Question 7 Is Hepatitis B Surface Antibody Antibody Always Acquired After A Completed Vaccination Protocol
No. After 3 intramuscular doses of vaccine, > 90% of healthy adults and > 95% of those < 19 years of age develop immunity .1 However, there is an age-specific decline in development of immunity. After age 40 years, about 90% of people become immune, but by age 60 years, only 75% of people become immune.1 Larger vaccine doses or an increased number of doses are required to induce immunity in many hemodialysis patients and in other immunocompromised people.1

Hepatitis B Surface Antibody
- Hepatitis B Surface Antibody
- Description
-
The Quantitative detection Hepatitis B virus Surface IgG antibody in human sera using the FDA approved Abbott ARCHITECT AUSAB-DIL test two-step chemiluminescent immunoassay.
In the first step, sample, assay diluent, and recombinant Hepatitis B surface Antigen coated paramagnetic microparticles are combined. Anti-HBs present in the sample binds to the rHBsAg coated microparticles. In the second step, rHBsAg acridinium-labeled conjugate is added, which binds to IgG anti-HBs. Then pre-trigger and trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units .
A direct relationship exists between the amount of anti-HBs in the sample and the RLUs. The concentration of anti-HBs in the sample is determined using an active ARCHITECT AUSAB calibration curve. Results are reported as mIU/mL.

Additional Specimen Collection Information
Collect blood in a lithium heparin, green-top, EDTA purple-topor red-top tube. PST and SST are acceptable. Serum orplasma should be separated from contact with the cells within 2hours of collection. Specimens not centrifuged within 4 hours ofcollection may be rejected. Refrigerate the specimen if unable toassay within 8 hours of collection. Samples with > 1+ lipemiamust be cleared prior to analysis.
Discussing Screening Results With Clients
The medical personnel who ordered or arranged the screening test, not counselors, usually explain the results. Hepatitis screening should be part of the intake physical examination in an opioid treatment program, and medical personnel may report the results. However, the client may want to discuss the results with the counselor or ask the counselor questions.
Anxiety might interfere with some clients ability to comprehend or retain information, which might need to be repeated.
Suggestions for conversations with clients when the test results are negative include the following:
- Explain results clearly and simply: So the HCV screening result was negative? This means that, as of 6 months ago, you did not have .
- Emphasize that a negative result to an HCV test does not indicate to and that the client should take precautions to avoid . If a relapse to drug use occurs, advise clients to avoid sharing any drug paraphernalia or equipment. Specify that this includes cookers, cotton, water, needles, syringes, pipes, and straws.
- Emphasize the importance of getting HAV and HBV vaccinations. Provide information about the availability of low- or no-cost vaccinations.
Clients whose screening test results are positive for will need additional tests and examinationsusually with doctors who specialize in diseases of the liver to get accurate diagnoses and to determine their health status and the extent of liver damage. These tests are described in .

Very satisified with my experience. Went to the website and choose my test, got the prescription thru email with in 30 minutes. Got blood draw the following morning at Lab Corp. Then got the result the following day thru secured emai link. Thats only 48 hrs from log in to result. Compared to my MD office which is 10 days to get the result and after multiple calls and only to find out that they performed a wrong lab test. Here you know what test they are performing since you are the one choosing.
What Is The Purpose Of A Hepatitis B Test
Hepatitis B test is performed to detect, classify, and treat hepatitis B virus infection.
Hepatitis B blood tests involve the measurement of several HBV-specific antigens and antibodies. In addition, HBV blood tests also include liver enzymes and liver function tests to assess and monitor the condition of the liver and provide appropriate treatment.
The HBV specific tests include the following:
- HBsAg: HBsAg is an antigen found on the surface of hepatitis B virus. HBsAg may be detected in the blood any time after 1 week post-exposure to HB virus, but usually appears after 4 weeks.
- Anti-HBs: Anti-HBs are antibodies produced by the bodys immune system to fight HBsAg. Anti-HBs from a prior infection or vaccination provides immunity against further infection.
- Hepatitis B core antigen : HBcAg is an antigen found in the core layer which covers the hepatitis B viral DNA.
- Hepatitis B core antibody : Anti-HBc is the antibody that fights HBcAg. Anti-HBc is the first detectable antibody after HBV infection. There are two kinds of Anti-HBc:
- Immunoglobulin M hepatitis B core antibody : IgM anti-HBc indicates acute or reactivated recent infection within the previous 6 months.
- Immunoglobulin G hepatitis B core antibody : IgG anti-HBc may indicate previous or chronic infection. Once present, IgG anti-HBc persists for a lifetime.

Laboratory Findings And Diagnostic Tests
Serum HBsAg and anti-HBs are the most useful screening tests for chronic HBV infection or immunity to HBV. HBsAg is present in most chronically infected persons. Lack of anti-HBs in an unvaccinated HBsAg-negative person indicates susceptibility to HBV infection.3
Screening for HBsAg is recommended at the first prenatal visit for all pregnant women.3,109 Women in labor without HBsAg test information should have HBsAg serology on arrival. In addition, pretested women who have a history of certain risk factors should be retested at the time of admission to the hospital for delivery.3,110

Negative But Other Hepatitis Tests Are Positive
Your HBsAb test may be negative even when other hepatitis B tests are positive, showing active or chronic infection. Further testing is necessary, especially for the hepatitis B surface antigen , which shows that the virus itself is circulating in your bloodstream and that you have an active or chronic infection.

Results And Next Steps
The results of a hepatitis B titer panel can help a doctor determine a persons hepatitis B status. The results can be confusing if a person has never been through this type of testing before, but the doctor can explain the findings.
The results for the titer come back as either negative or positive on each subtest of the panel. Positive means that the virus or antibodies showed up on the test, while negative means that they did not.
The following table outlines what positive and negative results mean on different parts of the test and the possible next steps.

Question 1 What Is The Clinical Indication For Hepatitis B Surface Antibody Quantitation
Hepatitis B surface antibody quantitation is used to determine hepatitis B immune status, ie, to determine if the patient has developed immunity against the hepatitis B virus. Such immunity may develop following exposure to the hepatitis B virus or its vaccine.
Patients at higher risk of exposure to the virus include:
- Infants born to infected mothers
- Sex partners of infected persons
- People with more than 1 sex partner in the last 6 months
- People with a history of sexually transmitted infection
- Men who have sex with men
- Injection drug users
- Household contacts of an infected person
- Healthcare and safety workers who have contact with blood and body fluids
- People who have lived or traveled in an area in which hepatitis B is common
- People who live or work in a prison
Testing is not recommended routinely following vaccination. It is advised only for people whose subsequent clinical management depends on knowledge of their immune status. These people include:
- Chronic hemodialysis patients
- Immunocompromised people, including those with HIV infection, hematopoietic stem-cell transplant recipients, and people receiving chemotherapy
- Infants born to women who test positive for the hepatitis B surface antigen
- Sex partners of people who test positive for the hepatitis B surface antigen
- Healthcare and public safety workers who have contact with blood or body fluids

How Much Does The Test Cost
The cost of hepatitis B testing depends on the tests that are performed, where the test is conducted, and a patients health insurance coverage. When testing is ordered by a doctor, patients with health insurance may find it helpful to discuss the cost of testing with their health insurance company as they may be responsible for testing costs as well as other out-of-pocket costs such as copays and deductibles.
For patients without health insurance or for whom insurance doesnt cover the cost of testing, it may be helpful to discuss the cost of hepatitis B testing with a doctor or hospital administrator.
The cost of at-home hepatitis B testing starts around $45. At-home test kits may also test for additional types of viral hepatitis in the same sample. The cost of test panels that look for more than one type of viral hepatitis start around $80.
