Hepatitis B Surface Antibody Blood Test (Labcorp)
The Hepatitis B Surface Antibody test is used to help determine if a person has immunity to Hep B. The surface ab test provides a quantitative numerical result for antibodies to Hepatitis B. In addition to the antibody measurement, test results include a reference range to help determine if you are immune or not.
Hepatitis B is a viral infection that affects the liver. Hep B is normally spread through bodily fluids including blood. Transmission of Hep B can occur through sexual contact. The virus can also be spread through other methods including contact with the blood or other fluids of a person with the virus, sharing needles during drug use, improperly sanitized tattoo or piercing equipment, and bites. It is possible for a pregnant woman to spread the infection to her infant during childbirth.
Most people in the United States are vaccinated against Hep B when they are infants or before entering school. How long a vaccination can provide immunity will vary from person to person. Some studies have shown that vaccines can provide protection for as much as 10-30 years or longer. However, some people may need a booster later in life to ensure continued protection. Measuring antibody levels can help determine if someone is still immune. People who have had Hepatitis B and recovered will also show protective antibodies. How long natural immunity to Hep B will last is undetermined.
The Hepatitis B Surface Antibody test is typically ordered by people who wish to know the status of their immunity for personal reasons or are required to present verification of their immune status. A record of immunity may be required for work, school, or travel. Request A Test also offers an Immunity Panel which combines titer testing for Hepatitis B, Varicella, and MMR.
A surface antibody blood test cannot show if someone has a current Hepatitis B infection. For that purpose, a Hep B Surface Antigen test is the most commonly ordered test.
The Hepatitis B Surface Antibody test typically sees results in 1 business day.
