What does hepatitis B antibody non reactive mean?

What does hepatitis B antibody non reactive mean?

Normal results are negative or nonreactive, meaning that no hepatitis B core IgM antibodies were found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases, this means that you will recover within 6 months.

What blood test shows immunity to hepatitis B?

Hepatitis B surface antibody (anti-HBs): The presence of anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.

Is it normal to have hep B antibodies?

The presence of anti-HBs following a new acute infection generally indicates recovery and a person is then protected (or “immune”) from re-infection with hepatitis B. Anti-HBc or HBcAb (hepatitis B core antibody) – this blood test remains positive indefinitely as a marker of past HBV infection.

What does positive Hep B antibody 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.

What does it mean when hepatitis B surface antibody is reactive?

(antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection. (This test is not done routinely by most blood banks on donated blood.)

What does it mean when your hepatitis B core antibody is reactive?

A fourth blood test that is sometimes done is IgM anti-HBc (IgM class antibody to hep- atitis B core antigen). When this is positive or “reactive,” it means that the person has had hepatitis B infection in the past six months, indicating acute (recently acquired) hepatitis B infection.

What is the normal range for Hep B antibody?

Reference Range. For example, a hepatitis B surface antigen (HBsAg) level of less than 1 s/c is considered negative, while a level more than 5 s/c is considered positive. Any value between 1 and 5 s/c is indeterminate and should be repeated. For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative,…

What does hepatitis B core antibody being positive mean?

A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood. 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.

Are there blood tests for hepatitis B?

What does a non reactive Hep B surface antibody mean?

HbsAb means “hepatitis B surface antibody”. Non-reactive means no antibody. This result means you have never been exposed to hepatitis B so are not infected with the disease. However it also means you have no immunity to it and are at risk of getting it in the future,…
