HelpTest ID HBBSN Hepatitis B 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 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 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 Surface Antibody, Qualitative/Quantitative, Serum.

Clinical Information
Hepatitis B virus (HBV) infection, also known as serum hepatitis, 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 of age and in 5% to 10% of infected individuals 5 years of age 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 16 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.

Reference Values
HEPATITIS B SURFACE ANTIBODY
Unvaccinated: Negative
Vaccinated: Positive
HEPATITIS B SURFACE ANTIBODY, QUANTITATIVE
Unvaccinated: <5.0 mIU/mL
Vaccinated: ≥12.0 mIU/mL
Cautions
Individuals who have received blood component therapies (eg, whole blood, plasma, or intravenous immunoglobulin infusion) in the previous 3 to 6 months may have false-positive hepatitis B surface antibody (anti-HBs) results due to passive transfer of anti-HBs present in these products.
Individuals possessing IgM anti-rubella virus may have falsely high results with the VITROS Anti-HBs quantitative test.
Anti-HBs levels from past hepatitis B or hepatitis B virus vaccination may fall below detectable levels over time.
A positive anti-HBs result does not exclude infection by another hepatitis virus.
Performance characteristics have not been established for the following specimen characteristics:
-Grossly icteric (total bilirubin level of >20 mg/dL)
-Grossly lipemic (triglyceride level of >3000 mg/dL)
-Grossly hemolyzed (hemoglobin level of >500 mg/dL)
-Containing particulate matter
-Cadaveric specimens
-Body fluids other than serum (eg, saliva, urine, spinal fluid, amniotic, peritoneal, or pleural fluids)

Method Description
The VITROS hepatitis B surface antibody (anti-HBs) quantitative assay is performed using an immunometric technique in which the anti-HBs present in the clinical serum sample reacts with hepatitis B surface antigen (HBsAg) (ad and ay subtypes) coated onto the assay reaction wells. A horseradish peroxidase (HRP)-labeled HBsAg conjugate (ad and ay subtypes) then complexes with the bound anti-HBs forming an "antigen sandwich." Unbound materials are removed by washing.
A reagent containing luminogenic substrates (a luminol derivative and a peracid salt) and an electron transfer agent are added to the wells. HRP in the bound conjugate catalyzes the oxidation of the luminol derivative to produce light. The electron transfer agent increases the level and duration of the light produced. The light signals are detected by the system. The amount of HRP conjugate bound is directly proportional to the concentration of anti-HBs antibody present.(Package insert: VITROS Anti-HBs Quantitative Assay, no. GEM1208_US_EN.
