Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

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.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Hepatitis B Surface Antibody

Unvaccinated: Negative

Vaccinated: Positive

 

Hepatitis B Surface Antibody, Quantitative

Unvaccinated: <8.5 mIU/mL

Vaccinated: > or =11.5 mIU/mL

 

See Viral Hepatitis Serologic Profiles

Interpretation
Provides information to assist in interpretation of the test results

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.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

This assay has not been licensed by the US Food and Drug Administration for the screening of blood, plasma, and tissue donors.

 

For diagnostic purposes, the results should always be assessed in conjunction with the patient’s medical history, clinical examination, and other findings.

 

Assay performance characteristics have not been established for the use of the Elecsys Anti-HBs assay as an aid in determining susceptibility to hepatitis B virus infection prior to or following vaccination in infants, children, or adolescents.

 

A positive hepatitis B surface antibody (anti-HBs) result does not exclude infection by another hepatitis virus.

 

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 anti-HBs results due to passive transfer of anti-HBs present in these products. In rare cases, interference due to high titers of antibodies to immunological components, streptavidin or ruthenium can occur, causing false-positive anti-HBs results.

 

Serum specimens from individuals taking biotin supplements of 20 mg or more per day may have negative anti-HBs test results due to interference of biotin with the assay. Such individuals should stop taking these biotin-containing dietary supplements for a minimum of 12 hours before blood collection for this test.

 

Anti-HBs levels from past hepatitis B or hepatitis B virus vaccination may fall below detectable levels over time. Negative anti-HBs test results from immunosuppressed individuals should be interpreted with caution.

 

Results obtained with the Elecsys Anti-HBs immunoassay may not be used interchangeably with values obtained with different manufacturers’ assay methods.

 

Assay performance characteristics have not been established for the following specimen characteristics or specimen types:

-Grossly icteric (total bilirubin level of >30 mg/dL)

-Grossly lipemic (intralipid level of >1500 mg/dL)

-Grossly hemolyzed (hemoglobin level of >1600 mg/dL)

-Containing particulate matter

-Heat-inactivated specimens

-Cadaveric specimens

-Specimen types other than serum

Method Description
Describes how the test is performed and provides a method-specific reference

The Elecsys Anti-HBs (hepatitis B surface antibody) assay is based on the sandwich immunoassay principle and performed using an electrochemiluminescent immunoassay on the automated cobas e 801 immunochemistry analyzer. Anti-HBs present in patient's sample reacts with the biotinylated HBs antigen (ad and ay subtypes) and HBs antigen (ad/ay) labeled with a ruthenium complex to form a sandwich complex. After the addition of streptavidin-coated microparticles (solid phase), the complexes bind to the solid phase via interaction of biotin and streptavidin. The reaction mixture is aspirated into the measuring cell where microparticles are magnetically captured onto the surface of the electrode. Unbound substances are then washed away, and voltage is applied to the electrode, which induces chemiluminescent emissions that are measured by a photomultiplier. The emission signal generated is directly proportional to the concentration of anti-HBs present in the patient's sample.(Package insert: Elecsys Anti-HBs. Roche Diagnostics; v3.0, 03/2024)
