Hepatitis B surface antibodies can help a doctor identify different phases of hepatitis B infection and determine whether a person is immune to the virus or susceptible to infection.

Test results for hepatitis B can seem confusing, but they don't have to be. Let's review what the presence or absence or these antibodies means for you: ...

The researchers identified these antibodies within samples donated by COVID-19 survivors. Collectively, the pair are called CoV2-biRNs, and they deliver a one-two punch that disables the virus ...

A hepatitis B nonreactive test result can mean a person is not immune to the virus. Learn how the test works, how to interpret the results, and the next steps.

The antibodies attach to a part of the virus that doesn't appear to mutate, potentially allowing them to work on multiple COVID-19 variants.
