Hepatitis B Surface Ab, Qualitative
5-7 Business Days
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).
The detection of anti-HBs is indicative of a prior immunologic exposure to the antigen or vaccine. To determine immune status as =10 mIU/mL as per CDC guidelines, please order Hepatitis B Surface Antibody, Quantitative.
