What is it? ADVIA Centaur HBeAg Assay is a laboratory test used to detect human hepatitis Be antigen (HBeAg) in a person with a hepatitis B virus (HBV) infection. HBeAg is found in the blood only when the HBV virus is active. The presence of HBeAg in the blood often disappears after the HBV virus is cleared. Detection of HBeAg in the blood can determine if a person is chronically infected with HBV or if the infection is cleared. This test is designed for use on the ADVIA Centaur and ADVIA Centaur XP systems, which run the assay and analyze the results.

This test should not be used to:

  • Determine the final diagnosis of HBV infection or to determine the stage of infection.
  • Test cord blood specimens.
  • Screen blood plasma, tissue donors, immunocompromised or immunosuppressed persons, or test children under the age of 17.

How does it work? A sample of the patient’s blood is added to a small glass tube (cuvette) with the test chemicals. If there is HBeAg present in the blood, they attach to special anti-HBe antibodies to produce a light signal. The light signal is measured by the ADVIA Centaur and ADVIA Centaur XP systems. The ADVIA Centaur HBeAg Controls are used as a quality control to ensure that the test is working properly.

When is it used? The lab test result, as well as other clinical information and blood tests, is used in the diagnosis of chronic HBV or confirm recovery from HBV infection.

What will it accomplish? The lab test result will aid in the diagnosis of chronic HBV or confirm recovery from HBV infection.

When should it not be used? There are no known contraindications.
