A positive antibody test does not mean you are immune to SARS-CoV-2 infection; it is unclear if possessing antibodies to SARS-CoV-2 will keep you from becoming sick again. It also doesn't say whether or not you can spread SARS-CoV-2 to others.

What does an antibody-negative test mean?
Antigen tests and antigen tests are two different types of covid19 tests . Antibodies to SARS-CoV-2 were not discovered in your sample, resulting in a negative result on a SARS-CoV-2 antibody test. It could indicate that: • You have never been infected with COVID-19 before.
- You previously had COVID19 but did not develop or have not developed detectable antibodies. It's unclear if all infected people will have detectable antibody responses.
- A false negative is when the result is incorrect. This happens when the test fails to detect antibodies, despite the fact that you may have SARS-CoV-2-specific antibodies.
There are various reasons why negative antibody test results do not guarantee that you are not infected with SARS-CoV-2 or that you have never been infected with it.
If you are tested immediately after being infected with SARS-CoV-2, for example, the test may come out negative since the body needs time to build an antibody response. It's also unclear whether antibody levels drop to undetectable levels over time.
Overview antibody testing:
COVID19 antibody testing, also known as serology testing, is a blood test used to determine if you have ever been infected with SARS-CoV-2, the virus that causes coronavirus disease (COVID19). Antibody tests can't tell you if you're infected with the COVID19 virus right now.
