Hepatitis B Surface Antibody, Quantitative (anti-HBs)
Detects antibody produced in response to HBV surface antigen. It is used to detect previous exposure to HBV; it can also develop from successful vaccination so it is used to determine the need for vaccination (if anti-HBs is absent) or to determine if a person has recovered from an infection and is immune (cannot get the infection again).
This assay is used to determine immune status for Hepatitis B as ≥10 mIU/mL as per CDC Guidelines.
