Hepatitis B Surface Antibody, Qualitative(anti-HBs)
Detects only the IgM antibody to the hepatitis B core antigen. Used to detect acute infections; sometimes present in chronic infections as well as 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.
