What is HBsAg II?
Immunoassay for the qualitative determination of hepatitis B surface antigen (HBsAg) Hepatitis B is a potentially life threatening liver infection caused by the hepatitis B virus (HBV). It is transmitted through contact with the blood or other body fluids of an infected person. 1.
What is the normal range of HBsAg?
For example, a hepatitis B surface antigen (HBsAg) level of less than 1 s/c is considered negative, while a level of more than 5 s/c is considered positive. Any value between 1 and 5 s/c is indeterminate and should be repeated.
What does hepatitis B surface AB HBsAb 2.0 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 if HBsAg test is positive?
If the “HBsAg” was positive, this means that you are either chronically infected with hepatitis B or were recently infected. If only the “anti-HBc” was positive, it is most likely that you either had a “false-positive” test or are immune to hepatitis B infection (had hepatitis B infec- tion sometime in the past).
What is the meaning of HBeAg?
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 HBsAg Quant?
The HBsAg quantitative assay records the amount of hepatitis B surface antigen in a patient’s blood. This, in combination with hepatitis B virus DNA (HBV DNA) testing, enables physicians to monitor and evaluate a patient’s response to peginterferon alfa-2a therapy, and to stop treatment after 24 weeks if indicated.
How long can you live if you have hepatitis B?
A “silent disease.” It can live in your body for 50+ years before you have symptoms. Responsible for 80 percent of all liver cancer in the world. Harder to fight off the younger you are; 90 percent of babies will go on to develop a chronic infection compared to 5 to 10 percent of adults.
How many types of HBsAg are there?
There are two types of hepatitis B infection: acute and chronic.
What is HBsAb negative?
Negative. If your HBsAb test is negative, it can mean many different thing. In general, it means that you are not immune to the virus. Even so, there are different ways to interpret the results based on their relationship to the other HBV tests.
What does low HBsAb mean?
* A low or negative result suggests primary vaccine failure in which case a repeat three-dose series should be given followed by HBsAb testing one to two months later. * except immunocompromised persons in which case protective titres should be considered valid for no more than one year.
Can HBsAg positive be cured?
There’s no cure for hepatitis B. The good news is it usually goes away by itself in 4 to 8 weeks. More than 9 out of 10 adults who get hepatitis B totally recover. However, about 1 in 20 people who get hepatitis B as adults become “carriers,” which means they have a chronic (long-lasting) hepatitis B infection.
Is hepatitis B very serious?
Chronic hepatitis B can develop into a serious disease resulting in long-term health problems, including liver damage, liver failure, liver cancer, and even death. There were 1,649 deaths related to hepatitis B virus reported to CDC in 2018, but this is an underestimate.
