Other screening tests that can be done include anti-HBc antibody to hepatitis B core antigen and IgM anti-HBc IgM subclass to hepatitis B core antigen. Anti-HBs or HBsAb Hepatitis B surface antibody - A positive or reactive anti-HBs or HBsAb test result indicates that a person is protected against the hepatitis B virus.

The hepatitis B surface antibody test HBsAb looks for antibodies that your immune system makes in response to the surface protein of the hepatitis B virus. Lab report for a Positive Hepatitis B Surface Antibody Titer titer. The hepatitis B surface antibody is also referred to as anti-HBs and should not be confused with HBsAg which stands for hepatitis B surface antigen.

Hepatitis B surface antigen HBsAg. Hepatitis B Surface Antibody Immunity Quantitative - This assay is used to determine immune status for Hepatitis B as 10 mIUmL as per CDC Guidelines. The test is performed by drawing a blood sample and analyzing it in a lab.

Anti-HBs appears after convalescence from acute infection and lasts for many years. Since there are different serologic subtypes of hepatitis B virus it is possible and has been reported for a patient to have antibody to one surface antigen type and to be acutely infected with a virus of a different subtype. The hepatitis B surface antibody anti-HBs is the antibody that is produced in response to hepatitis B surface antigen HbsAg a protein present on the surface of the hepatitis B virus.

The hepatitis B titer sometimes known as an HBsAb test and an anti-HBs titer measures the hepatitis B surface antibody level in the blood to check for immunity to Hepatitis B. Following a vaccination regimen anti-HBs can be measured to determine if protective immunity has been achieved. A positive anti-HBs titer combined with a negative hepatitis B surface antigen HBsAg titer at 12 to 15 months of age indicates effective treatment for infants born to HBsAg-positive mothers and treated with hepatitis B immunoglobulin HBIG and HBV vaccination.

It can be detected in high levels in serum during acute or chronic hepatitis B virus infection. A hepatitis B titer measures the dilution of the antibodies for the hepatitis B virus against the amount of antibody needed to neutralize the antigen. It is not a marker of vaccine-induced immunity.

Three different serologic tests are needed hepatitis B surface antigen HBsAg hepatitis B surface antibody anti-HBs and total hepatitis B core antibody anti-HBc to determine whether a patient has acute or chronic HBV infection and is in need of post-test counseling and linkage to care 11.

Up to three additional vaccinations should be given if the anti-HBs titer remains below 100 IUL. If the anti-HBs remains lower than 10 IUL there is no protection against hepatitis B. A protein on the surface of hepatitis B virus.

The hepatitis B titer test can help determine if a patients blood contains enough antibodies to ward off hepatitis B. If you wish to know whether the vaccine is effective you can have your anti-HBs titers checked following the last shot of the hepatitis B vaccine series.

It is not a routine blood test so it is not likely that you have done it in the past unless needed for another academic health related program or job. Anti-HBc totalAntibody to hepatitis B core antigenis a nonspecific marker of acute chronic or resolved HBV infection.

Vaccinations for Hep A and B can provide protective antibodies which immunize a person from catching the virus. It may be used in prevaccination testing to determine previous exposure to HBV infection. Someone with a titer between 10 and 100 IUL is protected if the titer was measured twice but it is still unknown how long protection will last.
