What does hep B surface non reactive 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. In most cases this means that you will recover within 6 months.

What is the normal range for HBsAb?

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 does HBsAb positive mean?

■ Anti-HBs [sometimes written as HBsAb] (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.

What is HBsAb?

Antibody to hepatitis B surface antigen (HBsAb) is the antibody that best correlates with immunity to. hepatitis B virus (HBV).

What does high HBsAb mean?

When the HBsAb result is positive—meaning the surface antibodies are present—it usually means that you have recovered from a recent or prior hepatitis B infection and are immune to the virus. If both the HBsAb and HBcAb are positive, a person is said to be immune due to natural infection.

What does it mean when your Hep B is reactive?

A positive or “reactive” test indicates that a person may have been infected with the hepatitis B virus at some point in time. This test is often used by blood banks to screen blood donation, however, all three test results are needed to make a diagnosis.

How do you cure hepatitis B reactive?

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.

What does a positive Hep B surface AB mean?

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.

How are hepatitis B surface antibody anti-HBs results interpreted?

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.

What is Hep B surface AB?

Summary. The hepatitis B surface antibody (HBsAb) test detects and measures antibodies produced by the immune system in response to the hepatitis B virus. It is one of several tests used to diagnose hepatitis and is used specifically to determine your level of immunity to the virus.
