I recently went to donate blood and a few weeks later received the results below
Hepatitis B Core Antibody - Reactive
Hepatitis B Virus Nucleic Acid Testing - Non-reactive
Hepatitis B Surface Antigen - Non-reactive
Thanks @Dadz1990 Don't I need to take Hepatitis B Surface Antibody test to confirm immunity? When I last tested in 2018, Hepatitis B Surface Antigen was also negative. The results then (2018) don't include Hepatitis B Core Antibody though.
