What Is Hepatitis B Surface Antibody
When you are exposed to hepatitis B, your body mounts an immune reaction against it as an invader. This happens whether you are exposed due to blood or sexual contact or if you are vaccinated with the hepatitis B vaccine.
The hepatitis B virus has proteins on its surface that cause your immune system to produce antibodies. With the vaccine, the sample contains the protein only and not the virus itself.
The first response your body will make when exposed to hepatitis B is to manufacture hepatitis B IgM antibodies. These early antibodies are produced to fight against several parts of the virus including its core. These antibodies are seen in the initial response, but they eventually fade away.
Your immune system then begins to produce IgG antibodies. It continues to produce these antibodies for the rest of your life. In this way, your immune system is always ready to attack hepatitis B virus when it is exposed to it.

It means that the test result was positive for the antibody thatwas being tested.
If it is the Hepatitis B surface antibody then it means you havebeen exposed to either the infection of gotten the immunizations.
If it is other antibodies, such as the core or envelope, then itmeans you have been exposed to the infection at some point.
About 90% of adults who catch Hepatitis B get better on theirown so if you are antibody positive in order to know if you stillhave the infection you need to check a surface antigen or do a DNAtest.
How The Test Is Performed
Blood is most often drawn from a vein from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine . The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the provider gently inserts a needle into the vein. The blood collects into an airtight tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed. The puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
The blood sample is sent to a lab to be examined. Blood tests are used to check for antibodies to each of the hepatitis viruses.

What Does Reactive Result Mean In Hepatitis B
I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the
liver already present. I started on antiviral medications which
reduced the viral load initially. After a couple of years the virus
became resistant. I started on HEPATITIS B Herbal treatment from
ULTIMATE LIFE CLINIC in March, 2020. Their
treatment totally reversed the virus. I did another blood test after
the 6 months long treatment and tested negative to the virus. Amazing
treatment! This treatment is a breakthrough for all HBV carriers.
How To Get Tested
Hepatitis B testing is typically prescribed by a doctor and performed in a hospital, lab, or other medical setting. Taking a hepatitis B test requires a blood sample, which can be collected by a health care professional.
For laboratory-based testing, blood is drawn from a patientÃ¢s vein. After blood is collected, the sample is sent to a laboratory for 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 .

What Does A High Hepatitis B Surface Antibody Mean
Hepatitis B surface antigen : A protein on the surface of hepatitis B virus it can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious. The body normally produces antibodies to HBsAg as part of the normal immune response to infection.
What is hepatitis B Core Ab?
Hepatitis B core antibodies appear shortly after the onset of symptoms of hepatitis B infection and soon after the appearance of hepatitis B surface antigen . Initially, anti-HBc Ab consist almost entirely of the IgM class, followed by appearance of anti-HBc IgG , for which there is no commercial diagnostic assay.
What is a hepatitis B surface antigen?
Medical Definition of hepatitis B surface antigen. : an antigen that is usually a surface particle from the hepatitis B virus and that is found circulating in the blood serum especially of infected individuals abbreviation HBsAg. called also Australia antigen.
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 .

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.
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.

The Treatment Programs Role In The Screening Process
Medical staff members at substance abuse treatment programs might assume the primary role for screening individuals for and explaining the screening process and test results. Opioid treatment programs with medical staff members should screen for and C at intake and periodically as indicated. In programs without onsite medical staff, clients may be referred elsewhere for screening with minimal involvement of the substance abuse treatment program.
Regardless of the type of program, counselors should have a basic understanding of the importance of screening, the screening process, and the meaning of the results. Counselors can encourage clients referred for screening to follow through and complete the screening and evaluation process . Clients might feel anxious about being diagnosed with hepatitis, and they might delay or avoid getting screened.

Treatment Options For Hepatitis B
Acute hepatitis B usually doesnt require treatment. Most people will overcome an acute infection on their own. However, rest and hydration will help you recover.
Antiviral medications are used to treat chronic hepatitis B. These help you fight the virus. They may also reduce the risk of future liver complications.
You may need a liver transplant if hepatitis B has severely damaged your liver. A liver transplant means a surgeon will remove your liver and replace it with a donor liver. Most donor livers come from deceased donors.
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.
