This test is used to determine the status of a person’s immunity to the Hepatitis B virus (Heb B). Immunity is determined by screening for antibodies which provide protection against infection. The results for this test are quantitative.
Hepatitis B is a viral infection of the liver spread through contact with contaminated bodily fluids including blood. Transmission can occur through various types of exposure including sexual contact. It is possible for a pregnant woman to spread the infection to her infant during childbirth. More than half of Hep B infections display no symptoms. When symptoms do occur, the most common are loss of appetite, fatigue, nausea, abdominal pain, jaundice, and dark colored urine. Chronic Hepatitis B infections may lead to the development of Cirrhosis or Liver Cancer.
A person can have immunity to Hepatitis B for several reasons.
1.) They have been vaccinated for Hep B. Vaccinations do not always provide permanent immunity. It is possible for a person to have been vaccinated and lose their immunity over time.
2.) They have been infected with Hep B, recovered, and now have a natural immunity. Because Hepatitis B does not always display symptoms, it is possible for a person to have been exposed and not be aware of it.
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.
A person who wished to screen for a current Hepatitis B infection, may wish to order the Hep B Surface Antigen test.
The Hepatitis B Surface Antibody test typically sees results in 1 business day.
The incubation period varies but ranges between 3-12 weeks.
