Hepatitis A antibody is produced in response to an infection with the Hepatitis
A virus or to the Hepatitis A vaccine. The test detects the presence of this
antibody. |
|
|
|
|
|
|
|
Antibodies are produced by the body to protect it self from antigens (foreign
proteins). IgM (immunoglobulin M) is the first antibody produced by the body
when it is exposed to a virus and is used for early detection of infection. IgM
antibodies to HAV are used in a patient with evidence of acute Hepatitis, such
as jaundice, dark urine, pale colored stools, fever, and loss of appetite. IgG
(immunoglobulin G) antibodies develop later and remain present for many years,
protecting the person against further infection by the same virus. A total
antibody test (which detects both IgM and IgG antibodies) detects both current
and previous infection with HAV and also will be positive after receiving the
Hepatitis A vaccine.
|
|
|
|
|
|
|
|
Testing for the presence of IgM antibodies to Hepatitis A is done if you have
the symptoms and/or are likely to have been exposed to the virus. If you have
being considered for the HAV vaccine, a total antibody test may be ordered
before you are given the vaccine to see if you need it (if the antibodies are
already present, the vaccine won’t help you). Once you have completed the two
doses of the vaccine, the total HAV antibody test can also be used to see if you
have responded to the vaccine. |

Hepatitis B antibodies are produced in response to exposure to the Hepatitis B
virus (HBV). The tests detect the presence of these antibodies or parts
(antigens) of the virus itself. There are several tests used to detect the
presence of Hepatitis B antibodies. Antibodies are produced by the body to offer
protection from antigens (foreign proteins). There are also several tests that
detect the presence of viral antigens. |
|
|
|
|
|
|
|
|
|
|
The Hepatitis B surface antibody (Anti-HBs) is the most common test. Its
presence indicates previous exposure to HBV, but the virus is no longer present
and the person cannot pass on the virus to others. The antibody also protects
the body from future HBV infection. In addition to exposure to HBV, the
antibodies can also be acquired from successful vaccination. This test is done
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 frequently identifies
infected people before symptoms appear. HBsAg disappears from the blood during
the recovery period. In some people (particularly those infected as children or
those with a weak immune system, such as those with AIDS), chronic infection
with HBV may occur and HBsAg remains positive. |
|
|
|
|
|
|
|
Sometimes, HBV goes into “hiding” in the liver and other cells and does not
produce new viruses that can infect others, or produces them in such low amounts
that they cannot be found in the blood. People who have this form are said to be
carriers. In other cases, the body continues to make viruses that can further
infect the liver and can be spread to other people. In both these cases, HBsAg
will be positive. |

Hepatitis B e-antigen (HBeAg) is a viral protein associated with HBV infections. Unlike the surface antigen, the e-antigen is found in the blood only when there are viruses also present. When the virus goes into “hiding,” the e-antigen will no longer be present in the blood. HBeAg is often used as a marker of ability to spread the virus to other people (infectivity). Measurement of e-antigen may also be used to monitor the effectiveness of HBV treatment; successful treatment will usually eliminate HBeAg from the blood and lead to development of antibodies against e-antigen (Anti-HBe). There are some types (strains) of HBV that do not make e-antigen; these are especially common in the Middle East and Asia. In areas where these strains of HBV are common, testing for HBeAg is not very useful. |
|
|
|
|
|
|
|
Anti-HBe is an antibody produced in response to the Hepatitis B e antigen. In
those who have recovered from acute Hepatitis B infection, Anti-HBe will be
present along with Anti-HBc and Anti-HBs. In those with chronic Hepatitis B,
usually Anti-HBe becomes positive when the virus goes into hiding or is
eliminated from the body. In strains that do not make Hbe antigen, Anti-HBe is
also positive. |

Anti-Hepatitis B core antigen (Anti-HBc) is an antibody to the Hepatitis B core
antigen. The core antigen is found on virus particles but disappears early in
the course of infection. This antibody is produced during and after an acute HBV
infection and is usually found in chronic HBV carriers as well as 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 indicates acute infection,
or measures total antibody, Anti-HBc, which indicates past infection, either
acute or chronic. |
|
|
|
|
|
|
|
HBV DNA is a more sensitive test than HBeAg for detecting viruses in the blood
stream. It is usually used in conjunction with – rather than instead of – the
regular serologic tests. It may be used to monitor antiviral therapy in patients
with chronic HBV infections. |
