What does positive anti-HBe mean?
Positive anti-HBe results usually indicate inactivity of the virus and low infectivity. Positive anti-HBe results in the presence of detectable HBV DNA in serum also indicate active viral replication in these patients.
Can HBeAg positive become negative?
Many people infected with hepatitis B at birth and who remain infected into their 40s, 50s or 60s, develop HBeAg-negative hepatitis B. Researchers believe that over time the virus mutates to evade the immune system.
What is HBsAg positive and HBeAg-negative?
If this HBsAg-positive, HBeAg-negative patient’s HBV DNA titer is currently ≥ 100,000 copies per mL in the presence of normal aminotransferases, the patient should undergo liver biopsy. If there is significant hepatic necroinflammatory disease and/or fibrosis found on biopsy, the patient will be eligible for treatment.
What does HBcAg positive mean?
HBcAg (core antigen) is a hepatitis B viral protein. It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
What does the E stand for in HBeAg?
An uninfected person vaccinated against hepatitis B will generate an immune response, or surface antibody (HBsAb, or anti-HBs) to the HBV vaccine. The hepatitis e antigen, or HBeAg, is a marker of an actively replicating HBV virus infection.
What is HBe in blood test?
The hepatitis e antigen, or HBeAg, is a marker of an actively replicating HBV virus infection. Those with a positive HBeAg have active replication in their liver cells, more of the virus circulating in their blood, and as a result, they are more infectious, with a higher likelihood of transmitting HBV to others.
What is the difference between HBsAg and HBcAg?
Presumably, this might not be associated with the stage of viral replication, although HBsAg is a major antigen for humoral immunity of hepatitis B, not that for cell-mediated immunity. It has been reported that HBcAg was stronger by 100 times than HBsAg in provoking the immune responses of B cell or T cell.
Why we do HBeAg test?
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.
What HBeAg reactive?
REACTIVE: A REACTIVE HBeAg indicates rapid viral replication usually associated with high HBV DNA levels. HBeAg-REACTIVE patients are considered highly infectious.
What is anti-HBe antibody test?
Anti-HBe are one of the antibodies produced by the body when it defends itself against hepatitis B. These antibodies are directed against the “soluble” or extractable part of the “core” antigen of the hepatitis B virus (HBV). An anti-HBe test that is reactive (positive) while HBeAg levels have dropped below the detection threshold indicates
What does positive anti-HBe antibody test results indicate?
Positive anti-HBe results in the presence of detectable HBV DNA in serum indicate active viral replication. See the following in Special Instructions: Absence of hepatitis B e antigen (HBeAg) with appearance of HBe antibody (anti-HBe) is consistent with inactivity of the virus and loss of hepatitis B virus (HBV) infectivity.
What is the difference between hepatitis B surface antigen and HBeAg?
While you are still infected with hepatitis B (you tested positive for the hepatitis B surface antigen – HBsAg), you do not test positive for the hepatitis B “e” antigen (HBeAg). Generally, when you are HBeAg-positive you have lots of virus in your blood and have a high viral load (HBV DNA).
What is the significance of the presence of anti-HBe?
The presence of anti-HBe serves to distinguish between these two phases. 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.
