Laboratory Testing for Hepatitis B

Anti-HBs - Qualitative vs Quantitative

Slide 9

June 2008

I want to mention briefly about the indications and use of qualitative versus quantitative Hepatitis B surface antibody. The qualitative Hepatitis B surface antigen is mainly indicated to stage Hepatitis B infection, to determine whether it’s past infection versus chronic. As in the case of chronic Hepatitis B, the surface antibody would be absent.

It is also useful to determine immunity status to Hepatitis B infection because when the result is positive, it is indicated that it’s greater than or equal to 10 miU/mL which is the World Health Organization standard for conferring protection from Hepatitis B infection.
