What is it? The Elecsys HBeAg Immunoassay is a laboratory test used to detect human hepatitis B e antigen associated with the hepatitis B virus (HBV) infection. Hepatitis B e antigen is a protein of the hepatitis B virus which is sometimes present in the blood during an acute infection, usually disappearing afterward but sometimes persists in chronic disease.

The presence of the hepatitis B e antigen can help determine if a person is acutely infected or chronically infected with HBV, or is recovered from HBV infection. This test is designed for use on the MODULAR ANALYTICS E170 immunoassay analyzer which runs the assay and analyzes the results.

The Elecsys PreciControl HBeAg is used as a quality control to ensure that the test is working properly.

How does it work? A person’s blood sample is mixed with the test chemicals in a tube. If there is hepatitis B e antigen in the blood, it attaches to special anti-HBe antibodies to generate a light signal. The light signal is measured by the MODULAR ANALYTICS E170 analyzer.

When is it used? The test result is used in combination with other clinical information and blood tests to aid in the laboratory diagnosis of adult patients with acute or chronic hepatitis B, or recovering from hepatitis B infection.

What will it accomplish? Results of this test, in combination with other clinical information and laboratory blood tests, may be used by the clinician to aid in the laboratory diagnosis of individuals with acute or chronic hepatitis B, or recovering from hepatitis B infection.

When should it not be used? This test has not been FDA licensed for screening blood, plasma, tissue donors or for testing immunocompromised or immunosuppressed persons.
