Hepatitis B Surface Antibody Immunity, Quantitative details
What Hepatitis B Surface Antibody Immunity, Quantitative shows
Hepatitis B surface antibody (anti-HBs) is the antibody your immune system makes against the outer surface protein of the hepatitis B virus. It develops after successful vaccination or after recovering from a past infection. This quantitative test measures how much anti-HBs is in your blood, which is useful for confirming a response to vaccination, for example in healthcare workers. A result above the protective level indicates immunity, while a low or undetectable result can mean you did not respond to vaccination, your antibody levels have waned, or you were never exposed. It does not tell vaccination from past infection on its own, so it is interpreted alongside other hepatitis B tests.
