccination.
All antibody tests can indicate the level (or quantity)
of antibodies that are present.
False. Some antibody tests tell whether a person has antibodies or not (qualitative result), but do not indicate the exact level of antibodies that are present (quantitative result). The Roche Elecsys® Anti-SARS-CoV-2 S test can provide both qualitative and quantitative results.
The Roche Elecsys® Anti-SARS-CoV-2 S test uses a
saliva sample to perform the test.
False. The test is performed on a blood sample via a usual blood draw.
