Antibodies and Antibody Tests: The Basics
Q: What are antibodies? A: Antibodies are proteins made by your body's immune system to help fight off infections, including those caused by viruses. Some antibodies in your body may protect you from getting those infections. Your immune system can also safely learn to make antibodies through vaccination. If antibodies give you this protection and how long this protection lasts can be different for each disease and each person. Antibodies are just one part of your immune response. Q: Are antibody tests used to diagnose COVID-19? A: No. An antibody test cannot be used to diagnose current COVID-19 because an antibody test does not detect SARS-CoV-2. Only COVID-19 diagnostic testscan be used to diagnose current COVID-19. A positive antibody test result can be used to help identify people who may have had a prior SARS-CoV-2 infection or prior COVID-19. An antibody test does not show if you have a current SARS-CoV-2 infection or COVID-19 because the antibodies are part of the body's immune response to infection, and antib
Antibody Tests: Not For Use to Check Immunity
Q: Will a positive result on a SARS-CoV-2 antibody test mean I have immunity and I will not get COVID-19? A: No. At this time, SARS-CoV-2 antibody tests do not tell you if you have immunity that will prevent you from getting COVID-19. A positive SARS-CoV-2 antibody test does not necessarily mean you are immune or have immunity that will prevent COVID-19. More research is needed to understand what SARS-CoV-2 antibody test results can tell us. And, SARS-CoV-2 antibodies detected in your blood reflect only one part of your immune system, which also includes T-cells and other components that are part
Antibody Tests: Results and Terms
Q: What does a positive SARS-CoV-2 antibody test result mean? A: A positive antibody test result could mean you previously had a SARS-CoV-2 infection or COVID-19. A positive antibody test could also mean the test is detecting antibodies in your blood in response to your COVID-19 vaccine. Not all SARS-CoV-2 antibody tests will detect antibodies in response to a COVID-19 vaccine. Q: What does a negative SARS-CoV-2 antibody test result mean? A: A negative result on a SARS-CoV-2 antibody test means antibodies to the virus were not detected in your blood. It is unknown if all people who have a SARS-CoV-2 infection will develop antibodies in their bodies in an amount that can be detected by a SARS-CoV-2 antibody test. Also, even if people do develop antibodies, the antibody levels may decrease over time to levels that can't be detected by a SARS-CoV-2 antibody test. It is also important to note that different antibody tests may dete
