What does it mean if 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 is the difference between Hep B antigen and antibody?
HBsAg: Hepatitis B surface antigen is a marker of current infection. Its presence indicates either acute or chronic HBV infection. Anti-HBs: Antibody to hepatitis B surface antigen is a marker of immunity.
What does a non-reactive titer mean?
If you have been tested for HIV infection, you may be told that the result is ‘non-reactive’. This means that the test did not find any evidence of HIV infection.
What does hepatitis B non immune mean?
NOT IMMUNE– has not been infected. but is still at risk for possible future. infection – needs vaccine. Get the vaccine.
What is borderline Hep B surface antibody?
Borderline results may indicate a low level of antibody that has clinical significance. Patient’s immune status should be further assessed by considering other clinical information or retesting another specimen drawn at a later time.
What is hep be antigen?
HBeAg stands for hepatitis B e-antigen. This antigen is a protein from the hepatitis B virus that circulates in infected blood when the virus is actively replicating. The presence of HBeAg suggests that the person is infectious and is able to spread the virus to other people.
Does non reactive mean positive?
If you did not test positive for coronavirus already, another test may be needed to see if you are currently infected. Nonreactive: A nonreactive result means that IgG antibodies to the virus were not present in the blood. However, you may still be infected which can be detected by the molecular test.
Is non reactive the same as negative?
Nonreactive vs. A nonreactive result means that the fluid sample did not contain HIV antigens or antibodies that the test aims to react to at the time of testing. It can mean a person has tested negative for HIV. However, if an individual has a nonreactive result, it does not necessarily mean they do not have HIV.
What does non-reactive mean on hepatitis test?
What does a non-reactive HCV antibody test result mean? ► A non-reactive or negative antibody test means that you are not currently infected with the hepatitis C virus. ► However, if you think you might have been exposed to hepatitis C in the last 6 months, you will need to be tested again.
Is non-reactive the same as negative?
What does it mean if Hep B surface antibody is non reactive?
Hep B antigen “non-reactive”. My understanding is that surface antigen positive means you are infected regardless of any antibody status. If you clear the antigen and develop antibodies, then you are immune. So, get a hard copy of your lab results and then post them here. As a carrier you are “contagious” but…
How to test for Hep B virus?
Hepatitis B blood tests detect viral proteins ( antigens ), the antibodies that are produced in response to an infection, or detect or evaluate the genetic material ( DNA) of the virus. The pattern of test results can identify a person who has a current active infection, was exposed to HBV in the past, or has immunity as a result of vaccination.
What is the normal range for hepatitis B surface antibody?
Reference Range. 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, 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 hepatitis B virus surface AB?
Hepatitis B virus (HBV) is a DNA virus in the Hepadnaviridae family. It has a lipoprotein-coated surface, which is called the surface antigen (HBsAg, previously called Australia antigen).
