Hepatitis B Package
Understanding Hepatitis B Package
What is Hepatitis B Package?
Hepatitis B Package involves blood tests used to detect current or past infection by hepatitis B. It includes tests for various antigens and antibodies to give a clear picture of Hepatitis B virus (HBV) in the body which helps doctors formulate an appropriate treatment plan. This package includes 6 components.
HBsAg (Australia antigen) is the first serologic marker to appear in serum after Hepatitis B Virus (HBV) infection. Hbsag test is done for diagnosis of acute, recent, and chronic cases of hepatitis. Test is positive after 4 weeks of infection but may be detected any time after the first week. Test plays an important role in management of HBV disease.
Hepatitis B (Core) IgM Antibody indicates a recent or acute infection.
Hepatitis B e (Envelope) Antibody is a small polypeptide that exists in a free form in the serum of individuals during the early phase of hepatitis B infection, soon after hepatitis B surface antigen (HBsAg) becomes detectable. In your body, the Hepatitis B e-Antigen (HbeAg) serves as a marker for active hepatitis B virus infection. It indicates the presence of the virus actively replicating in your liver. Monitoring HBeAg levels is crucial in managing hepatitis B.
Hepatitis B s (Surface) Antibody is done to determine a very recentor acute HBV infection.
The Anti HBsAg test is used to determine past exposure & status of adequate immunity in vaccinated individuals
Hepatitis B (Core) Total Antibody measures the levels of total antibodies to the core antigen of Hepatitis B Virus (HBV) in the blood. These antibodies provide information about a person's immune response to HBV and help diagnose and monitor HBV infection.

Hepatitis B Surface Antigen (HBsAg)
The Hepatitis B Surface Antigen (HBsAg) test detects the presence of a specific protein on the surface of the Hepatitis B virus (HBV) in the bloodstream. This protein, HBsAg, serves as a crucial marker for identifying HBV infection. This is a screening test and the diagnosis of any reactive HBsAg result relies on additional supplemental tests like anti-HBs antibody and total anti-HBc antibodies. Confirmation can be done using nucleic acid tests like HBV DNA by PCR. The Hepatitis B Surface Antigen (HBsAg) test is essential for identifying individuals who require medical intervention, such as antiviral therapy, and for implementing measures to prevent the spread of Hepatitis B virus to others.

Hepatitis B s (Surface) Antibody
The Hepatitis B s (Surface) Antibody test measures the presence of antibodies produced by the immune system against hepatitis B virus (HBV) or the hepatitis B vaccine (immunity) in vaccinated individuals. There are two types of antibodies produced in response to the hepatitis B virus: Immunoglobulin M (IgM) and Immunoglobulin G (IgG). IgM antibodies mount the first attack against HBV but eventually fades away. IgG antibodies provide long-lasting immune protection against HBV. The immunity can last for many years, but it gradually decreases over time.
A positive test result indicates immunity to hepatitis B, either from past infection and subsequent recovery or from vaccination. The Hepatitis B s (Surface) Antibody test is important to determine whether you have protective immunity against HBV and if you are at risk of contracting the virus in the future. It can also help guide decisions on whether you need the hepatitis B vaccine or a booster shot to maintain immunity.
