What HBeAg Test Results Mean. A positive test for the hepatitis B e-antigen means that there is an active infection with the hepatitis B virus and the virus is actively multiplying. Anyone who is in contact with your blood without protection may be at risk of contracting hepatitis B from you.
Is HBeAg negative good or bad?
HBeAg‐negative CHB is a potentially severe disease that rapidly progress to cirrhosis and related complications. Although treatment is available, sustained virological and biochemical response is poor after the recommended duration of treatment.
What is the normal result of anti-HBs?
For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
What is HBsAg test negative mean?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
Is HBeAg negative infectious?
A negative HBeAg result indicates very minimal or no HBV replication. 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.
What is e antigen negative chronic hepatitis B?
Hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) occurs at the late phase in hepatitis B virus (HBV) infection’s natural history. The disease is characterized by progressive liver damage due to variants with mutations in the precore/core promoter region that reduce or abolish HBeAg expression.
How do I know if I had hepatitis B vaccine?
To be certain that you are protected against hepatitis B, ask for a simple blood test to check your “antibody titers” that will confirm whether the vaccination was successful.
What does high anti-HBs mean?
anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection.
Can I donate blood if I have hepatitis B antibodies?
People infected with hepatitis B may carry the virus without even knowing it. They can pass it to others through blood or sexual contact. Because of this, anyone who has ever tested positive for hepatitis B cannot donate blood.
