What is it?
The Elecsys Anti-HBe is a laboratory test used to detect human antibodies against the hepatitis B virus e antigen (Anti-HBe) in a patient’s blood. Anti-HBe may be detectable in patients with a recent (acute) hepatitis B virus (HBV) infection and in some patients with long-term (chronic) HBV infection.
This test is used with the cobas e 602 immunoassay analyzer, which runs the assay and analyzes the results.
The PreciControl Anti-HBe is used as a quality control to ensure that the test is working properly.
How does it work?
A sample of a patient’s blood is obtained and sent to a clinical laboratory. The serum or plasma containing the antibody is separated from the other parts of the blood and then mixed with the test chemicals. If there is Anti-HBe in the sample, a light signal is produced and measured by the cobas e 602 analyzer.
When is it used?
The Elecsys Anti-HBe is intended to be used to aid doctors in the diagnosis of HBV infection in adult patients previously shown to have hepatitis B virus e (HBeAg).
What will it accomplish?
Doctors use the test results together with a patient’s medical history and other blood tests to help diagnose HBV infection in patients with signs and symptoms of hepatitis or in patients at risk for hepatitis B infection. In patients with chronic HBV infection, a change from having HBeAg detected in their blood to having anti-HBe antibody may mean improvement in health, reduced chance of infection, and better outcomes.
When should it not be used?
The Elecsys Anti-HBe should not be used for screening blood, plasma or tissue donors.
