Hepatitis B (HBV) Blood Test Panel
A Hepatitis B (HBV) Blood Test Panel includes a Hepatitis B Core Antibody Total (Test #006718), Hepatitis B Surface Antigen (Test #006510), Hepatitis B Surface Antibody (Test #006395).
Hepatitis B Blood Test Panel includes:
Anti-Hepatitis B Core Antigen is an antibody to the hepatitis B core antigen. The core antigen is found on virus particles but will disappear early in the course of infection. This antibody is produced during and after an acute HBV infection and is normally found in chronic HBV carriers and those who have cleared the virus, and usually persists for life. Anti-HBc testing is either specific for the IgM antibody, anti-HBc, IgM, which will indicate acute infection, or measures total antibody, anti-HBC, which will indicate past infection, either acute or chronic.
The Hepatitis B Surface Antibody (anti-HBs) is the most common test. Its presence will indicate previous exposure to HBV, but the virus is no longer present and the person cannot pass virus on to others. The antibody will also protect the body from future HBV infection. In addition to exposure to HBV, these antibodies can also be acquired from successful vaccination. This test is peformed to determine the need for vaccination (if anti-HBs is absent), or following the completion of vaccination against the disease, or following an active infection.
Hepatitis B Surface Antigen (HBsAg) is a protein antigen produced by HBV. This antigen is the earliest indicator of acute hepatitis B and often identifies infected people before symptoms appear. HBsAg will disappear from the blood during the recovery period. In some people (those infected as children or those with a weak immune system, such as those with AIDS), chronic infection with HBV may occur and HBsAg will remain positive.
