- This test looks for hepatitis B surface antigens in your blood. The test is used to find out whether you have a recent or long-standing infection from the hepatitis B virus (HBV). HBV has proteins called antigens on its surface that cause your immune system to make antibodies.

Understanding the Hepatitis B e-Antigen or HBeAg HBeAg stands for hepatitis B e-antigen. This antigen is a protein from the hepatitis B virus that circulates in infected blood when the virus is actively replicating. The presence of HBeAg suggests that the person is infectious and is able to spread the virus to other people.

Hepatitis B virus testing HBeAg (hepatitis B e antigen). A positive test result means you have the hepatitis B virus in the bloodstream. If you are HBV DNA positive but this HBeAg test result is negative, then you still have the hepatitis B virus in your bloodstream. positive test result means you have the hepatitis B virus in the bloodstream and this is called chronic hepatitis B.. You may be right for hepatitis B drug treatments.

What Is the Hepatitis B Surface Antibody (HBsAb) Test? The HBsAb test, or hepatitis B surface antibody test, looks for antibodies that your immune system makes in response to the surface protein of the hepatitis B virus. 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.

HBeAg (Hepatitis B e-antigen) A subset of chronic hepatitis B patients have no detectable HBeAg in serum, but are positive for anti-HBe; these patients may also be positive for serum hepatitis B virus DNA. Additionally HBe antigen/antibody seroconversion is used as an indicator of virological response when treating patients with chronic hepatitis B.

- Hepatitis B virus (HBV) tests may be used for a variety of reasons. Some of the tests detect antibodies produced in response to HBV infection; some detect antigens produced by the virus, and others detect viral DNA.

Hep B Titer- (Hep B Surface, antibody) Quantitative This assay is used to determine immune status for Hepatitis B. Hepatitis B Surface Antibody (HBsAb or anti-HBs): The “surface antibody“ is formed in response to the hepatitis B virus. Your body can make this antibody if you have been vaccinated, or if you have recovered from a hepatitis B infection. If this test is positive, then your immune system has successfully developed a protective antibody against the hepatitis B virus. This will provide long-term protection against future hepatitis B infection. Someone who is surface antibody positive is not infected, and cannot pass the virus on to others. This is a Quantitative test required by many schools and medical programs ...

What is the difference between hepatitis B surface and hepatitis b antigen? Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection.

Clinical Education Center 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. Anti-HBs appears after convalescence from acute infection and lasts for many years.

Test Center 1 Hepatitis B core antibody (HBcAb) is an antibody to the hepatitis B core antigen that appears about 1 month after the start of an active HBV infection. 2  It can be found in people who had an infection in the past and in those with long-term (chronic) HBV.3  It usually is present for life. Blood banks test for this antibody when screening donated blood for hepatitis B. 2  Hepatitis B core antibody IgM (HBcAbIgM) is another antibody to the hepatitis B core antigen. 3  It indicates an HBV infection that has occurred within the last 6 months.

What Does a Reactive Result to a Hepatitis B Test Mean? In the hepatitis B surface antigen test, a reactive or positive result means that a person is currently infected with the hepatitis B virus, explains the Hepatitis B Foundation. Reactive results from the hepatitis B surface antibody test means that people are now immune to the virus because they have been infected in the past and their immune systems produced antibodies to fight the infection.

- Samples with weak but repeatedly positive reactivity (cutoff index greater than or equal to 1.0 but less than or equal to 20) will be resulted as GRAYZONE. If sufficient specimen is available, samples with GRAYZONE reactivity will be analyzed by the hepatitis B surface antigen neutralization test (a confirmatory test) by a reference laboratory. A negative surface neutralization reaction indicates that the patient does NOT have a positive surface antigen test.
