HelpTest ID: HBBSN Hepatitis B Virus Surface Antibody Screen, Qualitative/Quantitative, Serum
Ordering Guidance
If patient is being monitored for hepatitis B immune globulin (HBIG) therapy after organ transplantation, order HBABT / Hepatitis B Virus Surface Antibody Monitor, Post-Transplant, Serum.
This test should not be used for prenatal screening of pregnant individuals with or without risk factors for hepatitis B virus (HBV) infection. For testing such, order HBABP / Hepatitis B Virus Surface Antibody Prenatal, Qualitative/Quantitative, Serum.
This test should not be used for diagnostic testing of symptomatic individuals to evaluate post-vaccination immunity status or post-acute infection status of HBV. For testing such patients, order HBAB / Hepatitis B Virus Surface Antibody, Qualitative/Quantitative, Serum.

Clinical Information
Hepatitis B virus (HBV) is a DNA virus that is endemic throughout the world. The infection is spread primarily through blood transfusion or percutaneous contact with infected blood products, such as sharing needles among injection drug users. The virus is found in virtually every type of human body fluid and has been known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions, but it is not commonly transmitted via the transplacental route.
The incubation period for HBV infection averages 60 to 90 days (range of 45-180 days). Common symptoms include malaise, fever, gastroenteritis, and jaundice (icterus). After acute infection, HBV infection becomes chronic in 30% to 90% of infected children younger than 5 years and in 5% to 10% of infected individuals 5 years or older. Some chronic carriers are asymptomatic, while others progress to chronic liver disease, including cirrhosis and hepatocellular carcinoma.
Hepatitis B surface antigen (HBsAg) is the first serologic marker, appearing in the serum 6 to 8 weeks following HBV infection. In acute cases, HBsAg usually disappears 1 to 2 months after the onset of symptoms with the appearance of hepatitis B surface antibody (anti-HBs). Anti-HBs also appears as the immune response following hepatitis B vaccination.

Interpretation
A positive result indicates recovery from acute or chronic hepatitis B virus (HBV) infection or acquired immunity from HBV vaccination. This assay does not differentiate between a vaccine-induced immune response and an immune response induced by HBV. A positive total hepatitis B core antibody result would indicate that the hepatitis B surface antibody (anti-HBs) response is due to past HBV infection.
Per assay manufacturer's instructions for use, positive results, defined as anti-HBs levels of 11.5 mIU/mL or greater, indicate adequate immunity to HBV from past hepatitis B or HBV vaccination. However, per current Centers for Disease Control and Prevention guidance,(1) individuals with anti-HBs levels greater than 10 mIU/mL after completing an HBV vaccination series are considered protected from hepatitis B infection.
Negative results, defined as anti-HBs levels of less than 8.5 mIU/mL, indicate a lack of recovery from acute or chronic hepatitis B or inadequate immune response to HBV vaccination. The US Advisory Committee on Immunization Practices does not recommend more than 2 HBV vaccine series in vaccine nonresponders.
Indeterminate results, defined as anti-HBs levels in the range from 8.5 to less than 11.5 mIU/mL, indicate inability to determine if anti-HBs is present at levels consistent with recovery or immunity. Repeat testing is recommended in 1 to 2 months to determine definitive anti-HBs status.
