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.
Taking A Hepatitis B Test
Testing for hepatitis B is performed on a sample of blood. A doctor, nurse, or other health care provider can obtain a blood sample using a small needle to draw blood from a vein.
At-home hepatitis B testing requires that users carefully follow instructions provided in the test kit to collect a small sample of blood, package the sample, and mail it to a lab for testing.

What Is Hepatitis B Surface Antibody
When you are exposed to HBV, your body mounts an immune defense to specifically target and neutralize the invader. Unlike innate immunity which mounts a generalized defense against all invaders, this type of immunity is disease-specific.
This immune response occurs whether you are exposed to HBV through blood or sexual contact, or if you are vaccinated with the hepatitis B vaccine.
The virus has proteins on its surface, called antigens, that serve as unique identification tags. When HBV enters the body, the immune system “encodes” antibodies specific to these antigens so that it can recognize and attack the virus should it appear again.
There are two types of antibodies produced in response to the virus:
- Immunoglobulin M is the antibody that mounts the initial attack but eventually fades away.
- Immunoglobulin G is the antibody that provides long-lasting immune protection against HBV. The immunity can last for many years, but it gradually wanes over time.

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 patientâs vein. After blood is collected, the sample is sent to a laboratory for analysis.
Hepatitis B Surface Antigen Test
A hepatitis B surface antigen test shows if youre contagious. A positive result means you have hepatitis B and can spread the virus. A negative result means you dont currently have hepatitis B. This test doesnt distinguish between chronic and acute infection. This test is used together with other hepatitis B tests to determine the .

How Do You Get Hepatitis C
Hepatitis C is a blood-borne illness, meaning it is transmitted via contact with infected blood. Usually the virus enters the body through a puncture wound on the skin. The most common way hepatitis C is transmitted is via injection drug use. Sharing dirty needles with someone who is infected can transmit hepatitis C. Health care professionals may contract the virus via needlestick injury. Prior to 1992, the U.S. blood supply was not screened the way it is today, so some people contracted hepatitis C from infected blood transfusions. Rarely, babies born to hepatitis C-infected mothers acquire the virus. Hepatitis C can also be spread by having sex with an infected person or sharing personal items with someone who has the virus, but these cases are rare.
Results Of The Hbcab Test
There are two variations of antibodies. The IgM antibody is the largest antibody and the first produced in an infection. It shows that you may have a current, active infection. Sometimes it persists for years, but it usually drops to undetectable levels.
The HBcAb IgG variant is produced later in the course of the infection, and its likely that you will have a positive HBcAb IgG test the rest of your life.
The screening panel usually has a test that is for total HBcAb, which includes both IgM and IgG. The IgM test may be ordered to help determine if you have an acute infection.
A positive HBcAb test must be interpreted along with the results of the other tests. You may have an active or chronic infection, or you may be immune to hepatitis B due to past infection. Discuss the results with your healthcare provider. In any case, a positive HBcAb test means your blood or organs cannot be donated to a recipient.

How Is The Hbcab Test Done
This is a blood test. A clinician will fill a tube with blood taken from a vein in your arm through which a needle is inserted. If you are giving blood, a sample will be taken from the blood youre donating. The blood is sent to a lab, where it is tested. Sometimes HBcAb will be added on to lab orders when results from other tests indicate there may be a hepatitis B infection.
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.

Preparing Clients For Screening
Once clients are comfortable talking about viral , they might be more willing to undergo screening. However, clients might be anxious about the test itself a reassurance that testing is a simple procedure can help allay these concerns. Many substance use treatment facilities do not offer screening, and clients might need to be referred elsewhere.

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.

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.
What Do Hepatitis B Test Results Mean
Hepatitis B test results help determine if HBV infection is negative or positive, and if positive, whether the infection is acute or chronic, or if recovery is complete. A combination of results are considered to identify and classify HBV infection status.
The following are some interpretations of hepatitis B test results:

What Do My Test Results Mean
Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you.
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. If you recover, you will have immunity from the virus and will not be able to pass the virus to others. A positive test may also mean you have chronic hepatitis B infection. If you dont recover in 6 months, the virus may stay in your blood and cause liver problems. You can also infect others. Your healthcare provider may give you medicines if you dont recover after 6 months.

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.

Hepatitis refers to liver inflammation caused by a viral infection. This is one of the most widespread and contagious diseases in the world with more than 400 million people being a carrier of the hepatitis B virus. When the hepatitis B virus is actively circulating and replicating in the blood, it produces the hepatitis B antigen protein. The presence of this antigen protein means that the person is infected with the virus and can spread the infection to other people.

Screening Tests For Hepatitis B
Your blood may be screened for HBV for many different reasons. There are several types of test, but the three generally included are the HBsAg, the antibody to HBsAg , and the antibody to hepatitis B core antigen .
These tests allow the healthcare provider to know whether you could benefit from vaccination, or if you have active or chronic hepatitis B and need counseling, care, or treatment.
You may be routinely screened if you are pregnant, are donating blood or tissue, need immunosuppressive therapy, or have end-stage renal disease. You will also be screened if you are in groups that are at higher risk for HBV.
Counseling Practices That Educate Support And Motivate Clients Undergoing Screening
Clients might need help deciding whether to get screened, understanding the test results, and determining their next steps. Even when services offered through the substance abuse treatment program are limited, discussing testing with clients presents an opportunity for counselors to motivate clients for change by confronting substance use and by making choices that improve their overall health. However, this may also be true when services are offered on-site through substance abuse treatment programs. A study at one methadone clinic that offered hepatitis screening and vaccination revealed that although the majority of clients completed screening , only 54.7 percent of clients who lacked for hepatitis A received vaccinations and only 2.9 percent of clients who lacked immunity for received vaccinations .
The Consensus Panel makes the following general recommendations while recognizing that, in some programs, the counselors role may be limited:

Does Hepatitis B Show Up In Routine Blood Tests
Routine blood tests do not detect hepatitis B virus infection. Hepatitis B tests are specifically done if blood tests show abnormal liver function results, or if a person experiences symptoms or falls into the high-risk category for HBV infection.
A panel of HBV-specific blood tests are required to detect HBV infection.
