What is the Hepatitis B Antibody test?

The Hepatitis B Antibody test helps to determine the amount of hepatitis B antibodies in your blood. When you experience hepatitis B, antibodies develop in your blood. Antibodies are proteins that are produced by the immune system. They help to fight and protect your body against bacteria, infection, and other diseases. The availability of antibodies in your blood indicates that you fully recover and get immunity from the hepatitis B virus. Anti-HBs may also develop in a person who takes a vaccine for hepatitis B.

The Hepatitis B virus (HBV) is an antigen that lowers the strength of your immune system. The immune system consists of organs, proteins, cells, and tissues. These cells of the immune system prevent your body from germs, bacteria, viral infections, and specific diseases. HBV infection spreads during the blood transfusion or whenever a person comes in contact with infected blood components, like taking drug injections with the same needles. HBV is present all over the world in people, specifically can transmit to others through oral and genital contact. On average, HBV lasts about 60 to 90 days in a person’s body.

The positive test results for anti-HBs indicate that you have antibodies in your blood. The results show the recovery from acute or chronic hepatitis B virus. The recommended levels of anti-HBVs in your blood should lie equal to or greater than 12 mlU/mL (milli-international units per milliliter). It means that you are immune to the HBV virus or HBV vaccination. According to CDC (Centers for Disease Control and Prevention), a person should be considered safe from hepatitis B if the values for anti-HBs are higher than ten mlU/mL after the completion of an HBV vaccination.

The value for the hepatitis B antibody test below five mIU/mL shows negative results. It means that you have no antibodies in your blood. The test results indicate that you have acute or chronic hepatitis B or an insignificant immune response to HBV vaccination. In general, the virus recovers automatically within six months. If the virus does not disappear, it can cause liver problems. You can transfer the virus to others.

The anti-HBs levels between 5 to 11.9 mIU/mL indicate indeterminate results. The test results do not determine the consistency levels for anti-HBs in your blood. Your provider will ask to repeat the test within 1 to 3 months.
