  2. HBsAg - Wikipedia

    en.wikipedia.org/wiki/HBsAg

    Patients who developed antibodies against HBsAg (anti-HBsAg seroconversion) are usually considered non-infectious. HBsAg detection by immunoassay is used in blood screening, to establish a diagnosis of hepatitis B infection in the clinical setting (in combination with other disease markers) and to monitor antiviral treatment.

  3. Hepatitis B - Wikipedia

    en.wikipedia.org/wiki/Hepatitis_B

    If the host is able to clear the infection, eventually the HBsAg will become undetectable and will be followed by IgG antibodies to the hepatitis B surface antigen and core antigen (anti-HBs and anti HBc IgG). [39] The time between the removal of the HBsAg and the appearance of anti-HBs is called the window period. A person negative for HBsAg ...

  4. Seroconversion - Wikipedia

    en.wikipedia.org/wiki/Seroconversion

    The presence of surface antibody (anti-HBs) indicates an individual with immunity to hepatitis B, whether due to previously resolved infection or due to hepatitis B vaccination. [65] For example, an individual who has never had any exposure to HBV, either by vaccine or by infection, would test negative for the entire serology panel.

  5. Hepatitis B virus - Wikipedia

    en.wikipedia.org/wiki/Hepatitis_B_virus

    HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]

  6. HBeAg - Wikipedia

    en.wikipedia.org/wiki/HBeAg

    HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).

  7. Hepatitis - Wikipedia

    en.wikipedia.org/wiki/Hepatitis

    Viral hepatitis is primarily diagnosed through blood tests for levels of viral antigens (such as the hepatitis B surface or core antigen), anti-viral antibodies (such as the anti-hepatitis B surface antibody or anti-hepatitis A antibody), or viral DNA/RNA. [17] [32] In early infection (i.e. within 1 week), IgM antibodies are found in the blood ...

  8. Laboratory diagnosis of viral infections - Wikipedia

    en.wikipedia.org/wiki/Laboratory_diagnosis_of...

    To do this, antibodies that are specific to different types of viruses are mixed with the tissue sample. After the tissue is exposed to a specific wavelength of light or a chemical that allows the antibody to be visualized. [citation needed] These tests require specialized antibodies that are produced and purchased from commercial companies.

  9. HBcAg - Wikipedia

    en.wikipedia.org/wiki/HBcAg

    HBcAg, also called core protein (Cp), is a 21 kDa protein of 183–185 amino acids, depending on the genotype, and is the result of the second start codon in the open reading frame. [6] Once a threshold of HBcAg proteins are translated in the cytoplasm, the viral capsid will spontaneously into a T=3 or T=4 icosahedral capsid . [ 7 ]
