What Are My Next Steps Once I Get My Results
It can be difficult to understand what the results of your test mean. A healthcare provider can help you interpret your results and decide whether you need to take further action:
- If your results suggest that youre already immune to hepatitis B and arent contagious, you likely wont need to do anything.
- If your results suggest that youre not immune, a doctor may recommend vaccination, especially if youre somebody whos at a high risk of infection.
You may also need additional testing if more information is needed to interpret your results.

Question 5 What Is The Natural History Of Hepatitis B Surface Antibody During Acute Hepatitis B Infection And Convalescence
HBsAg can be detected in the blood 4 to 10 weeks after exposure. This corresponds to onset of symptoms and viremia detectable by nucleic acid amplification methods. Most hepatitis B infections are self-limited and are associated with disappearance of HBsAg within 4 weeks of onset of symptoms. The anti-HBs then appears and increases to a plateau level that persists indefinitely.2

What Does Hepatitis B Surface Antibody Ql Reactive Mean
If this test is positive or reactive, then your immune system has successfully developed a protective antibody against the hepatitis B virus. This will provide long-term protection against future hepatitis B infection. Someone who is HBsAb+ is not infected and cannot pass the virus to others.
Can reactive hepatitis B be cured?
Most adults with hepatitis B recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic hepatitis B infection. A vaccine can prevent hepatitis B, but theres no cure if you have the condition.
What is the normal level for Hep B surface AB?
For hepatitis B surface antibody , a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.

Question 7 Is Hepatitis B Surface Antibody Antibody Always Acquired After A Completed Vaccination Protocol
No. After three 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

Why Do I Need This Test
You may need this test if your healthcare provider suspects you have a liver infection caused by HBV. You may also need this test if you have symptoms of hepatitis B. Symptoms usually start slowly. Many people have no symptoms or only feel like they have a mild case of the flu. You may not have symptoms until the infection is chronic or severe.
The most common symptom is extreme tiredness. Other symptoms may include:
-
Swelling and confusion. This is in extreme cases.
You may also have this test if you have a history that puts you at risk for being in contact with the virus. Risk factors for hepatitis B infection include:
-
Having sex with someone infected with the virus
-
Living in close contact with someone who has the virus
-
Being a man who has sex with men
-
Being a child born to a mother who has the virus
-
Sharing needles for intravenous, or IV, drug use
-
Working in a healthcare center where you are exposed to blood
-
Getting a blood transfusion or organ transplant. This is less common with active screening.

Question 3 How Is The Quantitative Hepatitis B Surface Antibody Test Performed
An immunometric technique is used. The anti-HBs binds to HBsAg ad and ay subtypes, which are coated on the test wells. Binding of a horseradish peroxidase-labeled HBsAg conjugate to the anti-HBs completes the sandwich formation. Unbound materials are then washed away. In the next step, the horseradish peroxidase catalyzes oxidation of a luminogenic substrate, producing light. Light signals are detected and quantified. Intensity of the light is proportional to the amount of anti-HBs present in the patient sample. The result is standardized to an international unit system and reported as milliinternational units per milliliter .

Can Hepatitis B Be Prevented
The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.
The disease has also been more widely prevented thanks to:
- Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
- Safer blood injection practices, using clean needles.
- Safe-sex practices.
You can help prevent hepatitis B infections by:
- Practicing safe sex .
- Never sharing personal care items like toothbrushes or razors.
- Getting tattoos or piercings only at shops that employ safe hygiene practices.
- Not sharing needles to use drugs.
- Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

When Should You Have The Test
Anyone who has symptoms of hepatitis B may benefit from having the test. Other people who may consider undergoing the hepatitis B panel test are those with known risk factors. These people include individuals born in places with a high incidence of HBV infection and those who use needles to inject drugs.
Educating Clients About Viral Hepatitis
Clients may believe they know about viral , but their understanding of the disease may not be accurate. It is easy to confuse the three main types of viral , B, and C. Clients may have formed impressions based on limited or incorrect information. Counselors should briefly describe hepatitis A, B, and C, including their prevalence, , and relationship to drug use, as well as to other infections, such as HIV and sexually transmitted diseases. Specific strategies for speaking with clients include:
- Speak clearly and keep the message simple, focused, and brief.
- Use language, examples, and concepts that the client understands.
- Use appropriate visual aids.
- Frame numerical statements in terms that are easy to visualize. Say 5 out of 100 people rather than 5 percent of the population say more than half instead of the majority.
- Repeat the information at different times in different ways. The average client retains only approximately one-third of what he or she is told. Summarize essential points.
- Pay attention to a clients response to the information. For example, if a client stiffens his or her posture, consider saying, I notice that this topic seems to make you uncomfortable. It does for a lot of people. Please tell me what youre feeling right now. Id really like to help you with this.
- Use the opportunity to describe the potential detrimental effects of alcohol and other substance use on the liver of a person who is infected with HCV.

What Foods Should I Avoid
Everyone should avoid eating a lot of fat, cholesterol, salt and processed sugar, even if their liver is healthy. In addition, those with HCV should limit or avoid alcohol. Drinking alcohol will speed up liver damage.
Eating properly can help decrease some of the symptoms of Hepatitis C, like feeling tired and sick. Drink lots of water for general health benefits. HCV is not a digestive disease diet will not affect the disease. Your provider may put you on a special diet if you have advanced liver disease.

What Is Hepatitis C
Hepatitis C is a virus that causes inflammation of the liver. It is a member of the family of viruses that includes hepatitis A and hepatitis B. These viruses behave differently and have different modes of transmission. Hepatitis C can cause serious liver damage, liver failure, liver cancer, and even death.

Question 2 What Is The Hepatitis B Surface Antibody
The hepatitis B surface antibody is the antibody that is produced in response to hepatitis B surface antigen , a protein present on the surface of the hepatitis B virus. Anti-HBs appears after convalescence from acute infection and lasts for many years. It can also be produced in response to hepatitis B vaccination.
Other hepatitis B antibodies are not produced in response to vaccination. This is because these antigens are not in the vaccine.

What Does It Mean When Hepatitis Is Reactive
A reactive or positive antibody test means you have been infected with the hepatitis C virus at some point in time. Once people have been infected, they will always have antibodies in their blood. This is true if they have cleared the virus, have been cured, or still have the virus in their blood.
What does it mean if hepatitis B surface antibody is non reactive?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months.
What is the difference between Hep B surface antigen and antibody?
The basic blood test for hepatitis B consists of three screening tests: a hepatitis B surface antigen test, which determines whether a person currently has the infection a hepatitis B core antibody test, which determines whether a person has ever been infected and a hepatitis B surface antibody test, which determines

What Are Normal Titer Levels
The normal values of an antibody titer depend on the type of antibody. If the testing is done to detect autoantibodies, the normal value should essentially be zero or negative. In the case of testing the efficacy of a vaccine, the normal test result depends on the definite value that is specific for that immunization.
What does it mean if your anti HBs test is negative?
However, the fact that the negative Anti-HBS result does not mean that the person is not suffering from hepatitis B and is not affected by infection. In order to understand this condition, the level of HBsAg known as Hepatitis B surface antigen test should be checked.
What doeshbsag non-reactivemean for hepatitis B?
A non-reactive result for hepatitis B surface antigens means that you dont have an infection. So, its negative. If it were positive or reactive, it would mean that you had an ongoing acute or chronic hepatitis B infection.
Why It Is Done
You may need testing if:
- You have symptoms of hepatitis.
- You may have been exposed to the hepatitis B virus. You are more likely to have been exposed to the virus if you inject drugs, have many sex partners, or are likely to be exposed to body fluids .
- You’ve had other tests that show you have liver problems.
- You are pregnant.
- You or your doctor wants to know if you are protected from getting the disease.
The tests also are done to help your doctor decide about your treatment and see how well it’s working.

Persons With Inadequate Immunization Records
Evidence of long term protection against HB has only been demonstrated in individuals who have been vaccinated according to a recommended immunization schedule. Independent of their anti-HBs titres, children and adults lacking adequate documentation of immunization should be considered susceptible and started on an immunization schedule appropriate for their age and risk factors. Refer to Immunization of Persons with Inadequate Immunization Records in Part 3 for additional information.
Guidance On Reporting Adverse Events Following Immunization
Vaccine providers are asked to report, through local public health officials, any serious or unexpected adverse event temporally related to vaccination. An unexpected AEFI is an event that is not listed in available product information but may be due to the immunization, or a change in the frequency of a known AEFI.
Refer to Reporting Adverse Events Following Immunization in Canada and Adverse events following immunization in Part 2 for additional information about AEFI reporting.

Concurrent Administration Of Vaccines
HB-containing vaccines may be administered concomitantly with other vaccines or with HBIg. Different injection sites and separate needles and syringes must be used for concurrent parenteral injections.
Refer to Timing of Vaccine Administration in Part 1 for additional information about concurrent administration of vaccines.
What Is Hepatitis B
Hepatitis B is a serious liver infection caused by the hepatitis B virus . For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosisa condition that causes permanent scarring of the liver.
Most people infected with hepatitis B as adults recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic hepatitis B infection.

Recommended Laboratory Evaluation Prior To Referral
All persons referred for further evaluation and management of HCV infection should have a confirmed positive HCV RNA level, preferably a quantitative HCV RNA level and not a qualitative HCV RNA level. It is ideal, but not imperative, that the clinician who makes the diagnosis of HCV infection can perform some preliminary tests to provide advanced information in anticipation of the initial referral visit. These initial preliminary tests include an HCV genotype, tests of synthetic liver function , hepatic inflammation , and assays to detect relevant coinfection . For primary care providers taking on a more comprehensive role for the initial evaluation and management, see Module 2, Lesson 1 for a detailed discussion in the Core Concept Initial Evaluation of Persons with Chronic Hepatitis C.
